by Key Differences Between GPON SFP Class B+ and C+
The Key Differences Between GPON SFP Class B+ and C+ are their TX power and RX Sensitive.
Class B+ OLT transceiver: TX power 1.5~5db, RX sensitive -28db. Class B+ ONU transceiver: : TX power 0.5~5db, RX sensitive -27db.
Class C+ OLT transceiver: TX power 3~7db, RX sensitive -32db. Class C+ ONU transceiver: : TX power 0.5~5db, RX sensitive -30db.
When you configure the MA5683T, MA5680T, MA5600T, MA5608T, MA5603T… have the the confuse: what is The Key Differences Between GPON SFP Class B+ and Class C+ transceiver? Here we will solve the problem:

Hi! I am Shahed. Currently working as a Network Engineer. I want to build up my carrier in Networking field.
Follow Me:
Is B+ SFP in gpon OLT compatible with C+ ONU? Will it register?
yes, it is register.
Hi,usually I was using pon sfp modules for my epon OLT,when I tried with normal 1490/1310 sfp,found it is working with onu.Any pblm if use this way ?
Can we use C+ SFP in olt compatible with B+ ONU?
Yes possible.
Hi, good morning
how acn i know the launched power with out use the CLI command in olt? what equipment i should use? what is the messurement in that equipment , minimun 1,5 dbs ?
thnks in advance
For 0/0/0 PON port:
interface gpon 0/0
display port state 0
Hi Shahed, this is only aplicable to GPON and not for GEPON really??
Thanks in advance.
