SFP transceiver module BlueOptics SFP-23A-BO 1250 Mbit/s Fiber optic

The BlueOptics SFP-23A-BO is a single‑mode fiber optic SFP transceiver module designed for 1250 Mbit/s (1.25 G) data transmission. Housed in a durable metal case and weighing just 3 g, the module follows MSA SFP form‑factor standards and uses an LC simplex connector for optical links. The transceiver implements a bi‑directional 1000BASE‑BX‑U topology with separate transmitter and receiver wavelengths to enable long‑reach single‑fiber operation over distances up to 40 km when used with appropriate fiber and equipment.

Advantages

The module supports a 3.3 V interface and a maximum data rate of 1250 Mbit/s while maintaining a compact, robust metal enclosure for reliable operation in networking environments. It is manufactured to MSA standards and uses high‑quality optical and electronic components to provide stable performance and long operational lifetime. The transceiver also supports DDM/DOM diagnostic monitoring (MSA SFF‑8472 compliant) for real‑time parameters such as supply voltage, laser bias current, transmit output power, receive input power and temperature, facilitating remote maintenance and troubleshooting.

Suitable for

• Fiber uplinks between switches and routers over single‑mode fiber
• Long‑reach Ethernet links up to 40 km
• Data center and telecom interfaces supporting 1000BASE‑BX‑U
• Replacement or expansion modules in hardware that supports RAD SFP‑23A compatible transceivers

How to use

Install the SFP transceiver into a compatible SFP slot on your switch, router or other network device following the device manufacturer’s hot‑swap and handling instructions. Connect an LC simplex single‑mode fiber patch cord to the transceiver and the remote endpoint, ensuring correct orientation for bi‑directional single‑fiber operation. Verify link status in the host device and, if supported, read DDM/DOM values for link diagnostics. Observe electrostatic discharge (ESD) precautions and avoid touching optical interfaces; keep dust caps on unused connectors until installation.

Usage recommendations

Use single‑mode fiber with appropriate attenuation and link budget to achieve the specified reach. Confirm that the host hardware supports RAD SFP‑23A compatible 1000BASE‑BX‑U transceivers and that DDM/DOM functions are enabled if real‑time diagnostics are required. Store and handle transceivers in ESD‑safe conditions and clean fiber connectors before mating to ensure optimal signal quality.
