• Connector: Duplex LC
• Reach: up to 40km
• Fiber media: SMF
• Operating temperature: 0 to 70°C (32 to 158°F)

In enterprise access, campus, telecom edge and industrial network environments, the 1G SFP GLC-EX-SM1550-40 40km 1550nm Duplex LC/UPC Module, Cisco delivers 1.25Gbps transmission over SMF with a reach of 40km. The Duplex LC interface and 1550nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. 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-EX-SM1550-40.

This product is designed and tested to comply with SFF-8472 MSA Compliant, IEEE 802.3ah-2004. It is interoperable with Cisco equipment and serves as a direct equivalent to the Cisco part number GLC-EX-SM1550-40.

Our part number for this module is SFP1G-EX-55. 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.

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.

Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.

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.

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.
