In enterprise access, campus, telecom edge and industrial network environments, the 1G SFP 2km 1310nm Duplex LC/UPC Industrial Module, Cisco delivers 1.25Gbps transmission over SMF/MMF with a reach of 2km. With its Duplex LC optical interface, the module works directly with the SMF/MMF infrastructure already installed in most facilities. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment.
Standards compliance covers SFF-8472MSAIEEE 802.3. The unit works in any equipment with a standard SFP interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.
Our part number for this module is SFP1G-SX-31-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.
Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.
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.
Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.
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.
