Description

Dense Wavelength Division Multiplexing (DWDM) SFP transceiver for 2 Gbps links over single-mode fiber at 1547.72 nm. Built for ITU-T G.694.1 C-band (100 GHz) DWDM systems with LC duplex connectivity. Requires a corresponding DWDM MUX/DEMUX; achievable reach depends on link budget and any optical amplification.

Features

- Fixed DWDM wavelength: 1547.72 nm (C-band, 100 GHz grid)
- 2 Gbps line rate for high-capacity metro/long-haul links
- LC duplex interface over single-mode fiber
- DOM/DDM for real-time optical monitoring
- Hot-swappable SFP for rapid service turn-up and replacement

Warranty

All products sold by XS Network Tech include a 12-month warranty on both new and used items. Our in-house technical team thoroughly tests used hardware prior to sale to ensure enterprise-grade reliability.

All technical data should be verified on the manufacturer data sheets.

FAQs

Q: Do I need a DWDM MUX/DEMUX to use this optic?
A: Yes. This module is designed for ITU-T DWDM systems and requires a matching DWDM MUX/DEMUX channel and single-mode fiber.

Q: What fiber type and connector does it use?
A: Single-mode fiber (OS2) with an LC duplex connector.

Q: How far can this module reach?
A: Reach is link-budget dependent. With appropriate dispersion management and amplification (e.g., EDFA), metro to long-haul distances are achievable.

Q: Is it hot-swappable and does it support DOM?
A: Yes, it is hot-swappable and supports digital diagnostics (DOM/DDM) for monitoring.

Q: Which ports is this compatible with?
A: SFP ports that support 2 Gbps DWDM optics. Verify platform and rate compatibility before deployment.
