Question 1

What are the core optical and electrical specifications, power metrics, and transceiver compatibilities of the Huawei H802GPFD board?

Accepted Answer

The Huawei H802GPFD is a high-density 16-port GPON OLT line card conforming to ITU-T G.984.x standards. It delivers a downstream line rate of 2.488 Gbps (1490nm) and upstream of 1.244 Gbps (1310nm). Featuring 16 standard SFP cages, it supports GPON Class B+ (28dB optical power budget, Tx +1.5 to +5dBm, Rx sensitivity -28dBm), Class C+ (32dB budget, Tx +3 to +7dBm, Rx sensitivity -32dBm), and Class C++ (up to 35dB budget) SFP transceivers. The board supports up to a 1:128 split ratio with a standard 20km reach, extending up to 40km under lower split ratios. Electrically, it is highly energy-efficient with a static power draw of approximately 40W and a maximum full-load operational consumption of 73W.

Question 2

What is the chassis and control board compatibility for the H802GPFD, and can it coexist with legacy boards in the SmartAX MA5600T series?

Accepted Answer

The H802GPFD is natively compatible with Huawei SmartAX MA5680T (16 service slots), MA5683T (6 service slots), and MA5608T (2 service slots) subracks. To fully utilize its switching fabric without line-rate blocking, it requires GE/10GE backplane bus connectivity, pairing ideally with SCUN, SCUK, or MCUD/MCUD1 control boards. The board supports seamless coexistence in the same chassis with legacy 8-port GPON boards (GPBD), EPON boards (EPBD), and next-gen 10G GPON boards (XG-PON/XGS-PON). It fully incorporates hot-swappable protection circuitry, load-balancing, and inrush-current suppression, allowing live hardware maintenance without network downtime.

Question 3

How does the H802GPFD ensure high operational reliability and thermal resilience under extreme environmental conditions?

Accepted Answer

Engineered for high carrier-grade reliability, the H802GPFD operates across an industrial temperature range of -40°C to +65°C and relative humidity of 5% to 95% (non-condensing), complying with ETSI EN 300 019-1-3. Thermal management is optimized through specialized airflow-diverting heat sinks paired with intelligent chassis fan trays to eliminate hot spots. It integrates onboard TVS surge suppression and transient overvoltage/overcurrent protection matching ITU-T K.20 carrier standards. Furthermore, it supports live Digital Diagnostic Monitoring (DDM/RSSI), Type B/Type C optical protection switching, and automatic backplane bus failover, yielding an MTBF exceeding 450,000 hours.
