Applications
The 1G SFP GLC-BX120-U 120km 1490nm-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 120km. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. 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-U.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the Cisco part GLC-BX120-U and works in Cisco systems out of the box. Standards compliance covers Fast Ethernet, Gigabit Fibre Channel, MSA Compliant.
Ordering Information
Our part number for this module is SFP-1G45-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.
How We Ship
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.
Reliability Control
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.
Packaging
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.
Factory Custom Capability
Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.
