With the communication industry consistently growing, it is best to be prepared for any environmental factors. From direct sunlight factors to wet locations, a reliable connection cannot afford to be overlooked.
For those locations; the industry’s original water resistant, water blocking low-voltage cable- Aquaseal cable, has become the recognized name for indoor/outdoor applications.
What is considered a Wet Location?
Wet locations occur in areas where direct burial in the ground, in conduit that is located below grade or any time the cable is passing through the concrete slab. These are areas where water, humidity or liquid saturation is possible- regions that are regularly exposed to the elements.
So how does it work?
Aquaseal low-voltage cable consists of a 2-ply tape on the inner shielded pairs which is virtually impenetrable. As well as a .025 inch sunlight resistant and moisture resistant jacket. Aquaseal contains this material, so when the water penetrates the cable, the 2-ply tape expands to protect the cables and connections.
Advantage of West Penn Wire’s Aquaseal cable versus the competitor:
2-ply tape material immediately expands to absorb any type of moisture to 10 mm within the first minute
Expands to 12 mm after ten minutes
Each cable contains the maximum amount of tapes.
Competitors: 1-sided ply tape allows for water to immerse through the cable and won’t flush it out.
Why is Aquaseal the better choice?
A single ply tape has the potential to wash away, while 2-ply tape contains and maintains the absorption rate at a particular point and the communications will not be interrupted.
What is the difference between In-conduit (AQC) and Direct Burial (AQ):
In-conduit (AQC): Any low-voltage cable with a gauge size of less than 18 will not pass the UL crush test, therefore these types of cables are required to be put into conduit if they will be installed in the ground.
Direct Burial (AQ): A nylon coating is extruded (not hydroscopic) over the PVC compound. This makes the conductors abrasive and resistant to water passing through it. Most PVCs are hydroscopic and will let water filter through it to help with other electrical and mechanical factors. The nylon also acts as a stiffening agent and will not allow the conductors to crush one another during the crush test procedure (Direct Burial test).
by http://www.fiber-mart.comIn some situations, where moisture or direct sunlight may be an issue, you need more than a standard Low Voltage Cable. Those situations are tailor made for West Penn Wire’s line of Aquaseal cables. Aquaseal has a strong history of use for applications where you need to run cable from one building to another either via direct burial or in-condiut and with Aquaseal there is no need to transition once you go back inside as they are suitable for both outdoor and indoor applications. As with all of the quality cables from West Penn Wire; the Aquaseal line maintains the full host of applicable UL ratings. 1) How do I use these cables? Good Question. Aquaseal Low voltage cables can be run from one building to another or inside of the same building whenever there is the potential for a wet environment. Aquaseal can be run via either direct burial (AQ Line) or inside conduit (AQC Line) – to suit the particulars of your installation. 2. What are the benefit to these cables? Aquaseal cables have a water blocking 2-ply tape and a jacket that resists sunlight and moisture. This allows the cables to expand within the jacket with an exceptional swell height, making the cable ideally suited for any type of wet location signal transmission. They hold a (SAP) Super Absorbent Polymer to soak up and trap any type of water that could affect the cable and have maximum tape for more protection. 3. What can these cables be used for? Aquseal cables are available in more than 40 constructions to meet any specific requirements.

AQ products are for direct burial applications while AQC cables are used for any in-conduit application.
by http://www.fiber-mart.comFiber Optic Cable are composed of fine hair-like glass fibers and messages are transmitted by sending light beams down the thin strands of glass through a shielded cable. Fiber Optics Cables are comprised of three main areas: 1) Core: Designed as the light carrier of the optical fiber. It is made from a doped glass(Silica).The silica material of the core allows the light signals to be carried efficiently and effectively across the fiber. 2) Cladding: It is made up from a different type of silica and surrounds the core. The glass of the cladding is made to contain the light within the core. 3) Plastic Coating: This piece surrounds the Cladding and acts as a protector for the glass. It is normally clear (color), but for all Outdoor cables the coating is color coded to help identify the individual fibers. The coating has to be removed to connect the fiber to a connector or splice. Bandwidth Investing in Fiber Optic Cables can significantly increase any businesses bandwidth compared to the transmission of data over the standard Copper Cable. The high frequency ranges they are able to carry exceed even the highest frequencies of any standard copper wire. Also, the speed of messages does not decrease as more demands are added onto the network when using Fiber Optics. Security Due to the higher demand for secure connections Fiber Optics Cables are a cost-effective way of adding an additional layer of security to any business. Copper Cables can easily be accessed by connecting taps to any line to pick up on the electronic signals, however, tapping Fiber Optics Cables is much more difficult. Energy Efficient The light waves that are transmitted through glass or plastic threads (fibers) use much less energy than data signals sent through metal conductors of Copper Cables. Easy Installations/Testing Fiber Optics Cables provide a light weight variation thus, makes terminating the cables more simplified. Also, testing a Fiber Optic Cable is as easy as sending a beam of light from one end to the other. In order to make installations easier for Fiber Optics, West Penn Wire also provides cabling, installation kits, fiber optics assemblies, fiber optics cassettes and cable management solution. Weight and Strength Fiber Optic Cable is also designed to be much thinner and lighter with pull tensions being much greater than those of most Copper Cables. For Example: 6-Fiber Cable: 300 lbs.RG6 Coaxial Cable: 55 lbs.Category 5E Cable: 25 lbs.Variety of Applications: Fiber Optics is also available for numerous applications, which are included but not limited to: TelecommunicationHigh bandwidth DataVideo signalingLong distance CCTVCommunication between fire alarm panelsand much more!
by http://www.fiber-mart.comFiber Optic connectors are definitely distinctive compared to the traditional copper cable connectors. Instead of the metal-to-metal contact, fiber optic connectors need to align microscopic glass fibers in order for the communication data to carry efficiently. Each connector contains three key components: Ferrule, Connector Body and Coupling Mechanism. The ferrule is the thin structure that holds the glass fiber in place and they are generally made of ceramic, metal or plastic. The connector body is what holds the ferrule in place and allows it to attach to the members within the cable fiber. A coupling mechanism which essentially holds the connector while it is linked to another device. It may contain a clip or bayonet nut depending on the connector type. Now, let’s look at some popular connectors and what they are used for within networking applications: SC Connector-(also known as the square connector) this type of connector contains a push-pull motion, snap-in connector with a spring loaded 2.5 mm ceramic ferrule to hold a single fiber. This connector is also the second most popular connector due to its method of maintaining applications. It can be used with either single-mode or multimode fiber optic cabling. LC Connector- this connector uses a 1.255 mm ferrule (half the size of the SC) and contains the standard ceramic ferrule. This connector is also a push-pull connector (similar to the SC) and utilizes a latch locking tab and can easily be terminated. ST Connector- (also known as a straight tip connector) this connector contains rounds ceramic ferrule, with bayonet mount locking features,enclosing a twist lock and a 2.5 mm keyed ferrule. This type of connector can be used with either single-mode or multimode fiber optic cabling.
by http://www.fiber-mart.comFiber optic cable has the ability to provide any business with safe, fast installations with higher bandwidth frequencies. In order to understand what fiber optic cable can do for your business or home, it’s important to understand the basic construction. Core- this is the very center of the cable and the light is guided down through by light transmission. The core is a single strand of glass that is measured in microns (µm). The larger the core, the more light the cable can carry. Sizes of the core: 8μm (8.3 or 9μm) Single Mode50μm – Mulit-mode62.5μm – Multi-modeCladding- this is a thin layer of glass that surrounds the core and serves to contain the light within the core. The cladding has a different index of refraction than the core so the light waves that are re-directed back into the core allow for continuous light transmission within the fiber. Size of the cladding:125 µm.Coating- This surrounds the cladding and acts as a protector for the glass. The coating is normally clear, but for all Outdoor cables the coating is color coded to help identify the individual fibers. This needs to be removed to connect the fiber to the connector or splice. Size of coating:250µmJacket- the cable jacket works along with the fibers to provide strength, signal integrity and overall protection of the fiber. There a variety of jacket materials that are used in the fiber cable construction. Environmental parameters that need to be considered upon installation are: temperature, chemical reaction, sunlight, mechanical and abrasion resistance.

by http://www.fiber-mart.comIn the past ten years, the traffic volume on China Telecom’s backbone networks has been growing at an astonishing rate of 47% per year. This poses a range of challenges to equipment investment, equipment room construction, power consumption and loading, and system operations. In an attempt to address some of these challenges, China Telecom is shifting from All-Optical Network 1.0 to All-Optical Network 2.0. The company plans to build a brand new network in line with its CTNet 2025 strategy through interconnection at the optical layer. The new network would be based on an “integrated, concise, agile and open” architecture and lay a solid foundation for future services such as 5G and cloud services. Project IntroductionChina Telecom had good reasoning behind choosing the middle and lower region of the Yangtze River to pilot its All-Optical Network 2.0 project. The region holds 25% of China’s population and 30% of its GDP. It boasts a vibrant and innovative economy with a fast-growing data center industry. The region is also home to some of the world’s most prominent Internet companies, those of which produce countless new Internet applications every year. SolutionIn 2017, China Telecom built a massive WDM ASON backbone network at 21 nodes throughout Jiangsu, Zhejiang, Shanghai, Hubei, Anhui and Jiangxi. 348 100G WDM links were planned in the preliminary stage, which will eventually be able to support 200G/400G in the future. Through full-mesh networking, China Telecom deployed the first All-Optical Network 2.0 backbone network in China. It differs from the previous All-Optical Network 1.0 in the following aspects: 1.From independent, separate chain topology to full-mesh networking.The full-mesh network topology creates the shortest service, protection, and recovery routes, allowing for one-hop transmission for services and E2E latency lower than 15 ms to meet CTNet2025 latency requirements. Furthermore, network security was greatly enhanced and fault recovery time significantly shortened. 2.From electric switching nodes to all-optical switching nodes.21 ROADMs were deployed to create intelligent optical nodes, which will eventually become the optical cross-connect (OXC). This cut construction costs, power consumption, and equipment room sizes of network nodes by 30%—50%. 3.From manual to smart operations.Full-mesh networks provide the interconnection basis for intelligent operations. Intelligent resource scheduling and on-demand bandwidth and latency can be realized via dynamic path selection at the optical layer and TSDN-oriented networks. In reference to the new initiative, Wei Leping, Deputy Director of the Science and Technology Committee of the Ministry of Industry and Information Technology, and Director of the Science and Technology Committee of China Telecom, stated, “The dynamic interconnection of the first ROADM backbone network in China initializes the strategic upgrade from electrical nodes to all-optical nodes and from point-to-point links to optical-layer mesh networking. This not only breaks the electrical bottlenecks of network node capacities, but also symbolizes the transition from All-Optical Network 1.0 to the new era of All-Optical Network 2.0. This is also a key step in the evolution towards China Telecom’s integrated, concise, agile and open CTNet2025 network reconstruction mission. It not only brings transformation at all layers of the transport network, but also promotes prosperity in related industries.”
