Question 1

What are the core optical parameters, electrical power metrics, and splitting capacity of the Huawei H807GPBD board?

Accepted Answer

The Huawei H807GPBD (SKU: HW-OLT-H807GPBD-8P) is a carrier-grade 8-port GPON OLT line card fully compliant with ITU-T G.984.x standards. It features 8 standard SFP optical interfaces compatible with Class B+ (Tx power 1.5–5 dBm, sensitivity -28 dBm) and Class C+ (Tx power 3–7 dBm, sensitivity -32 dBm) transceivers, operating at 1490nm downstream (2.488 Gbps) and 1310nm upstream (1.244 Gbps) over a maximum 20 km reach. The board natively supports a 1:128 optical split ratio per port, enabling up to 1,024 FTTH subscribers per board. Electrically powered via backplane DC bus (-48V/-60V), the board features ultra-low power consumption—25W static and 45W under full traffic load—ensuring optimal energy efficiency and low thermal output in high-density OLT chassis deployments.

Question 2

What are the mandatory specifications and procedures for electrical wiring, monitoring signal interfaces, and cabling during installation and commissioning?

Accepted Answer

According to technical installation specifications: 1. Interface & Connection Sequence: Follow the defined sequence for connecting the protective ground (PE), AC input lines, working ground, DC output lines, and monitoring signal cables (including alarm input dry contacts). 2. Electrical Safety & Tooling: Live-line connection or disconnection of cables is strictly prohibited. Operators must not wear conductive objects (watches, bracelets, rings), must wear protective gloves, use insulated tools, and fully insulate exposed terminal areas. 3. Cable & Battery Requirements: Cable cross-sectional area must match the actual load and comply with local grid standards (black cables must be used for non-standard colors). Battery strings must consist of units with the identical brand, model, specification, and manufacturing batch, with short circuits strictly prohibited. Energy storage modules must avoid offline storage in a low SOC state (SOC≤5%) to prevent permanent over-discharge damage caused by ESMU static power consumption.

Question 3

What are the LED indicator acceptance criteria, voltage protection thresholds, and on-site troubleshooting procedures?

Accepted Answer

According to the user manual and commissioning guidelines: 1. LED Acceptance Criteria: The standard acceptance condition requires the RUN indicator to be steadily on with no red fault indicators active. During simulated mains failure and restoration tests, the battery operating state must switch properly, and the operating current deviation must be within ±2A. 2. Protection Thresholds: The low voltage alarm threshold is 47V/47.6V, the secondary load disconnection threshold is 46V/47V, and the battery disconnect threshold is 44V/46V. 3. Troubleshooting & Maintenance: If a red indicator or power anomaly occurs, check the ESM indicator state first. Verify whether prolonged power outages have caused storage in an over-discharged state (SOC≤5%, allowable storage limit: 30 days @ 25°C, 15 days @ 45°C; recharge immediately if expired). Always execute manual power-off on the ESM upon site commissioning to ensure entry into low-power sleep mode. Software upgrades must be performed under normal AC input by skilled personnel trained in energy-source hazard protection.
