GCOB Fiberhome 16 Ports GPON Service Board

GCOB 16 Ports GPON Board - Fiberhome Service Card
Fiberhome Service Card GCOB 16 Ports GPON Board

GCOB Basic principle introduction:
Control module to complete the single board software loading, operation control, management and other functions.
Exchange module to achieve the convergence of 16 GPON port signals.
Interface module to realize the mutual conversion between GPON optical signal and Ethernet message.
The power supply module provides a working power supply for each function module in a single board.
