Fiber Optic Adapters – the Bridge between Fiber optic Connectors

by http://www.fiber-mart.com

Definition of Fiber Optic Adapter
Fiber optic adapter is a device used to connect two fiber optic connectors in the fiber optic cabling system. It seems like a bridge to connect the gap between two same styles connectors, even the different connectors. Due to its fuction, there is a specific situations of fiber optic adapter. If two fiber assemblies to be connected have the same style fiber connectors, it is called coupler. If the two fiber assemblies to be connected have different style connectors then we always call adapter. We can see an example in the following picture. The adapter connected ST connector to ST connector, both sides are the same style, in this time, we call coupler. Otherwise, we call adapter.

Types of Fiber Optic Adapter
According to the diversity of the fiber optic connectors, there are many types of fiber optic adapters. Adapters are available to join like connectors SC-to-SC, ST-to-ST, or FC-to-FC–and different styles of connectors. The latter devices are called hybrid adapters and are used, for instance, to join ST and SC connectors. We can see the following pictures to know more about different types of fiber optic adapters.
fiber-optic-adapter
How do Fiber Optic Adapters work?
As we known, the key to a fiber connection is the precise alignment of each fiber core, so traditional connection method, such as the soldering is defective. Inside each fiber optic adapter, there is the alignment sleeve. The aligment sleeve is the most critical component of a fiber optic adapter. Bronze sleeves are more durable but the precision is not as good as ceramic. Ceramic ferrules offer a more precise alignment, but they are somewhat less durable. Bronze alignment sleeves are commonly used in multimode applications where precision alignment is not as critical. The performance of the adapter, defined as how well it aligns two connector ferrules, is determined by the amount of spring force in, and the tolerances of, the split sleeve. It needs a very professional technology to make it a reality.

Guide To Fiber Optic Polishing

by http://www.fiber-mart.com

Optical fibers require end-surface treatment for proper light propagation and that includes polishing their ends. Polishing is essential for almost all glass-based fibers with cladding diameters larger than 200 microns. Furthermore, all fiber connectors require polishing. The process of fiber optic polishing can occur in the field or in a technical lab, it employs a range of tools and products used to create precision fits and finishes in the delicate glass ends.
There is typical fiber optic polisher for fiber optic polishing. Fiber Optic Polishing Machines are used to polish the end faces of fiber optic products (cables, connectors, adapters, etc.) in order to minimize signal losses due to scattering. Polishing machines can increase productivity by providing rapid polishing of many different connector styles.
When selecting a fiber polishing machine, there are several features to consider, including adjustable pressure, changeable holders, a timer, and the ability to request custom specifications. Most polishing machines do not offer the flexibility of speed adjustment. This is partially due to the fact that most users only need to handle one type of ferrule material such as zirconia. A slight speed variation does not have significant impact on connector polish result. However, a versatile polisher should have the capability to change speed according the ferrule and polishing film material.
The polishing job typically involves fusion splicer, among other network crimping tool and connectors are needed. It also requires 99% isopropyl alcohol, polishing (lapping) film and pad, a polishing puck, and epoxy or adhesive. Some technicians also find needle, syringe, and piano wire useful.
Several Different Polish Options On Fiber Connectors
The different polish of the fiber optic connector ferrules result in different performance of them, mainly on the back reflection (return loss). Generally, PC type is required at least 40dB return loss or higher, UPC is 50dB or higher, APC is 60dB or higher. (As we know, the higher the return loss, the better the performance). Insertion loss of them all should be less than at least 0.3dB, the lower the insertion loss the better the performance.
Things You Need To Mind During Fiber Optic Polishing
It is important not to dwell on any polishing film longer than necessary. Too much polishing can result in undesirable ferrule length, unnecessary polish film wear, and degraded polish finish due to particle accumulation. Make proper adjustments to the recommended polishing time in each step in case they are less than ideal.
Eye protection is always necessary to protect against powerful industrial lasers used in long-distance single-mode networks. Supporting tools may include a visual fault locater to troubleshoot fiber faults and breaks. A fiber-optic inspection microscope permits precision analysis of hair-fine fibers. Additionally, technicians rely upon jacket strippers, cutters, cable slitters, and fusion splicers.
Conclusion
Fiber polishing is a science but much like an art. The science of polishing is crystallized in a well designed machine while the art of polishing reside in the procedure and the continuous effort for improvement by the individual user. The procedure and the training are just as valuable as the polishing machine.

THE DIFFERENCE BETWEEN FUSION SPLICING, PATCH CONNECTIONS

by http://www.fiber-mart.com

Insertion loss is one of those fiber-optic challenges that follows all network engineers, no matter where they’re working. Whenever you have a connection of one fiber to another, you will incur insertion loss.
This is the ninth in a fiber-mart.com blog series, entitled The A-B-Cs of Cable Management.Our Product Manager defines insertion loss and demonstrates the difference between loss on patch connections and fiber splices.
Insertion loss and light budgets are problems every engineer works with and figures out solutions for.
Insertion loss, expressed in decibels (dB), is the loss of signal power resulting from the insertion of a device in a transmission line or optical fiber.
The increasing number of fiber connections on hyperscale fiber networks is pushing insertion loss into the priority zone for engineers.
More connections mean higher rates of insertion loss, and higher rates of insertion loss mean trouble on your network.
And then there’s the difference between patch connections and fusion splices.
FUSION SPLICING VS. PATCH CONNECTIONS
Patch connections will have increased insertion loss.
Typically, the loss for a patch connection ranges from 0.05dB to 0.2dB. This may seem like a large amount of signal loss, but patch connections carry the advantage of not being permanent. Technicians can use this advantage for:
Service
Troubleshooting
Cross-connections
Redundancy
These are great advantages, even though you have the larger amounts of insertion loss.
Fusion splice connections offer their own set of advantages. Instead of 0.05dB to 0.2dB of loss with a patch connection, a fusion splice normally incurs only between 0.05dB and 0.1dB of loss.
While you have the advantages of less loss with a fusion splice, there is one large drawback. The connection is permanent … well, sort of.
Yes, you can cut a splice and re-terminate in the field, but this is much more labor intensive than unplugging even the tiniest LC connector. Splicing has its place, but so does a patch connection.
SOLVE THE INSERTION LOSS PUZZLE ON YOUR NETWORK
Most modern telecom, enterprise, government or CATV networks have more than just patch and splice terminations to worry about.
Our customers deal with passive optical devices that incur insertion loss all over their networks. Telecom engineers worry about devices like splitters, CPRI monitoring and TAPs. CATV engineers face concerns about WDM devices and splitters.
These different networks employ devices that have inherent insertion loss.
As a technician or an engineer, it is your duty to work with your colleagues and suppliers to develop the loss budgets for your network. There are many ways you can reduce the loss in your network, such as:
1.Cleaning and maintaining your patch connection’s end faces
2.Using high-quality passive optical devices that have low insertion loss characteristics
3.Implementing ULL connectors that have substantially less theoretical insertion loss characteristics than standard connectors
4.Ensuring you are not creating situations where micro bends, micro fractures and macro bends can hurt your signal strength
At fiber-mart.com, we pride ourselves in our ability to work with our customers to provide high-quality solutions that will reduce the insertion loss of your network and pad your loss budgets. Our high-quality passive optical devices, cables with ULL connectors and our WaveTrax fiber raceway product line are all methods you can employ to reduce the amount of light loss in your network.

Brief Introduction of Fiber Optic Splitter

by http://www.fiber-mart.com

Fiber optic splitters are quite important in today’s optical network. Splitters can help users maximize the functionality of optical network circuits. A fiber optical splitter is a passive optical device that can split, or separate, an incident light beam into two or more light beams. These beams may or may not have the same optical power as the original beam. The outputs of a splitter can have various degrees of throughput. And that is very useful to decide whether the splitter is used for network monitoring or for a loss budget in a passive optical network (PON) architecture when designing optical networks. This article will give brief introduction of fiber optical splitter.
Two Types of Fiber Optic Splitter
There are two kinds of the most commonly used fiber optical splitters. And they are planar lightwave circuit (PLC) and fused biconical taper (FBT). PLC splitters (as shown in the following picture), from the name, it’s easy to find out that PLC splitter is based on planar lightwave circuit technology. It uses an optical splitter chip to divide the incoming signal into multiple outputs. It consists of three layers including a substrate, the waveguide, and the lid. The waveguide layer accepts the incoming optical signal and passes it to the outputs. FBT splitter is fused with a heat source similar to a fusion splice. Fibers are aligned in a group to create a specific location and length and will be fused with heat to meet the desired parameters such as insertion loss. Fused fibers are put in a V-shaped groove and fixed in a silica tube with a mix of epoxy and silica powder to get the proper heat.
Fiber Optical Split Ratios
Fiber optical splitters vary in numbers of inputs and outputs. The split ratios are based on the network use of fiber optical splitters. In a PON architecture, it uses splitters to split a single fiber into multiple fibers to feed as many as 64 end users. A typical split ratio in PON application is 1:32, or one in coming fiber split into 32 outputs.
Large split ratios like 1:32 or 1:64 are often found in some kind of housing. That’s because with so many fibers related to these splitters, a platform should be used to manage the splitter modules, patch modules, patch cables, etc. Most often a high-density fiber bay is required so that the splitters can be all placed in a distribution site or a PON enclosure. The PON cabinet plays a significant role in today’s applications since the space is so limited. When it comes to a high-density frame with varying split ratios and large number of patch cords, the distribution frame is critical for a good cable management.
Cost Saving in FTTx/PON Applications
As the city grows and subscribers increase, the network architect must deal with multiple distribution points and backhaul. To meet so many subscribers’ requirements, the flexibility in head-end locations, distribution points and split ratios becomes more significant. To network service provider, saving capital and operational costs is important.
On one side, fiber optical splitters can save fiber cost by reducing the fiber usage and that’s why they are so important in FTTx/PON networks. Using a single fiber to feed as many as 64 end users significantly reduces the fiber quantity. On the other side, the long-term operation costs can’t be ignored either in optical network splitter applications. That’s one of PON’s advantages. For example, it can decrease the power consumption.
Another way to save cost is to ease maintenance and increase the flexibility for smaller split ratios, which lead to more bandwidth per subscriber. For example, a service provider would likely need to split the optical terminal line (OLT) with a 1:2 splitter, and adjust the split ratios from there based on delivery to residential (1:32). These multiple split ratios can create flexibility in the network as long as the utilization of transport electronics such as OLT is concerned. Loss budget can be greatly influenced by the use of multiple splitters.
Conclusion
From the above content, to run a network architecture, the network success and cost should be paid attention. And fiber optical splitter is such a good device to increase the efficiency of optical infrastructure and save the capital and future operational cost.
