12F MTP MPO Female OM4 Loopback

OPTICO optical fiber MPO/MTP optical fiber loopback modules are widely used in test environments, especially in 40/100G network communications. This product is used for signal return in test systems or network systems, through return signals (mainly in pairs From the TX transmitting end to the receiving end of the RX, various potential abnormalities are located, so as to achieve effective testing and evaluation of individual components or interfaces and networks on the optical fiber network-including 40GBASE-SR4 QSFP+ or 100GBASE-SR10 CXP/ CFP Optical module.


Standard MTP connector

The new fiber optic ring is lighter and takes up less space

Each loopback module is equipped with a dust plug to effectively prevent external pollution


With 40G/100G optical module

Fiber test

Network repair

Diagnose equipment failure

Test the transmitted optical power and receiving sensitivity
