12 Fibers MTP OM3 Fiber Optic Loopback Module / Cable
Zion Product Information
Zion Code: ZCM2126HXA1
Description: 12F MTP OM3 Fiber Optic Loopback Module / Cable
The MTP loopback contains MTP fiber optic cable configured in a loopback arrangement, with both ends terminated in an MTP connector to create a continuous light path within the same connector. This configuration enables testing of device launch capacity and receiving sensitivity, particularly in 40/100G network communications. By returning signals back to the source, it helps identify various network phenomena and facilitates effective testing and evaluation of individual components or interfaces within fiber optic networks.
Available in multiple optical fiber configurations accommodating 8-core, 12-core, and 24-core MTP connectors to match various test port requirements. The 12F MTP Fiber Loopback Module specifically allows verification and testing of transceivers featuring MTP interfaces for 40GBASE-SR4 QSFP+ or 100GBASE-SR4 devices.
MTP Loopback modules provide looped signals to test transmit and receiving functions, widely used within testing environments, especially in parallel optics 40G and 100G networks. Loopbacks connect Transceiver (TX) and Receiver (RX) positions of MTP transceiver interfaces and can facilitate insertion loss testing of optical network segments when connected to MTP trunks and patch leads.

Fiber Optic Loopback Testing
A loopback test involves sending a signal from a communication device and looping it back to the same device to verify proper functionality or troubleshoot defective network nodes. For fiber optic loopback testing, optical loopbacks verify the operational reliability of devices by routing the signal emitted from the transmit (Tx) end back to the receive (Rx) end of the same component.
Applications
Fiber optic loopback testing is commonly used for checking fiber optic transceivers. Since transceivers have separate ports for receiving and transmitting light signals, testing these ports is essential for maintenance. The testing process routes the laser signal from the transmitter port back to the receiver port, then compares transmitted and received patterns to ensure they are identical and error-free.
- Collocated with 40G or 100G MPO/MTP interface transceivers
- Used for testing transmission capability and receiver sensitivity of fiber optic network equipment
