Description

High‑reach multi‑rate QSFP+ transceiver for 40GbE or 4x10GbE breakout over single‑mode fiber. ER4 optics on 1310nm CWDM lanes deliver up to 40 km reach via LC duplex. Digital diagnostics and hot‑swap design streamline operations; host FEC is recommended to realize maximum distance.

Features

- Extended 40 km reach over single‑mode fiber
- Multi‑rate operation: 40G or 4x10G on supported hosts
- Standards‑based ER4 optics for broad interoperability
- LC duplex interface simplifies long‑reach links
- Digital diagnostics for proactive monitoring
- Hot‑swappable for rapid maintenance

FAQs

Q: Does this module support 4x10G breakout?
A: Yes. When the host platform supports 4x10G operation, the transceiver can operate as four 10G lanes; ensure a compatible breakout configuration at the far end.

Q: What fiber and connector do I need?
A: Use OS2 single‑mode fiber terminated with LC duplex connectors.

Q: Is FEC required?
A: FEC on the host is recommended to achieve the maximum 40 km reach and optimal error performance.

Q: Will it interoperate with other ER4 optics?
A: It follows 40GBASE‑ER4 optical characteristics; interoperability depends on standards compliance and host coding. Verify compatibility on your platform.

Q: Does it provide DOM/DDM?
A: Yes, digital diagnostics are supported for real‑time monitoring.
