:: What are fiber optic loopback modules (fiber loopback)?

Fiber Optic Loopback modules are also called optical loopback adapters. There are LC loopback modules, SC loopback modules and other types.

They are designed for testing, engineering and the burn-in stage of boards or other equipment. Optical loopback adapters provide system test engineers a simple but effective way of testing the transmission capability and the receiver sensitivity of network equipment.

:: How to use:

One connector is plugged into the output port, while the other is plugged into the input port of the equipment.

:: Other Information

Fiber Optic Loopbacks are designed to provide return patch for a fiber optic signal. They are used for fiber optic testing applications or network restorations.

When used in testing applications, loopback signals are used for diagnosing problems. The best practice is to send a loopback test to network equipment, one at a time for isolating the problem.

Fiber optic loopback modules are made with a variety of fiber cable jacket types and cable diameters. We provide fiber optic loopbacks according to industry standard, all products are fully tested before shipping.

Fiber optic loopbacks are designed in a compact footprint. They are compliant with fast Ethernet, fiber channel, ATM and Gigabit Ethernet. Common fiber optic loopbacks types are: SC fiber optic loopback, FC fiber optic loopback, LC fiber optic loopback, MT-RJ fiber optic loopback.

Fiber Optic Loopback Specifications:

Insertion loss: Less than 0.2dB
Exchangeability = 0.2 (500 cycle passed)
Operating temperature range: Less than 0.2 dB ( -40 to +80°C)
