Fiber Loopbacks

Fiber Loopbacks

eFiberTools offers 62.5/125, 50/125 Multimode and 9/125 Single mode fiber optical loopback cables for testing in a wide range of applications. Our optical fiber loopbacks are each tested prior to shipping to guaratee the highest quality.

Fiber Optic Loopbacks are used for isolating and testing both transmitter and receiver channels of optical network equipment components. They are designed for single mode (9µm) and multimode (50µm /62.5µm) fiber optic connectors, equipment testing, self-testing optical networks, diagnostics and measurement applications.

There are several types of fiber loopback cables, such as LC, SC, FC, MTRJ.

eFiberTools stock loopbacks with precision terminaton and feature extremely low loss characteristics for transparent operation in the test environment and in form of cable and module types.

10G OM3, Singlemode and Multimode fiber optic loopback modules are available.​​​​​​​

Fiber Optic Loopbacks are typically used for testing the transmission capability and receiver sensitivity of network equipment. They are also known also as loopback adapters, loopback cables, loopback plugs or fiber optic loopback modules (with dual fiber optic connectors)

High performance in optical systems is due to precision ceramic ferrule. Loopbacks are an important part of troubleshooting in laboratories and manufacturing environments.Loopback Diagram

Fiber loopback cables or plugs offer a simple way of testing the optical transmission and receiver sensitivity of fiber network equipment.

The loopback plug tests to see if the router has any faults, and if not then then the problem exists elsewhere on the line.

To troubleshoot a serial line the best way is to perform loopback tests. Loopback tests allow you to isolate the circuit, and where necessary to test them individually.

Tests start at the channel service unit/data service unit (CSU/DSU) on the customer premises then move to the telco or provider. Two kinds of loopback tests on the serial link are software loopbacks and hardware plug loopbacks.

Internal or external CSU/DSU, you can do both software and hardware loopbacks back towards the router. Software local loopbacks are usually conducted with a Cisco IOS configuration command, or with a loopback button for some CSU/DSUs
