Q: How does the H802A2EF2 perform regarding SmartAX chassis interoperability, mixed-slot expansion, and Ethernet OAM capabilities?

The H802A2EF2 board offers native interoperability with Huawei SmartAX MA5680T, MA5683T, and MA5608T chassis across mainstream control units such as SCUN, SCUK, and MCUD. It supports full hot-swapping and can coexist with GPON (GPBD/GPFD), XG(S)-PON, and Gigabit Ethernet interface boards within the same subrack, backed by centralized hardware QoS and flexible VLAN/QinQ mapping. Equipped with an on-board hardware-level Carrier Ethernet OAM engine, the H802A2EF2 complies with IEEE 802.3ah (EFM) and IEEE 802.1ag (CFM) standards, enabling real-time link performance monitoring, remote loopback testing, and millisecond-level fault demarcation.

Q: What are the environmental tolerance, surge suppression, and industrial reliability specifications of the Huawei H802A2EF2?

Engineered for harsh deployments, the H802A2EF2 operates reliably across an extended industrial temperature range of -40°C to +65°C (with -25°C cold-start capability) and 5% to 95% non-condensing relative humidity, making it ideal for outdoor telecom cabinets and unconditioned remote shelters. The board complies with ITU-T K.20 carrier-grade surge withstand requirements and features integrated ESD protection (±6kV contact, ±8kV air discharge). Its aerodynamic layout is strictly calibrated to the forced-air thermal profile of SmartAX fan units, achieving a carrier-grade MTBF exceeding 150,000 operational hours.

Question 1

What are the core electrical, optical, and transmission specifications of the Huawei H802A2EF2 Fast Ethernet board?

Accepted Answer

The Huawei H802A2EF2 (SKU: HW-OLT-H802A2EF2-FE) is an industrial-grade high-density Fast Ethernet optical interface board for SmartAX OLTs. It operates at a typical power consumption of under 30W, fed by the standard -48V/-60V DC chassis backplane bus. Featuring multi-port SFP cages, it supports 100BASE-FX, 100BASE-LX/ZX, and single-fiber BiDi transceivers across 1310nm, 1550nm, and 1490nm/1310nm wavelengths, delivering reliable point-to-point transmission spans of 2km, 10km, 20km, and up to 40km. The board provides non-blocking wire-speed L2 packet forwarding with ultra-low backplane switching latency (<20μs), optimized for carrier lease-line access and mission-critical enterprise backhaul.
