SFP-transceivermodule BlueOptics SFP-1G-SX-CT-BO 1250 Mbit/s 850 nm

The BlueOptics SFP-1G-SX-CT-BO is a single‑port SFP fiber optic transceiver designed for 1000Base‑SX applications. It supports a maximum data rate of 1250 Mbit/s, operates at an 850 nm wavelength and uses an LC duplex connector for multimode fiber links. The module features a metal housing, a compact form factor and a 3.3 V supply, making it suitable for integration into switches, routers and other network devices that accept SFP modules.

Advantages

This SFP transceiver provides standardized interoperability with MSA‑compliant SFP ports and supports simultaneous transmit and receive over separate fibers via the LC duplex interface. Its compact metal enclosure contributes to thermal stability and durability while the low weight simplifies handling and installation. The module is designed to support Ethernet and similar high‑speed protocols up to 1.25 Gbit/s over multimode fiber with distances appropriate for 850 nm 1000Base‑SX links.

How to use

Ensure that the host device supports MSA‑compliant SFP transceivers and 850 nm 1000Base‑SX operation before installation. With the network interface powered down or as recommended by the equipment vendor, insert the module into an SFP slot until it latches. Connect LC duplex multimode fiber patch cords to the transmit and receive ports, taking care to match TX and RX between endpoints. After insertion, verify link status and speed in the host device management interface and confirm that any required firmware or port settings are configured for 1 Gbit/s operation.

Recommendations

Use high‑quality OM3/OM4 multimode fiber for improved reach and margin, and install dust caps when the transceiver is not in use. Confirm digital diagnostic (DDM/DOM) support on the host platform to enable real‑time monitoring of optical parameters where available, and follow the equipment manufacturer’s handling and electrostatic discharge guidelines during installation.
