SFP transceiver module BlueOptics 1KGT038918R0001-BO 1250 Mbit/s

The BlueOptics 1KGT038918R0001-BO 1250 Mbit/s SFP transceiver module is a compact fiber optic interface designed for 1.25 Gigabit Ethernet links. It supports a maximum data transfer rate of 1250 Mbit/s and a maximum transfer distance of up to 40,000 m using single-mode fiber with an LC (UPC) connector. The module has a small metal housing in a silver finish, with dimensions of 13.9 mm (width) x 58.4 mm (depth) x 12.6 mm (height) and a lightweight construction of approximately 0.03 kg. With a mean time between failures (MTBF) of 1,000,000 hours and a low input voltage requirement, it is intended for reliable, space-efficient fiber connections in network equipment that accepts SFP form-factor transceivers.

Advantages

The transceiver offers a standardized SFP form factor for broad compatibility with switches, routers and media converters that accept SFP modules. Its support for 1.25 Gigabit Ethernet and a long maximum transfer distance make it suitable for both local and long-reach fiber links. The compact metal housing and low weight simplify installation in dense rack environments while the specified MTBF indicates long-term operational durability.

Suitable for

• 1.25 Gigabit Ethernet fiber uplinks in switches and routers
• Long-reach single-mode fiber links up to 40 km
• Media converters and SFP-capable network appliances
• Environments requiring compact SFP modules with LC (UPC) connectors

How to use

Ensure compatible SFP-capable equipment and a matching fiber type before installation. Power down the host device if recommended by the manufacturer, align the module with the SFP port and insert until it seats and latches securely. Connect an LC (UPC) terminated fiber patch cable to the transceiver, observing proper fiber handling and cleanliness. Restore power to the host device if it was powered down and verify link status and data rate through the device management interface or diagnostics. Follow the host equipment guidelines for hot-swap insertion if supported.

Recommendations

Handle optical connectors carefully and clean end faces before connection to prevent signal loss. Use single-mode fiber when deploying links near the maximum specified distance and verify compatibility of wavelengths and transceiver settings within the network. Store the module with protective caps when not in use and follow ESD protection practices during installation.
