C320 C300 GPON PON BOARD (GTGH GTGO ETGH ETGH ETGO) 8/16 PORTS, WITH SFP PX20++

GTGH, GTGO, ETGH, and ETGO are all OLT service boards, primarily compatible with C300 and C320 series optical line terminals, and are core hardware components for FTTH/FTTB fiber optic network construction.

Core Parameters and Functional Differentiation:

GTGH: 16-port GPON service board, fully equipped with 16 GPON optical ports, supports C+ and C++ level optical modules, a single port can support a large number of user accesses, and is the mainstream board for operator broadband projects.

GTGO: 8-port GPON service board, fully equipped with 8 GPON optical ports, port density lower than GTGH, suitable for small to medium-scale broadband networking scenarios.

ETGH: 16-port EPON service board, fully equipped with 16 EPON optical ports, compatible with EPON-based fiber optic networks, mostly used for regional expansion of early EPON deployments.

ETGO: 8-port EPON service board, fully equipped with 8 EPON optical ports, port density lower, suitable for small to medium-scale EPON networking scenarios.

Important Notes:

Optical Module Matching: Prioritize versions with built-in C++ level optical modules. Their transmission distance and device capacity are significantly higher than ordinary C+ modules, avoiding additional costs associated with purchasing separate modules.

Version Verification: Confirm that the board hardware version is compatible with the existing OLT main control board firmware to avoid issues such as board registration failures and abnormal service deployment.

Power Consumption Planning: 16-port boards typically consume more power than 8-port boards. Verify the OLT chassis power supply capacity in advance to avoid insufficient power supply to the entire unit.
