Huawei GPBD (GPON/EPON Business Board) Is The OLT Device in The GPON/EPON System

‌Huawei GPBD (GPON/EPON service board) is an OLT device in the GPON/EPON system, mainly used for small and medium-capacity access networks. ‌

Functions and uses

The functions and uses of Huawei GPBD optical access equipment are similar to those of Huawei MA5680T, and are mainly used to provide GPON and EPON access functions. Specifically, GPBD provides the following functions:

‌GPON access function‌: Through the GPON optical service access board (GPBD) of GPBD, the access function of the GPON interface can be realized, and multiple GPON interfaces can be supported.

‌EPON access function‌: Through the EPON optical service access board (EPBD), the access function of the EPON interface is provided, and multiple EPON interfaces are also supported.

‌Uplink function‌: Through the GE uplink optical interface board (GICF, X1CA, etc.), high-speed uplink transmission function is provided.

Hardware configuration and interface

The hardware configuration of Huawei GPBD includes multiple slots, as follows:

‌Service board slot‌: Slots 0 to 5 are configured with service boards, supporting GPON and EPON service access.

‌Main control board slot‌: Slots 6 to 7 are main control board slots, and two main control boards can be configured to achieve master-slave functions.

‌GIU uplink board slot‌: Slots 8 and 9 are equipped with GIU uplink boards.

‌Power board slot‌: Slots 10 and 11 are equipped with power boards.

‌General interface board slot‌: Slot 12 is equipped with a general interface board.

In addition, Huawei GPBD also provides a variety of interface types, including maintenance network port, serial port, environmental monitoring port, GE uplink optical interface, 10GE uplink optical interface, etc., to meet different network transmission requirements‌12.

Environmental parameters and power supply parameters

Huawei GPBD's environmental parameters include:

‌Working environment temperature‌: -30℃～+60℃

‌Working environment humidity‌: 5%RH～95%RH

‌Air pressure environment‌: 54kPa～106kPa

In terms of power supply parameters, Huawei GPBD's power interface board (PRTE) supplies power to the business frame to ensure stable operation of the equipment‌
