APON,BPON,EPONandGPON
APON (ATM PON) was the first passive optical network and uses ATM for transport. BPON (Broadband PON) includes APON, Ethernet and video transports. GPON (Gigabit PON), which uses the SONET GPF frame, is designed to be efficient for packets as well as TDM. BPON and GPON are the ITU-T G.983 and G.984 standards respectively. EPON is the IEEE Ethernet standard for PONs.
What should I pay attention to when choosing the optoelectronic module?
1. The compatibility of the optoelectronic module
2. The transmission rate and distance of the optoelectronic module
3. The operating temperature of the optoelectronic module, the general commercial temperature is 0~70℃, industrial temperature is -45~80℃;
4. The service life of the optoelectronic module; In addition, the brand of the module is also very important, which is related to the after-sales service.
