## Summary description

The BlueOptics J9143B is an SFP transceiver module designed for fiber optic connections. It supports a maximum data transfer rate of 1250 Mbit/s, ensuring efficient data transmission. This module is ideal for networking applications requiring reliable and fast connectivity.

## Long description

The BlueOptics J9143B Fiber optic SFP transceiver provides a compact solution for single-port fiber connections. Designed for network environments that require a small form-factor pluggable module, this SFP transceiver supports a maximum data transfer rate of 1250 Mbit/s and is compatible with standard SFP slots. The module enables optical link establishment for switches, routers, media converters and other network equipment that accept SFP transceivers.
Advantages
The module combines a compact SFP form factor with fiber optic transmission to deliver reliable point-to-point connectivity over optical cable. With a 1250 Mbit/s data rate it supports typical Fast Ethernet/SONET applications where optical links are required. The transceiver is hot-pluggable, which simplifies installation and maintenance without powering down host equipment. Its design focuses on interoperability with common networking devices that use SFP interfaces.
Suitable for
Establishing fiber links between switches and routers
Media converters and fiber extension of copper ports
Campus and enterprise network segments requiring small-form-factor optics
Replacement or expansion of existing SFP fiber ports
Key specifications
Interface type: SFP (small form-factor pluggable)
Maximum data transfer rate: 1250 Mbit/s
Optical fiber medium: single-mode or multimode depending on cable and system compatibility
Application: optical point-to-point links for networking equipment
Mounting: hot-pluggable module for SFP slots
How to use
Insert the transceiver into an available SFP slot on the host device until it clicks into place, observing electrostatic discharge precautions. Connect the appropriate fiber optic cable to the transceiver connector and secure any required dust caps when not in use. Configure the host device port for the intended link speed and media type as required by the network equipment. Monitor link and interface status through the host device management tools to confirm proper operation.
Usage recommendations
Use fiber cable and connectors that match the transceiver and host system requirements. Ensure proper transmitter and receiver pairing (wavelength and fiber type) and check device compatibility lists where available. Maintain clean connectors and follow standard optical handling procedures to preserve signal quality.
