Built for enterprise access, campus, telecom edge and industrial network environments, this SFP module carries 1.25Gbps over SMF up to 120km per link. The Simplex LC interface and 1550nm-TX/1490nm-RX 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-BX120-D.

Compliance: Fast Ethernet, Gigabit Fibre Channel, MSA Compliant. For projects standardized on Cisco hardware, this product replaces the GLC-BX120-D 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.

Our part number for this module is SFP-1G54-BX120. 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.

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.

We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.

Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.
