Question 1

What are the optical/electrical parameters, split ratio, and power consumption of the Huawei H805GPUF 16-port GPON board?

Accepted Answer

The Huawei H805GPUF line card features 16 standard GPON SFP ports adhering to ITU-T G.984.x standards, delivering downstream 2.488 Gbps and upstream 1.244 Gbps line-rate transmission. Supporting up to a 1:128 optical split ratio per port, a single board achieves a maximum capacity of 2048 ONT subscribers. Compatible with Class B+, C+, and C++ GPON SFP optical transceivers, it provides optical budgets of 28.5dB, 32dB, and 35dB respectively, facilitating transmission distances of 20km to 40km. The typical power consumption is engineered at approximately 55W (idle at ~25W), integrating dynamic energy-saving algorithms and automated idle-port shutdown to effectively reduce data center PUE.

Question 2

What hardware-grade protections does the H805GPUF incorporate for industrial temperature tolerance, surge immunity, and reliability?

Accepted Answer

Engineered for rugged telecom environments, the H805GPUF supports an operating temperature range of -40°C to +65°C and relative humidity of 5% to 95% (non-condensing). The PCB utilizes controlled impedance routing and protective conformal coating to guard against airborne dust, humidity, and salt spray. Power inputs and interface lines comply with ITU-T K.20/K.27 lightning protection and surge immunity standards (common mode 6kV, differential mode 4kV). Featuring isolated DC-DC step-down modules and an optimized thermal airflow design, it delivers balanced heat dissipation under 100% full-slot traffic, achieving an MTBF exceeding 100,000 hours.

Question 3

According to on-site engineering specifications, what are the mandatory operational requirements and protection standards for electrical connections and cabling?

Accepted Answer

According to original factory manual specifications, electrical connections and cabling must strictly adhere to the following: 1. Live-line installation or removal of cables is strictly prohibited. 2. When performing electrical connections, personnel must not wear conductive objects such as watches, bracelets, or rings; protective gloves are recommended. 3. Insulated tools must be used for electrical connections, and exposed sections of terminals must be adequately insulated. 4. Cable cross-sectional areas must match the actual load. Cable coloring must comply with local power grid engineering codes; black cables must be selected if non-standard colors are used. 5. When connecting battery packs in series, batteries must be of the same brand, model, specification, and manufacturing batch/time; short-circuiting batteries in any manner during operation is strictly prohibited.
