Applications
Network architects choose the 1G SFP GLC-SX-MMD 550m 850nm Duplex LC/UPC Industrial Module, Cisco for enterprise access, campus, telecom edge and industrial network environments: it runs 1.25Gbps over MMF and reaches 550m over OM2 MMF. With its Duplex LC optical interface, the module works directly with the MMF infrastructure already installed in most facilities. Compatibility with Cisco systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of GLC-SX-MMD.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the Cisco part GLC-SX-MMD and works in Cisco systems out of the box. Standards compliance covers IEEE 802.3z, SFF-8472, FC-PI, SFP MSA (INF-8074i) Compliant.
Ordering Information
To order, quote SFP1G-SX-85-I together with your quantity. Stock items ship quickly; for OEM orders we support custom labels, retail packing and vendor-specific coding, all handled in our own factory.
Packing Details
Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.
OEM and Custom Orders
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.
Logistics
Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.
Quality and Testing
Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.
