SFP-transceiver BlueOptics SLC40-DDM-BO 155 Mbit/s 1310 nm

The BlueOptics SLC40-DDM-BO is an SFP fiber optic transceiver supporting data rates up to 155 Mbit/s and operating at a wavelength of 1310 nm. Housed in a silver metal casing and weighing approximately 3 g, the module uses a standard SFP form factor with an LC duplex connector and is designed for single-mode fiber links. It features a 3.3 V supply and includes Digital Diagnostic Monitoring (DDM) functionality for live measurement of operating parameters when used in compatible equipment.

Advantages

The transceiver offers compatibility with devices that accept SFP modules and supports long-reach single-mode connections up to typical 40 km distances when deployed under appropriate conditions. Built to MSA standards, the module provides optical transmit and receive functions at 1310 nm and is supplied in a durable metal housing for mechanical stability. Integrated DDM enables remote monitoring of supply voltage, laser bias current, optical output and input power, and temperature in systems that support the feature.

Suitable for

• Single-mode fiber Ethernet links up to 155 Mbit/s
• Long-distance connections between switches and routers (typical 40 km)
• Replacement or upgrade of SFP ports in networking equipment that supports SLC40-DDM compatible modules
• Environments requiring DDM/DOM monitoring for optical link diagnostics

Key specifications

• Interface type: SFP (LC duplex)
• Maximum data transfer rate: 155 Mbit/s
• Operating wavelength: 1310 nm
• Fiber type: single-mode
• Supply voltage: 3.3 V

How to use

Insert the SFP transceiver into an available SFP slot on compatible network equipment until it seats securely. Connect an LC duplex single-mode fiber patch cable, observing transmit/receive orientation. Ensure the host device supports the required data rate and DDM feature to access diagnostic parameters. Configure the network interface on your device as needed for the intended Ethernet or relevant protocol settings, then verify link status and optical power levels via the host management interface or the module's DDM readings.

Recommendations

Use single-mode LC duplex patch cords and maintain clean fiber connectors to preserve signal quality. Confirm host compatibility with SLC40-DDM-BO modules and enable DDM/DOM support in the device firmware to monitor optical parameters. For long-distance links, follow vendor guidelines for loss budget and test the link with appropriate optical power meters or network diagnostics before deployment.
