Light signal fiber amplification LA5300 is used in span of 50－90km.
1.Unique, advanced and cascaded DCM module design can greatly reduce the degradation of CNR and CSO in 1550nm fiber transmission system ,which is caused by DCM loss.
2. Small signal amplifier can upgrade output power of standard fiber amplifier to keep well CNR index.
3. Design of creative DC fiber amplifier overcomes the problem of large loss of traditional DC technology and realizes zero loss of DC in relay point to greatly increase the function index of CNR and CSO of network..
