Description

Compact DWDM SFP transceiver tuned to 1559.79 nm on the ITU-T G.694.1 100 GHz C-band grid for high-density, long-haul single-mode links. Supports up to 2 Gbps across DWDM mux/demux systems using an LC duplex interface; ideal for metro/backbone extensions where channelized wavelength planning is required.

Features

- Tuned 1559.79 nm wavelength for precise DWDM channel planning
- Compact SFP footprint for high port density
- Single-mode LC interface for low-loss connections
- Operates on ITU-T G.694.1 100 GHz DWDM grid
- Optimized for long-haul and metro aggregation links

FAQs

Q: Is a DWDM MUX/DEMUX required?
A: Yes, DWDM optics are designed to operate with a DWDM mux/demux to combine multiple wavelengths onto a single fiber pair.

Q: What fiber type is supported?
A: Single-mode fiber (SMF) with LC duplex connectors.

Q: Which channel spacing does it use?
A: 100 GHz spacing on the ITU-T G.694.1 DWDM grid.

Q: How far can this optic reach?
A: Reach is long-haul and depends on the overall optical budget, including fiber attenuation, mux/demux insertion loss, and any amplification.
