The 1G SFP GLC-BX-20U 20km 1310nm-TX/1550nm-RX Simplex LC/UPC Module, Cisco is used in enterprise access, campus, telecom edge and industrial network environments, where it provides a 1.25Gbps link over SMF up to 20km. The Simplex LC/UPC interface and 1310nm-TX/1550nm-RX optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. It is interoperable with Cisco platforms and replaces the Cisco part GLC-BX-20U directly.

Compliance: Fast Ethernet, Gigabit Fibre Channel, MSA Compliant. For projects standardized on Cisco hardware, this product replaces the GLC-BX-20U directly, with identical fit and function. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.

Order this product as SFP-1G35-BX20. 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.

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.

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.

Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.

As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.
