Description

10GBASE-ER CWDM SFP+ module for 10 GbE links up to 40 km over OS2 single-mode fiber at the 1490 nm CWDM wavelength. Suited for coarse wavelength-division multiplexing with 20 nm spacing, enabling efficient fiber aggregation. Supports hot-swap installation and DOM for live optical diagnostics. MSA-compliant for use in standards-based SFP+ ports.

Features

- CWDM 1490 nm channel for multi-wavelength transport
- 40 km long-reach 10GBASE-ER performance
- DOM-enabled for simplified troubleshooting
- MSA-compliant SFP+ for wide interoperability
- Low-touch deployment with hot-swappable design
