Description

DWDM SFP transceiver for OC-48/STM-16 (≈2.5 Gbps) single-mode links. Tuned to 1545.3 nm on the ITU-T C-band 100 GHz grid, it provides long-reach performance up to 80 km with LC duplex connectivity and digital diagnostics for real-time monitoring. Ideal for metro and long-haul DWDM transport over SMF.

Features

- Tuned DWDM wavelength at 1545.3 nm for dense channel plans
- Long-reach performance up to 80 km over SMF
- Standards-based OC-48/STM-16 operation for SONET/SDH networks
- LC duplex interface for easy integration with DWDM mux/demux
- DOM/DDM monitoring for proactive link maintenance

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.

FAQs

Q: Is this module on the ITU DWDM grid?
A: Yes. It is tuned to 1545.3 nm on the ITU-T C-band 100 GHz DWDM grid.

Q: What is the supported distance?
A: Up to 80 km over SMF under typical DWDM link budgets; actual reach depends on total loss, amplification, and dispersion.

Q: Which connector type does it use?
A: LC duplex.

Q: Does it support digital diagnostics (DOM/DDM)?
A: Yes, it provides DOM/DDM for real-time monitoring of temperature, power, and voltage.

Q: Can this be used for Ethernet?
A: It is designed for OC-48/STM-16 line rates. Use Ethernet-specific optics for Ethernet services unless your platform supports appropriate mapping.
