GLC-2BX-D-I Cisco SFP Module

The industry-standard Cisco Small Form-Factor Pluggable (SFP) Gigabit Interface Converter links your switches and routers to the network. The hot-swappable input/output device plugs into a Gigabit Ethernet port or slot. Optical and copper models can be used on a wide variety of Cisco products and intermixed in combinations of 1000BASE-T, 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-EX, 1000BASE-ZX, or 1000BASE-BX10-D/U on a port-by-port basis.

1000BASE-T SFP for copper networks The 1000BASE-T SFP operates on standard Category 5 unshielded twisted-pair copper cabling of link lengths up to 100 m (328 ft). Cisco 1000BASE-T SFP modules support 10/100/1000 auto negotiation and Auto MDI/MDIX.

Cisco SFP Module Features and benefits

• Hot swappable to maximize uptime and simplify serviceability
• Flexibility of media and interface choice on a port-by-port basis, so you can “pay as you populate”
• Robust design for enhanced reliability
• Supports Digital Optical Monitoring (DOM) capability

The Cisco 1-Gbps SFPs are supported across a variety of Cisco networking equipment^*. For more details, refer to the document SFP Compatibility Matrix

Almost all Cisco platforms which have SFP ports can use this SFP Module

What is the difference between LH and LX modules?

The 1000BASE-LX, 1000BASE-LH and 1000BASE-LX/LH all refer to Gigabit Ethernet transmission. Among them, the 1000BASE-LX is a standard specified in IEEE 802.3 Clause 38 which uses a long wavelength laser, while the 1000BASE-LH and 1000BASE-LX/LH are just terms widely used by many vendors. Long Haul (LH) denotes longer distances while Long Wavelength (LX) denotes less energy which is obviously shorter distance. The 1000BASE-LX SFP modules compatible with the IEEE 802.3z 1000BASE-LX standard can achieve a distance up to 10km over single mode fiber. Unlike 1000BASE-LX SFP modules, 1000BASE-LH SFP modules operate at a distance up to 70km over single mode fiber.

Can 1000BASE-LX be compatible with 100BASE-LX?

1000BASE-LX and 100BASE-LX are very different standards. 1000BASE-LX SFP (GLC-LH-SMD) and 100BASE-LX SFP (GLC-FE-100LX) are two module types, one for GE and one for FE slots. The GLC-LH-SMD does not operate at 100Mbps. You will need to use a 100Mb module to connect to another device at 100Mb. Check optical transceiver compatibility with your equipment by reviewing the Cisco Fast Ethernet SFP module compatibility document and choose the one it says is compatible.
