Copper ToolsIntroduction, classification and application of Optical Fiber Loopback
Optical fiber loopback (Lookback), also known as optical module self-loop test loop, is used to test the signal backhaul in the system or network system, and can detect various potential abnormalities in the network link by returning the signal (mainly connecting the transmitter of the TX to the receiving side of the RX in pairs). The optical signal in the optical fiber will reduce the optical power due to absorption, scattering and other reasons during the transmission process, and the optical fiber loss has an important impact on the communication distance.
Because optical fiber connectors are divided into LC, SC, FC, ST, MU, MT, MPO/MTP, etc., there are also very corresponding types of optical fiber loopers.
MTP/MPO fiber optic looper
The MTP/MPO loopback contains an MPO loopback jumper, which threads both ends of the optical fiber into an MTP/MPO connector, so that the optical path is in the same connector, and the signal is returned to it without changing the signal or repeating the signal. It can provide an effective solution to test the transmitting ability and reception sensitivity of network equipment, especially in 40/100G network communication, various potential phenomena can be located through backhaul signals, so as to achieve effective testing and evaluation of individual components or interfaces and networks on paired fiber networks.

Troubleshooting
Accommodates 8-, 12-, and 24-fiber MTP/MPO connectors, as well as several fiber configurations, to accommodate the ports under test. The streamlined, rugged housing design provides greater stability and reliability.
Other optical fiber loopers such as LC, SC, FC, etc
Depending on the connector, the circuit breaker also includes a variety of types such as LC, SC, FC, etc. Available in single and multi-mode options, end PC or APC. With 40G/100G optical transceivers, it is used for optical fiber testing, network repair, and equipment fault diagnosis, which is an ideal choice for testing transmit optical power and receiving sensitivity.
