## Summary description

The BlueOptics SFP-4340-BO is a fiber optic SFP transceiver module designed for high-speed data transmission. It features an LC connector and is made of durable aluminum, weighing only 20g. Ideal for network applications requiring reliable connectivity.

## Long description

The BlueOptics SFP-4340-BO is a fiber optic SFP transceiver module designed for single-mode optical links. It supports 1000BASE-BX-D operation with separate transmit and receive wavelengths, uses an LC simplex connector and is housed in an aluminium enclosure weighing approximately 20 g. The module is intended for use in network equipment that accepts SFP form-factor transceivers and is suitable for point-to-point links over long distances when used with appropriate single-mode fiber.
Advantages
The BlueOptics SFP-4340-BO follows MSA-compliant SFP specifications and provides compatibility with systems that support 1000BASE-BX-D SFP transceivers. Its aluminium casing offers durable protection and a compact lightweight design simplifies handling and installation. The LC simplex connector and single-mode optical design allow simultaneous transmit and receive operation on a single fibre using different wavelengths, enabling long-reach Ethernet or fibre channel applications up to the module’s supported distance when paired with correct cabling and hardware.
Suitable for
Upgrading or replacing SFP ports in switches and routers that support 1000BASE-BX-D
Single-mode point-to-point fiber links between network devices
Storage and SAN connections requiring 1 Gbps optical transceivers
Long-reach links where LC simplex single-mode connections are used
Key specifications
Form factor: SFP (Small Form-factor Pluggable)
Optical connector: LC simplex
Optical type: single-mode fiber operation (separate TX/RX wavelengths)
Supported protocol: 1000BASE-BX-D (1.25 Gbps class links)
Housing material and colour: aluminium / aluminium finish
Weight: approx. 0.02 kg
How to use
Insert the BlueOptics SFP-4340-BO into an available SFP slot on the network device while the device is powered according to the vendor’s hot-swap guidance. Connect an appropriate single-mode LC simplex patch cable between this transceiver and the remote transceiver or patch panel; ensure the transmit and receive ends match the required wavelengths for BX-D operation. After insertion, verify that the host device recognizes the module and that link/activity LEDs indicate an established connection. Follow the host device documentation to enable or configure the port as needed.
Usage recommendations
Use high-quality single-mode LC patch cords and maintain clean connector endfaces to ensure optimal signal levels. Confirm that the host hardware supports 1000BASE-BX-D SFP modules and, if required, enable Digital Diagnostic Monitoring (DDM/DOM) in the host to monitor voltage, laser bias, output and received power, and temperature. Avoid mechanical strain on the fibre and store unused modules in protective packaging to prevent contamination or damage.
