Service Bboards

H805GPBD Board

H805GPBD is a 8-port GPON OLT Interface Board. It works with the optical network terminal (ONT) to provide GPON access service.

The H805GPBD board supports the following functions:

Eight GPON SFP ports A maximum of 1:128 split ratio Class B+ and Class C+ optical modules Received signal strength indicator (RSSI) detection and controlled optical signal transmission of the optical module ONU-based shaping Optical performance monitor (OPM) Automatic power shutdown in case of a high temperature   

Control Boards

H801SCUN Board

The H801SCUN board is a Super Control Unit Board. It is the core of the system control and service switching and aggregation. The H801SCUN board can also function as the management and control core of the integrated network management system (NMS). It communicates with service boards about the key management and control information through the master/slave serial port and inband GE/10GE channel. In this manner, the H801SCUN board configures, manages, and controls the device, and also implements the simple route protocol functions.

The H801SCUN board supports the following functions:

System control and management unit Local and remote maintenance Active/standby switchover Load balancing GE or 10GE channel to the service board Environmental monitoring parameters Four SFP GE ports for upstream transmission or cascading 

Upstream Interface Boards

H801GICF Board

The H801GICF board is a 2-port GE Optical Interface Card, providing upstream or cascading optical ports.

The H801GICF board supports the following functions:

Upstream transmission or cascading Two SFP GE ports 

Power Boards

H801PRTE Board

The H801PRTE is a Connect Power Board. It leads in the -48 V DC power supply for the device.

The H801PRTE board supports the following functions:

One -48 V power input Filtering and current-limiting for the power input port Under-voltage detection, detection of whether the input power exists, and fault detection Combined reporting of the protection alarm and board online signal ALARM indicator
