Used Cisco Fiber Transceivers

A Cisco fiber optic transceiver is a device that integrates a laser, an optical driver, an electronic driver, and an optical interface. It is used to convert electrical signals into optical signals and transmit them between optical fibers, as well as to reduce the signals from light to electrical signals. These transceivers provide high-speed, stable data transfer between network devices over fiber-optic media, and are essential or indispensable components for building modern, high-performance network infrastructures.

Cisco fiber transceivers are widely used in enterprise networks, data centers, wide area networks (WANs), and computing. In these applications, fiber transceivers are used to connect switches, routers, servers, storage devices, and more to create high-speed, highly reliable network infrastructures.

In short, Cisco fiber optic transceivers provide users with powerful fiber optic communications solutions that support network deployments of all sizes and types through their high performance, reliability, and flexibility.

We offer a 3-month warranty on used Cisco fiber transceivers purchased from linknewnet. Upon receipt of your order, we will thoroughly test and maintain the equipment prior to shipment to ensure that you receive a virtually new product and experience the best technical support available!

Frequently Asked Questions

What used transceivers and optics does LinkNewNet sell?

We carry used and surplus SFP, SFP+, QSFP+, QSFP28 and compatible optical transceivers for Cisco and other major platforms (10G and 40G Ethernet, plus fiber/copper variants). Give our sales team the exact model or port requirement and we will match the right optic.

Are used transceivers tested before shipping?

Yes. Every transceiver is tested by our engineers before shipment - optical power, link negotiation and DOM (Digital Optical Monitoring) are verified where supported - and ships with a free 3-month warranty, extendable on request.

Will a used transceiver work in my switch, router or module?

Compatibility depends on the port type, speed and media - for example a 10G SFP+ port accepts 10G SFP+ optics and, on most platforms, 1G SFP optics. Give our sales team your platform and port type; we will confirm compatibility before you buy.

What after-sales support comes with used transceivers?

A free 3-month warranty is included with every unit (extendable on request), plus after-sales support via WhatsApp (+86 18954776148) or email (cs@linknewnet.com).
