SFP Transceiver CBO TN-SFP-LXB42 1000Base-LX 1310 nm Single-Mode Fiber

The BlueOptics SFP Transceiver CBO TN-SFP-LXB42 1000Base-LX is a small form-factor pluggable module designed for gigabit Ethernet over single-mode fiber. Operating at a wavelength of 1310 nm, this SFP transceiver supports 1000Base-LX links and is intended for use in network equipment with standard SFP slots. The module provides hot-pluggable installation, interoperable connectivity with switches, routers and media converters, and is optimized for long-reach backbone and campus links over single-mode fiber.

Advantages

This SFP transceiver delivers reliable gigabit performance over single-mode fiber with a 1310 nm wavelength suited to long-distance LX transmission. Hot-pluggable design allows module replacement or installation without powering down equipment, minimizing maintenance downtime. The transceiver follows common SFP form-factor conventions for broad compatibility with network switches, routers and fiber converters. Its focus on single-mode fiber ensures lower attenuation and stable links for backbone and distribution paths.

Suitable for

• Gigabit Ethernet uplinks between switches and routers over single-mode fiber
• Backbone and campus network connections requiring extended reach
• Media converters and fiber interface modules in network cabinets
• Redundant or hot-swappable links in data center or enterprise networks

Key specifications

• Interface type: SFP (small form-factor pluggable)
• Data rate: 1000 Mbps (1000Base-LX)
• Wavelength: 1310 nm
• Fiber type: Single-mode fiber (SMF)
• Form factor: Hot-pluggable SFP module
• Typical reach: LX-class long-reach distances over single-mode fiber (vendor-specific distance varies with fiber type and conditions)
• Connector: LC duplex

How to use

Insert the SFP transceiver into an available SFP slot on a compatible switch, router or media converter until it seats firmly. Connect LC duplex single-mode fiber patch cables, ensuring correct transmit-to-receive alignment between link endpoints. Verify link negotiation on the network device and confirm 1000Base-LX operation and link status through device management interfaces. For hot-swapping, remove or insert the module while following the host device’s guidance to avoid transient link issues.

Recommendations

Use this transceiver with single-mode fiber and LC duplex patch cords rated for 1310 nm operation. Check compatibility lists or SFP support matrices from your network equipment vendor and verify link distance requirements based on fiber type and path loss. Observe electrostatic discharge precautions when handling the module and keep optical ports protected from dust when not connected.
