GPON SFP
The GPON OLT Transceiver is designed for Gigabit-capable Passive Optical Network （GPON ） transmission. The module incorporates 1490nm DFB continuous-mode transmitter and 1310nm burst-mode APD receiver.
The transmitter section uses a high efficience 1490nm DFB laser and an integrated laser driver which is desigened to be class-1 eye safty under any single fault. The laser driver includes APC and temperature compensation functions, which are used for keeping the launch optical power and extinction ratio constant over temperature and aging.
The receiver section uses an integrated APD detector and burst mode preamplifier mounted together. To provide fast settling time with immunity to long streams of Consecutive Identical Digits(CID), the receiver requires a reset signal provided by the media access controller(MAC). The receiver has fast SD function,the rising time is about 5ns, when reset signal arrived, the SD signal will be turned to low, and the noise in the guard time will be squelched.
The following list is our GPON OLT SFP modules . If you don't know how to choose,please feel free to contact us.
