SFP transceiver module BlueOptics SP-03-IR1-CDFN-BO 155 Mbit/s 1310 nm

The BlueOptics SP-03-IR1-CDFN-BO is an SFP fiber optic transceiver module engineered for single-mode optical links. It supports a maximum data transfer rate of 155 Mbit/s at a wavelength of 1310 nm and uses an LC duplex connector for simultaneous transmit and receive over separate fibers. The module features a metal housing, a compact SFP form factor with a 3.3 V supply voltage and a lightweight construction of approximately 2 g, making it suitable for integration into switches, routers and other networking hardware that follow MSA SFP standards.

Advantages

The module provides reliable single-mode transmission up to the specified range for 100BASE-LX applications while maintaining low power consumption due to its 3.3 V operation. Its metal housing contributes to mechanical durability and thermal dissipation. Designed to be compatible with major hardware platforms that support the corresponding 100BASE-LX SFP, the transceiver includes digital diagnostics support (DDM/DOM) when the host system exposes that function, enabling real-time monitoring of supply voltage, laser bias current, optical output and input power, and temperature.

Suitable for

• 100BASE-LX Ethernet links over single-mode fiber
• Inter-switch and switch-to-router uplinks
• Fibre Channel over Ethernet and legacy SDH/SONET applications up to 155 Mbit/s
• Network equipment requiring MSA-compliant SFP modules with LC duplex connectors

Key specifications

• Interface type: SFP (small form-factor pluggable)
• Maximum data transfer rate: 155 Mbit/s
• Wavelength: 1310 nm (single-mode)
• Connector: LC duplex
• Supply voltage: 3.3 V
• Housing: metal
• Weight: approx. 2 g

How to use

Install the transceiver into an SFP slot on a compatible switch, router or other network device while the host device is powered down or according to the vendor’s hot‑swap guidelines. Connect LC duplex single‑mode fiber patch cords to the module, ensuring correct orientation of transmit and receive fibers. Confirm that the host device supports 100BASE‑LX operation and, if required, enable or check digital diagnostics (DDM/DOM) in the device management interface to monitor operational parameters. Follow standard electrostatic discharge (ESD) precautions during handling and avoid bending fibers beyond their minimum bend radius.

Recommendations

Use high-quality single-mode LC duplex patch cords and, when possible, test compatibility in the target hardware platform before large-scale deployment. Ensure the host equipment supports DDM/DOM if remote monitoring is needed, and maintain clean connector endfaces to preserve signal integrity and link availability.
