Description

Multi‑rate CWDM SFP supporting OC‑48/STM‑16 and Gigabit Ethernet at the 1610 nm ITU CWDM wavelength. Designed for long‑haul single‑mode links with duplex LC interface and full digital diagnostics (DOM). Suitable for converged transport networks carrying both SONET/SDH and Ethernet services.

Features

- Dual-rate support for OC-48/STM-16 and 1G Ethernet
- CWDM 1610 nm wavelength for dense service multiplexing
- Long-haul capability on standard SMF
- Integrated digital diagnostics for simplified operations
- Hot-swappable design for minimal downtime
