## Summary description

CBO iSFP-GIG-LH40 is an SFP fiber optic transceiver compatible with Alcatel-Lucent equipment, offering 1.25 Gbps data rate and a 40 km link reach. Designed for single-mode fiber links, it provides a hot-pluggable uplink/downlink interface for switches and routers. Use it to extend networks over long distances, enable WAN connections, or replace faulty SFP modules for reliable optical connectivity.

## Long description

CBO iSFP-GIG-LH40 is an SFP fiber optic transceiver module designed for single-mode fiber applications. It supports a data rate of 1.25 Gbps and a link reach up to 40 km, providing a hot-pluggable uplink or downlink interface for compatible switches and routers. The module is compatible with equipment from Alcatel-Lucent and is intended for point-to-point long-distance optical connections where stable, low-latency transmission is required.
Advantages
The transceiver delivers a stable 1.25 Gbps transfer rate over single-mode fiber and supports distances up to 40 km, enabling long-reach connectivity without additional media converters. Its hot-pluggable SFP form factor allows easy replacement or upgrade without powering down network devices. The module is built to industry specifications for interoperability with network switches and routers, ensuring predictable optical performance for uplinks, downlinks, and WAN links.
Suitable for
 Extending Ethernet links between buildings or across campus networks over single-mode fiber
 WAN uplinks between switches, routers and carrier equipment
 Replacing faulty or incompatible SFP modules in existing network hardware
 Dedicated point-to-point fiber links requiring 1.25 Gbps throughput
Key specifications
 Form factor: SFP (Hot-pluggable)
 Data rate: 1.25 Gbps
 Fiber type: Single-mode fiber
 Maximum link distance: Up to 40 km (dependent on fiber and link budget)
 Wavelength: Typical single-mode transmission wavelength (device-specific)
 Interface: Optical LC connector
 Operating temperature range: Industry-standard commercial range (refer to vendor documentation for exact values)
How to use
Insert the SFP transceiver into a compatible SFP slot on a switch or router until it seats firmly and the latch engages. Connect a single-mode LC fiber patch cable to the module, observing correct transmit/receive orientation. Configure the network device port as required (speed/duplex and optical settings) and verify link status through device management interfaces. Replace the module while the device is powered on if supported by the hardware; follow standard electrostatic discharge precautions during handling.
Usage recommendations
For reliable performance, use low-loss single-mode fiber and quality LC patch cables compatible with long-reach links. Verify optical power budget and fiber attenuation for distances approaching 40 km, and confirm compatibility with your switch or router firmware. Handle the transceiver by its housing, keep optical interfaces clean, and use dust caps when not connected.
