In enterprise access, campus, telecom edge and industrial network environments, the 1G SFP GLC-LH-SMD 10km 1310nm Duplex LC/UPC Industrial Module, Cisco delivers 1.25Gbps transmission over SMF with a reach of 10km@SMF. With its Duplex LC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. For networks standardized on Cisco hardware, it is a drop-in equivalent of the GLC-LH-SMD.
On the compatibility side, this unit is the practical equivalent of the Cisco part GLC-LH-SMD and works in Cisco systems out of the box. Standards compliance covers SFF-8472 MSA Compliant, IEEE 802.3ah-2004.
Order this product as SFP1G-LX-31-I. Common models are stocked for fast dispatch. We can supply the module with neutral or customer-branded labels, and compatibility coding for a specific equipment vendor can be added at no extra process step.
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.
Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.
From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.
Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
