Description

High-performance 10G DWDM SFP+ transceiver tuned to 1557.36 nm for ITU-T DWDM systems. Delivers up to 40 km reach over OS2 single‑mode fiber using LC duplex connectors and supports digital diagnostics (DOM) for real‑time monitoring of link health. Ideal for metro backhaul and high‑density DWDM mux/demux deployments where wavelength-specific planning is required.

Features

- Channel-accurate tuning to C25 (1557.36 nm)
- Up to 40 km 10G reach for metro and access aggregation
- Real-time DOM for proactive maintenance
- MSA-compliant SFP+ form factor for broad device support
- LC duplex interface over OS2 SMF

FAQs

Q: Which ITU channel does 1557.36 nm map to?
A: ITU-T 100 GHz DWDM channel C25.

Q: Is amplification required for 40 km?
A: Not typically, provided the link budget is within spec. High-loss paths may require amplification or dispersion management.

Q: Does it support digital diagnostics?
A: Yes. DOM/DDM is supported for monitoring optical parameters.

Q: What connector type is used?
A: LC duplex on OS2 single‑mode fiber.

Q: Is it hot-swappable?
A: Yes, it can be inserted or removed without service interruption to the host device.
