In enterprise access, campus, telecom edge and industrial network environments, the 1G SFP GLC-SX-MMD 550m 850nm Duplex LC/UPC Industrial Module, Cisco delivers 1.25Gbps transmission over MMF with a reach of 550m over OM2 MMF. With its Duplex LC optical interface, the module works directly with the MMF infrastructure already installed in most facilities. It is interoperable with Cisco platforms and replaces the Cisco part GLC-SX-MMD directly.

This product is designed and tested to comply with IEEE 802.3z, SFF-8472, FC-PI, SFP MSA (INF-8074i) Compliant. It is interoperable with Cisco equipment and serves as a direct equivalent to the Cisco part number GLC-SX-MMD.

Our part number for this module is SFP1G-SX-85-I. When ordering, just let us know the quantity and whether you need the compatibility coding for a particular switch brand; labeling and packaging can also follow your channel requirements.

Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.

We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.

We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.

Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.
