Description

Gigabit DWDM SFP tuned to 1534.25 nm (ITU Channel 43) for high-density C-band transport over single-mode fiber. Supports up to 80 km with appropriate DWDM link budget, LC duplex interface, hot-swap operation, and DOM for real-time diagnostics—ideal for metro, backbone, and wavelength services with 100 GHz mux/demux systems.

Features

- ITU-tuned 1534.25 nm (Ch 43) for dense wavelength multiplexing
- Long-reach up to 80 km over SMF
- Hot-swappable SFP form factor for rapid service turn-up
- LC duplex interface simplifies patching and integration
- DOM support enables precise optical performance monitoring
- Cooled DFB laser for stable wavelength accuracy on 100 GHz grids

FAQs

Q: Do I need a DWDM mux/demux to use this module?
A: Yes. It is designed for ITU 100 GHz DWDM systems and should be paired with a matching 100 GHz mux/demux.

Q: Must both ends use the same channel?
A: Yes. Use the identical ITU channel/wavelength at both ends for a working DWDM link.

Q: Will it work in any SFP port?
A: Use a 1G SFP port that supports optical transceivers and DOM; it does not operate at 10G.

Q: What fiber and connector are required?
A: Single-mode fiber (G.652 or equivalent) with LC duplex connectors.

Q: How far can it reach?
A: Up to 80 km under typical conditions. Actual distance depends on total link loss, splices, connectors, and any amplifiers/attenuators.

Q: Does it support digital diagnostics?
A: Yes, it supports SFF-8472 DOM/DDM for monitoring TX/RX power, temperature, and more.
