Q: What is the hardware platform compatibility of this module, and does it support 4x25G breakout mode and multi-rate port mixing?

The module natively supports Huawei CloudEngine series switches (CE6800, CE8800, CE9800, and CE12800/16800 line cards) and NetEngine routers (NE40E, NE8000 QSFP28 PICs) with pre-coded EEPROM microcode, bypassing Huawei non-certified optics alarms. It fully supports 4x25G breakout operation when configured via CLI ('port split'), interconnecting seamlessly with four 25GBASE-SR SFP28 transceivers over MPO-to-4xLC fan-out assemblies with independent per-channel CDR locking. The module operates without thermal or electrical interference when coexisting alongside 40G QSFP+ or 100G CWDM4 transceivers in adjacent cage slots, supported by isolated I2C bus arbitration and zero data plane packet jitter during hot-plugging.

Q: What reliability, EMI shielding, and thermal designs protect this transceiver in dense data center environments?

Engineered for demanding data center environments, the module operates across a 0°C to +70°C case temperature range (-40°C to +85°C storage). It features an all-metal zinc alloy die-cast housing combined with a 360-degree EMI spring gasket, delivering > 40 dB shielding effectiveness at 25 GHz to eliminate inter-cage crosstalk and provide > 2kV ESD human-body model protection. The power filtering stage incorporates over-current protection (OCP), TVS voltage clamp arrays, and a soft-start circuit restricting inrush current to < 30mA, preventing transient voltage spikes during hot insertion. Its calculated MTBF exceeds 1,500,000 hours per Telcordia SR-332, ensuring resilience in both port-to-power and power-to-port airflow racks.

Question 1

What are the core optical parameters and electrical specifications of the Huawei 100G QSFP28 850nm MM transceiver (HW-OPT-100G-QSFP28-MM)?

Accepted Answer

Compliant with IEEE 802.3bm 100GBASE-SR4 and SFF-8665, this transceiver converts 4-lane 25.78125 Gbps NRZ electrical data via on-board CDRs to a 4-channel 850nm VCSEL emitter array and PIN photodetector array. Featuring an MPO/MTP-12 connector (Type-B polarity, 8 active fibers), it achieves link lengths up to 70m on OM3 and 100m on OM4 MMF. Operating from a single +3.3V power rail, typical power dissipation is optimized to < 2.5W. Transmitter optical power per lane ranges from -8.4 dBm to +2.4 dBm, with receiver sensitivity better than -10.3 dBm (OMA, using Clause 91 RS-FEC 528,514). It includes SFF-8636 compliant Digital Optical Monitoring (DOM) for real-time telemetry of internal temperature, supply voltage, Tx bias current, Tx optical power, and Rx optical power.
