Fiber optic transceiver module BlueOptics BN-CKM-S-LX-BO SFP LC connector

The BlueOptics BN-CKM-S-LX-BO is a single-mode fiber optic SFP transceiver module designed for 1000BASE-LX applications. It uses an LC duplex connector and transmits and receives at 1310 nm, enabling gigabit Ethernet and other high-speed protocols over single-mode fiber. Constructed with an aluminium housing and weighing approximately 20 g, the module complies with MSA SFP form-factor standards and is intended for use in networking equipment that supports standard SFP transceivers.

Advantages

The module offers standardized compatibility with SFP cages and interfaces, supporting up to 1.25 Gbps data rate and link distances suitable for long-reach single-mode connections. Its aluminium housing provides a durable, lightweight solution for dense installations. The transceiver supports digital diagnostics (DDM/DOM) when the host hardware provides that functionality, enabling real-time monitoring of supply voltage, laser bias current, transmit power, receive power and temperature for easier maintenance and troubleshooting.

Suitable for

• 1 Gbps Ethernet links over single-mode fiber
• Inter-switch connections and uplinks in data centers and enterprise networks
• Fiber runs up to typical 10 km single-mode distances
• Environments where SFP MSA-compatible transceivers are required

Key specifications

• Form factor: SFP (Small Form-factor Pluggable)
• Wavelength: 1310 nm transmit and receive
• Connector: LC duplex
• Supported data rate: up to 1.25 Gbps
• Fiber type: Single-mode fiber
• Housing material: Aluminium
• Weight: ~0.02 kg
• Digital diagnostics: Supported when host hardware implements DDM/DOM (MSA SFF-8472)

How to use

Insert the SFP transceiver into a compatible SFP port on a switch, router or other networking device while the device is powered according to the vendor's guidance. Secure the LC duplex patch cable to the module's LC connector, ensuring correct polarity and a clean fiber end-face. Verify link status and, if supported by the host, read digital diagnostic parameters to confirm proper optical levels and module health. Follow the network equipment manufacturer's procedures for hot-plugging and firmware compatibility to ensure reliable operation.

Usage recommendations

Use single-mode LC patch cords and, where applicable, appropriate fiber management such as patch panels or adapters to maintain optimal signal quality. Clean connector end-faces before installation and avoid tight bends in fibers. Confirm that the target hardware supports SFP 1000BASE-LX modules and DDM/DOM if diagnostic monitoring is required. For long-term reliability, install in equipment with adequate ventilation and observe manufacturer limits for temperature and power.
