Q: What is the chassis interoperability of this SFP+ module, and does it support rate auto-negotiation or mixed slot deployment?

Engineered with native Huawei EEPROM microcode, this transceiver integrates seamlessly with Huawei CloudEngine switches (CE6800/CE8800/CE12800), enterprise campus switches (S5700/S6730/S12700E), and NetEngine routing platforms (NE40E/NE8000). While it can be installed alongside standard 1G SFP (1000BASE-LX) optics within dual-rate SFP/SFP+ cages across the same line card, the transceiver operates at a fixed 10.3125 Gbps PHY clock and does not support automatic legacy 1.25 Gbps down-negotiation. It supports seamless hot-swapping, backed by multi-stage inrush current limiting circuitry and gold-plated edge connectors that prevent ground bounce or transient voltage fluctuations on active chassis backplanes.

Q: How does the transceiver perform under dense thermal loads, ESD events, and what is its calculated MTBF?

The HW-OPT-10G-SFP-10KM operates within a 0°C to +70°C case temperature range (storage: -40°C to +85°C). Encased in an all-metal, high-thermal-conductivity zinc alloy housing, it provides superior EMI shielding and heat dissipation, ideal for high-density 48-port 1RU switch topologies with tight thermal envelopes. The electrical pins satisfy IEC 61000-4-2 ESD standards (4kV contact, 8kV air discharge), and the optical cavity is protected by high-durability dust plugs. Operating under continuous full line-rate traffic at an ambient 45°C, its Mean Time Between Failures (MTBF) exceeds 3,000,000 hours, keeping the Annualized Failure Rate (AFR) well under 0.2% for carrier-grade and high-uptime mission-critical backbones.

Question 1

What are the core electro-optical specifications and optical link budget of HW-OPT-10G-SFP-10KM?

Accepted Answer

The Huawei HW-OPT-10G-SFP-10KM (BOM: 02318169 / SFP-10G-LR) complies fully with IEEE 802.3ae 10GBASE-LR and SFF-8431/SFF-8472 MSA standards. Utilizing an uncooled 1310nm DFB laser and high-sensitivity PIN receiver, it delivers a line rate of 10.3125 Gbps over duplex LC single-mode fiber (G.652 SMF). Operating on a 3.3V power rail, typical power consumption remains strictly under 1.0W (approx. 0.85W). The optical launch power spans from -8.2 dBm to +0.5 dBm with an extinction ratio > 3.5 dB, while receiver sensitivity reaches down to -14.4 dBm with an overload threshold of +0.5 dBm, offering a minimum dynamic optical link budget of 6.2 dB for robust 10 km reach (BER < 10^-12). Integrated DDM/DOM allows live telemetry of Tx/Rx optical power, bias current, voltage, and internal thermal metrics.
