Every WhaleyComm unit is professionally tested, reset to factory defaults, and certified by our in-house engineers — the same standard trusted by 5,000+ organisations across 25 years. Not a refurb marketplace. A certified lifecycle partner.
Cisco original optics, professionally tested, backed by 25+ years of enterprise trust.
This refurbished Cisco XFP-10G-MM-SR is a genuine Cisco 10GBASE-SR XFP transceiver module designed for multimode fiber (MMF) environments. Professionally tested and reset to factory defaults, this unit delivers the same performance as new at a fraction of the cost. As a Cisco original module, it supports the Cisco quality identification (ID) feature, ensuring full recognition and compatibility when installed in a Cisco switch or router.The XFP-10G-MM-SR operates at an 850nm wavelength and is dedicated to 10 Gigabit Ethernet applications over multimode fiber. It supports link lengths of up to 26m on standard FDDI-grade MMF, up to 300m on OM3 fiber (2000 MHz/km), and up to 400m on OM4 fiber (4700 MHz/km). The module connects via a dual LC connector, is fully hot-swappable, and supports optical interoperability with Cisco 10GBASE XENPAK, X2, and SFP+ modules on the same link.
WhaleyComm has supplied enterprise networking hardware for 25+ years to 5,000+ customers across industries. Sourcing refurbished Cisco original optics through WhaleyComm means you get manufacturer-grade hardware, ISO 9001-certified testing, and a Lifetime Warranty — all at a price that protects your budget without compromising your network.

Ideal Use Cases
Data Center Top-of-Rack Connectivity
Deploy the XFP-10G-MM-SR for high-density 10GbE interconnects between top-of-rack switches and aggregation layers over OM3 or OM4 multimode fiber runs of up to 300m or 400m respectively.
Enterprise Campus Distribution Links
Ideal for connecting distribution-layer switches in enterprise campus wiring closets where multimode fiber is already installed and short-to-medium reach 10G connectivity is required.
Intra-Building Backbone Upgrades
Use this module to upgrade legacy 1G intra-building fiber backbones to 10G without recabling, leveraging existing multimode fiber infrastructure for a cost-effective path to higher bandwidth.
Cisco Switch and Router XFP Port Population
Purpose-built for Cisco platforms with XFP slots, this genuine Cisco module ensures full Cisco quality ID recognition and eliminates compatibility concerns common with third-party optics.
Lab and Staging Environments
A cost-effective way to fully replicate production 10GbE fiber connectivity in test, lab, or pre-production environments using genuine Cisco original hardware at refurbished pricing.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
Yes. According to the official Cisco datasheet, this module supports link lengths of up to 300m on OM3 (2000 MHz/km) multimode fiber and up to 400m on OM4 (4700 MHz/km) multimode fiber. It also supports 26m on standard FDDI-grade MMF.
Yes. As a Cisco original module, the XFP-10G-MM-SR supports the Cisco quality identification (ID) feature, which allows a Cisco switch or router to identify it as a Cisco certified and tested XFP. This avoids the unsupported-transceiver warnings that can occur with third-party optics.
No. The official Cisco datasheet specifies that only patch cords with PC or UPC connectors are supported. Patch cords with APC (Angle Polished Connector) polished face types are not supported by the dual LC connectors on this XFP module.
Yes. Every WhaleyComm unit ships with a Lifetime Warranty. If it fails under normal operating conditions at any point, we replace it at no cost — no time limits, no questions asked.
Every unit goes through our ISO 9001-certified testing process: full power-on diagnostics, port-by-port functionality testing, firmware verification, factory reset, and final inspection. A Certificate of Testing ships with every unit.
