MPO Loopback Attenuator
The MPO Loopback Attenuator is a high-performance device designed for fiber optic network testing and validation. It integrates loopback functionality with signal attenuation, effectively simulating real network environments to ensure the stability of optical transceivers and fiber links. Available in both singlemode and multimode versions, it supports 40G, 100G, and higher-speed optical network systems. Its compact design is ideal for high-density cabling environments, such as data centers and
Fiber optic loopback attenuator incorporates two fiber optic connectors which are plugged into the
output and input port of the equipment respectively. Therefore, fiber loopback attenuator can
be classified by the connector types, such as LC, SC, MPO and MTP. These fiber optic
loopback connectors are compliant with IEC, TIA/EIA specifications.
The MTP/MPO fiber optic loopback attenuator is one of the most popular loopbacks attenuator. support the test of
transceivers featuring MTP/MPO interface. 12fibers, 16fiber, and 24fibers or more can be
chosen, and also can be defined the cable Polarity by customize, They can comply with low
insertion loss, low back reflection and high precision alignment.
