General Details

SC Fiber Optic Loopback Module, Multimode Cable

A fiber loopback is a critical diagnostic tool for testing fiber optic networks. It tests the transmission capability and signal integrity of the network components such as transceivers, network cards, and network connections.

FOCONEC supplies a Multimode SC Fiber Optic Loopback Module, providing a return media for an optical signal, no matter whether the signal is for testing purposes or network restoration.

By creating a signal loop from a transmitter to a receiver within one SC loopback plug, it forms the optical link which allows testing of optical network segment by segment.

Similar to a regular fiber patch cord, our multimode SC fiber optic loopback is available in multimode OM1, OM2, OM3, or OM4 fiber. Each fiber loopback cable is functionally tested before delivery.

Fiber loopbacks are used in various applications:

  • Testing and troubleshooting network issues, verifying the operational integrity of network hardware.
  • System maintenance and diagnostics, ensuring that all optical network components are functioning optimally.
  • Bench testing of network equipment before deployment, ensuring that devices are fully operational and configured correctly.


  • Loopback module with SC connectors
  • Multimode 50/125, 62.5/125
  • RoHS compliant material used
  • Compact design, easy to use
  • Fully tested before delivery
  • Compatible with Fast Ethernet, Fiber Channel, ATM, and Gigabit Ethernet

There are different types of fiber loopback modules, often categorized by the type of fiber optic connector used, such as:

  • LC (Lucent Connector): A popular small form factor connector used in many applications.
  • SC (Standard Connector): A push-pull style connector used for its simplicity and durability.
  • MT-RJ (Mechanical Transfer-Registered Jack): A connector used mainly in multimode fiber applications and known for its compact size.
