Main Parameters Loopback tester are with LC Connector for APC end face 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 ( 0.3 db) and low return loss ( 60db), high interchangeability ( 0.2 db) and high repeatability ( 0.2 db) ^^ Standard size The product meets the dual fiber adapter size standard for easy and accurate plug and pullwhich 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.
