Features

WFD5H80A-ECL61

The CWDM SFP 2.5G 80km LC SMF transceiver is a high-performance optical module designed for long-haul transmission over standard single-mode fiber. Operating at 2.5Gbps with 80km reach, it is ideal for SONET OC-48, SDH STM-16, and Gigabit Ethernet applications. Leveraging CWDM technology with 18 wavelengths from 1270nm to 1610nm, it maximizes fiber capacity by enabling multiple channels over a single fiber. Built with a CWDM DFB laser and APD receiver, it delivers reliable signal integrity across the full 80km span. Fully SFP MSA compliant with LC interface, hot-swappable, and featuring real-time DDM for proactive maintenance, this module offers carrier-grade reliability for diverse deployment environments.

1. Supports up to 2.5Gb/s data rates

The CWDM SFP 2.5G 80km LC SMF transceiver delivers 2.5Gbps throughput that easily handles heavy traffic loads like video streaming and large data backups. This speed keeps your network running smoothly during peak hours without delays or bottlenecks. It gives you the capacity you need for today's applications and room to grow for tomorrow's demands.

2. 8-Wavelength CWDM DFB laser from 1470nm to 1610nm with step 20nm and APD photodiode

The CWDM SFP 2.5G 80km LC SMF transceiver equipped with an 8-wavelength CWDM DFB laser covering 1470nm to 1610nm in 20nm steps, this module gives you plenty of wavelength choices for your network. This flexibility lets you run multiple channels over the same fiber, getting more value from your existing cabling. The built-in APD photodiode provides excellent sensitivity, keeping your signal clean and strong over long distances. Together, these components deliver a cost-effective solution that makes the most of your fiber infrastructure.

3. Compatible with RoHS-6

The CWDM SFP 2.5G 80km LC SMF transceiver uses environmentally friendly materials that fully comply with RoHS-6 requirements. This means you can meet global environmental regulations without extra effort or paperwork. By choosing this module, you are supporting sustainable practices and reducing your environmental impact. It is a responsible choice that delivers reliable performance while caring for the planet.
