Description

Compact, hot-swappable DWDM SFP+ transceiver for 10G long‑reach links up to 40 km over single‑mode fiber. Fixed 1538.98 nm C‑band wavelength on the 100 GHz DWDM grid with DOM for real‑time diagnostics. Ideal for metro, aggregation, and DWDM transport where precise channel planning is required.

Features

- Fixed DWDM C‑band wavelength for dense channel deployment
- Long‑reach 40 km over standard single‑mode fiber
- 10GBASE‑ER performance with low latency and transparent transport
- DOM/DDM for proactive monitoring and troubleshooting
- Hot‑swappable SFP+ for rapid maintenance and upgrades
- Standards‑based MSA compliance for broad interoperability

FAQs

Q: Will this work in any 10G SFP+ port?
A: It is designed for 10G SFP+ ports that support DWDM/ER optics; consult your platform’s optics compatibility list.

Q: Do I need the same wavelength at both ends?
A: Yes, both ends must use transceivers with the same DWDM channel/wavelength.

Q: What fiber type and connector are required?
A: Single‑mode OS2 fiber with duplex LC connectors.

Q: Does it support DOM?
A: Yes, it supports digital optical monitoring for TX/RX power, temperature, and voltage.

Q: Can it always reach 40 km?
A: Up to 40 km with an appropriate loss budget; actual reach depends on fiber quality, splices, and patching.
