Category: Why & What

you can know why this happend or what is about something.

Why on earth do we need to choose active optical cable(AOC)?

AOCs bond the fiber connection inside the transceiver end, creating a complete cable assembly much like a DAC cable, only with a 3-200-meter reach capability.

What is an AOC? 

—Here is the brief definition of AOC:

Optical transceivers convert electrical data signals into blinking laser light which is then transmitted over an optical fiber. Optical transceivers have an optical connector to disconnect the fiber from the transceiver. AOCs bond the fiber connection inside the transceiver end, creating a complete cable assembly much like a DAC cable, only with a 3-200-meter reach capability. AOCs main benefit is the very long reach of optical technology, while acting like a simple, “plug & play” copper cable.Active Optical Cable assemblies have been designed to support multiple protocols. Most of them are compliant with SFP+ Ethernet and InfiniBand electrical. Here is what a typical 40 Gb/s QSFP+ (Quad Small Form-Factor Pluggable Plus) AOC supports.

Mainly, active optical cable (AOC) assemblies were invented to replace copper technology in data centers and high performance computing (HPC) applications. As we know, copper passive twinax cable is heavy and bulky, making it difficult to physically manage the datacenter. And due to the nature of electrical signals, electromagnetic interference (EMI) limits copper’s performance and reliability. Though there are so many disadvantages of copper cable, at that time, it is the main stream while the idea of AOC cables almost seems too good to be true. However, the advantages of AOC cables make the predecessors look obsolete and unsophisticated, and changes the limitation of copper passive twinax cable as well as playing an important role in high speed data transmission. Nowadays, a variety of active optical cable have been launched in the market, such as 10G SFP+ AOC, 40G QSFP+ to QSFP+ AOC,40G QSFP+ to 4 SFP+ breakout AOC ,40G QSFP+ to 8xLC breakout AOCs.

What are AOC Features and Advantages?

Compared to less expensive DAC cables, AOC offer:

  • Longer reach capability than DAC 3-7 meter limits;
  • 3m – 100-meters multi-mode technology;
  • 100-200 meters with single-mode, Silicon Photonics;
  • Lower weight, thinner cable and bend radius enabling increased airflow cooling and easier system maintenance.

Compared to more expensive optical transceivers, AOC offer:

  • Dramatically lower priced solution than two optical transceivers and connectorized fiber based links;
  • Lower power consumption at 2.2 Watts versus up to 4.5 Watts for optical transceivers (4-channel);
  • Lower operational and maintenance cost.

 

Fiber-Mart supplies various kinds of high speed interconnect AOC cable assemblies including 10G SFP+ AOC, 40G QSFP+ AOC Cables,100G QSFP28 AOC, 120G CXP AOC Cables. For more information, you can visit web Fiber-MART.COM.if you have something interest, pls feel free to contact us：service@fiber-mart.com

Waterproof Fiber Cables

Waterproof fiber optic patch cables are designed to fit for outdoor connection applications. The strong PU jacket and singlemode APC armored structure of cable provide 1Gigabit data transfer speeds in high bandwidth application.

With the development of modern communication industry, optical fiber has become an increasingly important communication line medium because of its advantages such as wide frequency band, low loss, long transmission distance and anti-electromagnetic interference. In metropolitan area networks and campus networks, the application of outdoor optical cables is becoming more and more common. For outdoor optical cables, in addition to bandwidth, loss, and other transmission performance, another very important technical indicator is the optical cable’s water blocking performance.

Waterproof fiber optic patch cables are designed to fit for outdoor connection applications. The strong PU jacket and singlemode APC armored structure of cable provide 1Gigabit data transfer speeds in high bandwidth application, up to 5 times faster than standard 9/125um fiber patch cable. What’s more, it’s IP67MPO cable connectors have an extremely rugged, protective rubber coating with integral anti-kink strain-relief boot and a rubber-coated, metal, latching cap, attached by a steel lanyard. When mated or capped, the connection is environmentally sealed up to IP65. They can resist high temperature and suit to use in harsh environment, and ideal for use in a variety of applications, including Fiber to the Antenna (FTTA) and Fiber to the Home(FTTH).

Like choosing any other fiber optic patch cables, the connector type, fiber count, fiber type (single-mode or multimode), polish type, cable length and cable jacket are factors that should be considered as well. When buying waterproof fiber optic patch cords, the IP (International Protection or Ingress Protection) rating is an important parameter. Knowing the IP code can help you find your wanted waterproof cable.

 

IP rating system is a classification showing the degrees of protection from solid objects and liquids. IP rating codes do not include hyphens or spaces, and consist of the letters IP followed by one or two figures. The first number refers to the degree of protection against the entry of foreign solid objects, such as dust. These protection levels range from 0 to 6. The second number of the IP code refers to the degrees of protection against moisture/liquids, which are raging from 0 to 8. The first and second number of the IP code can be replaced by the letter “6″or7”.Norally called IP67.

There are two types of IP67MPO weatherproof connector: IP67MPO plug (with locating pins) and IP67MPO Socket (without locating pins), the plug of one cable and the socket of the other cable can be connected to extend the cable length. See blow:
