WFB53520AA-ECL

1. Single Mode LC Connector SFP Transceiver

The 2.5G SFP BiDi 20km LC single mode transceiver designed with a premium single-mode LC interface, this SFP transceiver ensures a highly stable and precise physical connection that minimizes optical signal loss. Its industry-standard form factor guarantees seamless interoperability with a wide range of mainstream networking switches and routers. You can deploy it instantly into your existing fiber infrastructure without worrying about compatibility mismatches.

2. Up to 20km on 9/125um SMF

The 2.5G SFP BiDi 20km LC single mode transceiver engineered to deliver robust, error-free transmission over distances of up to 20 kilometers on standard 9/125μm single-mode fiber, this transceiver conquers the challenges of long-haul links with ease. Its advanced optical design maintains exceptional signal integrity even at maximum range, effectively eliminating data loss and retransmission delays. Whether spanning campus buildings or connecting remote facilities, you can count on consistent, high-speed connectivity that never lets you down.

3. Compatible with RoHS-6

Manufactured in strict compliance with RoHS-6 environmental directives, The 2.5G SFP BiDi 20km LC single mode transceiver is built with safer materials that protect both people and the planet. Choosing this green-certified module means you are proactively meeting international compliance standards while reducing your company's environmental footprint. Deliver exceptional network performance with a clean conscience, knowing every component meets the world's most rigorous safety and sustainability requirements.

4. Operating Case Temperature

Available in two versatile temperature grades to match your unique deployment environment - Commercial (0 to +70°C) for standard indoor settings and Industrial (-40 to +85°C) for extreme outdoor or factory-floor conditions. This flexible temperature tolerance ensures consistent, drift-free performance whether deployed in climate-controlled data centers or sun-scorched roadside cabinets. Choose the grade that fits your world, and rest assured this transceiver will perform flawlessly mile after mile, season after season.
