Description

High‑density 100G QSFP28 extended‑SR (XSR4) transceiver for parallel multimode fiber. Delivers four 25G lanes over MPO‑12 with extended reach versus SR4: up to 150 m on OM3 and 300 m on OM4. Ideal for short‑to‑mid fabric links in spine/leaf and aggregation where parallel MMF cabling is available.

Features

- Extended SR reach: up to 300 m on OM4
- Parallel 4x25G lanes for low-latency 100G
- MPO-12 interface for high-density cabling
- Hot-swappable with DOM for easy monitoring
- Standards-compliant interoperability on SR4-class links

FAQs

Q: Does this module support 4x25G breakout?
A: Yes—on hosts that enable breakout, it can fan out to 4x25G SR lanes using an MPO‑to‑4xLC harness and compatible 25G SR endpoints.

Q: Which cable and connector does it require?
A: Use OM3/OM4 multimode fiber with an MPO‑12 (MTP) connector. Observe polarity and clean connectors before mating.

Q: Is it compatible with standard SR4 optics from other vendors?
A: Yes, it interoperates with compliant 100G SR4/XSR4 modules over parallel MMF when link budgets and distances match.

Q: Is FEC required?
A: Not typically for the stated reaches; enabling host FEC can improve margin on challenging links.
