Deployment / Use Cases
This upstream SFP module is typically deployed in pairs with downstream BX modules to create complete bidirectional fiber links. Common applications include connecting access switches to distribution or core switches in enterprise networks, linking remote buildings in campus environments, and extending network segments in service provider access networks.
The 10-kilometer reach makes it suitable for metropolitan area network (MAN) connections, inter-data center links within the same campus, and fiber-to-the-building (FTTB) deployments. Network administrators value its compatibility with existing Cisco infrastructure and straightforward installation process.
Enterprise Campus Networking
Connect distribution layer switches to core switches across multiple buildings while conserving fiber resources. The single-fiber design reduces cabling complexity in conduit-constrained installations.
Service Provider Access
Deploy in point-to-point links for business Ethernet services, connecting customer premises equipment to aggregation points. The 10 km reach accommodates typical metro access distances.
Physical Profile
The module measures 0.33 inches in height, 0.53 inches in width, and 2.22 inches in depth (8.50 mm × 13.40 mm × 56.50 mm), conforming to the SFP MSA specification. This compact form factor allows high-density deployment in switch chassis with multiple SFP slots. The standard SFP latch mechanism ensures secure seating in compatible slots while allowing tool-less insertion and removal for maintenance.

FAQ
What is the difference between upstream and downstream BX SFP modules?
BX (bidirectional) SFP modules come in upstream and downstream pairs that operate on different wavelengths. The upstream module (GLC-BX-U=) transmits at 1490 nm and receives at 1310 nm, while the downstream module transmits at 1310 nm and receives at 1490 nm. They must be used in matched pairs to create a complete bidirectional link over a single fiber strand.
Which Cisco switches are compatible with the GLC-BX-U= SFP module?
This module is compatible with Catalyst 2960 series (WS-C2960-24TC-L, WS-C2960-48TC-L, WS-C2960G-24TC-L), Catalyst 3560 series (WS-C3560-24PS, WS-C3560-48PS, WS-C3560G-24TS, WS-C3560G-48TS, WS-C3560G-48PS, WS-C3560G-24PS, WS-C3560-48TS, WS-C3560-24TS), Catalyst 3750 series (WS-C3750-24TS, WS-C3750-48TS, WS-C3750-24PS, WS-C3750-48PS, WS-C3750G-12S, WS-C3750G-24TS, WS-C3750G-48TS, WS-C3750G-24PS, WS-C3750G-48PS), Catalyst 4500 series (WS-X4013+TS, WS-X4013+10GE, WS-4448-GB-SFP, WS-X4506-GB-T, WS-X4516-10GE), Catalyst 4900 series (WS-C4948), Catalyst 6500 series (WS-SUP720, WS-SUP32-8GE-3B, WS-SUP32-10GE-3B, WS-X6724-SFP, WS-X6748-SFP), and Cisco ME 3400 series (ME-3400-24TS-A, ME-3400-24TS-D).
What type of fiber cable should I use with this SFP module?
The GLC-BX-U= requires single-mode fiber (SMF) with LC connectors. You'll need a single strand of single-mode fiber (not a duplex pair) with LC connectors on both ends. The module supports distances up to 10 kilometers over standard 9/125μm single-mode fiber. Ensure the fiber patch cables meet industry standards for low insertion loss to maintain optimal link performance.
Does this SFP module support digital diagnostics monitoring (DOM)?
Yes, the GLC-BX-U= is DOM-capable, meaning it can report real-time operating parameters such as temperature, voltage, laser bias current, transmitted optical power, and received optical power. This information is accessible through the switch's management interface (CLI or web GUI) on compatible platforms, allowing network administrators to monitor link health and troubleshoot performance issues proactively.
