Huawei QSFP28‑100G‑SR4 Optical Transceivers – Product Description,
The Huawei QSFP28‑100G‑SR4 Optical Transceiver is a high‑speed, hot‑pluggable optical module designed to support 100 Gigabit Ethernet over short‑range multi‑mode fiber (MMF) links. It uses the QSFP28 form factor and conforms to the 100GBASE‑SR4 standard, which transmits data at 100 Gbps using four parallel 25 Gbps lanes. This module is ideal for data center connectivity, high‑performance computing, enterprise backbone networks, and switch‑to‑switch links where short distances and high bandwidth are required.
The QSFP28‑100G‑SR4 module delivers high throughput at low power, supports Digital Diagnostic Monitoring (DDM) for real‑time optical performance insights, and is widely deployed in 100 G switching fabrics for server farm interconnects and aggregation layers.

Use DDM to view real‑time metrics like transmit/receive power, temperature, and supply voltage for troubleshooting and predictive maintenance.
Frequently Asked Questions (FAQ)
1. What does SR4 mean?
SR4 stands for Short‑Reach 4‑lane, meaning the optical module uses four parallel optical signals for short‑distance 100 Gbps transmission over multi‑mode fiber.
2. Which fiber type is needed for SR4 optics?
You must use multi‑mode fiber (MMF) — typically OM3 or OM4, depending on distance requirements.
3. How far can QSFP28‑100G‑SR4 transmit?
- Up to 100 m on OM4 fiber
- Approximately 70 m on OM3 fiber
4. What connector type does it use?
It uses an MPO‑12 connector for parallel transmission (4 lanes × 25 Gbps).
5. Is this hot‑pluggable?
Yes — QSFP28 modules are hot‑swappable, enabling installation or removal without powering down equipment.
6. Does the module support diagnostics?
Yes — it supports Digital Diagnostic Monitoring (DDM) to view optical parameters such as temperature, transmit/receive power, and voltage.
7. Are Huawei QSFP28 SR4 transceivers compatible with other brands?
They can be compatible with equipment from other vendors if those devices support the 100GBASE‑SR4 standard and allow third‑party optical modules.
