Optical loopback is used to test the transmitting ability and receiving sensitivity of optical fiber network communication equipment. At the same time, it is a stable and effective product for detecting system loop.
Fiber optic loopback tester is the most convenient way for transceiver maintenance and can be used for testing the transmission capability and receiver sensitivity of fiber optic network equipment.
Fiber Loopback Module is designed to provide a media of return patch for a fiber optic signal. Typically, it is used for fiber optic testing applications or network restorations. For the testing applications, the loopback signal is used for diagnosing a problem. Sending a loopback test to network equipment, one at a time, is a technique for isolating a problem. Fiber Loopback Module can provide an economical solution for many fiber optic test applications.
Fiber optic loopback tester is designed with a protective casing for the fiber optic cable, preventing bending or breakage and enhancing the adapter’s durability during tests.
SC Loopback adapters are used in testing SC interface products, LC loopback adapters are used in testing 10G or 40G or 100G LC/UPC interface transceivers.
