【Main Parameters】Loopback tester are with LC-UPC connector plug and single-mode fiber; supports -20~70℃ operating temperature
【Operating Principle】 Pairwise connected TX transmitting face transmit the signal back to the RX receiver face to test and evaluate the elements or interfaces of the optical fiber network.
【Stable Signal Transmission】 the looper adopts A-level zirconium ceramic core, which is low insertion loss (≤0.3db) and low return loss ( ≥ 50db), high interchangeability (≤0.2db) and high repeatability (≤0.2db)
【Standard Size】 The product meets the dual fiber adapter size standard for easy and accurate plug and pull,which can work more than 1000 times.
【Widely Application】It can detect potential abnormalities by testing the signal return of optical system debugging, optical fiber communication system, CATV system, etc.
