SFP transceiver module BlueOptics SFP-1G-SX-NA-BO 1250 Mbit/s 850 nm

The BlueOptics SFP-1G-SX-NA-BO is a small form-factor fiber optic transceiver module designed for 1 Gbit/s class networks. It supports a maximum data transfer rate of 1250 Mbit/s and operates at an 850 nm wavelength over multimode fiber. The module has an SFP interface and a duplex LC connector, comes in a metal housing with a silver finish, and requires a 3.3 V supply. With a compact, lightweight design (approximately 3 g), it is intended for insertion into compatible SFP ports on switches, routers and storage systems that accept standard 1000Base-SX SFP modules.

Advantages

The BlueOptics SFP-1G-SX-NA-BO provides standardized interoperability through the SFP form factor and MSA-compliant optical characteristics, enabling straightforward replacement or expansion of existing 1000Base-SX links. Its operation at 850 nm is optimized for multimode fiber, offering reliable short-range optical transmission up to typical multimode distances. The module's metal housing improves mechanical durability and thermal behavior, while the low weight and standard electrical interface simplify installation and inventory management.

Suitable for

• Ethernet 1000Base-SX optical uplinks and network aggregation
• Interconnection of switches, routers and storage systems within a data center or campus
• Fibre Channel over Ethernet (FCoE) and other 1 Gbit optical links
• Replacement or spare transceiver inventory for equipment supporting standard SFP 1000Base-SX modules

How to use

Install the BlueOptics SFP-1G-SX-NA-BO by inserting it into a compatible SFP port on the target device until it latches. Connect LC duplex multimode fiber patch cords to the module, paying attention to correct transmit/receive orientation. Ensure the host device supports 1000Base-SX SFP modules and that any vendor-specific port settings are configured as required. Verify link status and speed through the host device management interface and perform basic diagnostics if the DDM/DOM monitoring function is available and supported by the hardware.

Recommendations

Use high-quality multimode fiber patch cords and proper fiber management (patch panels or labeled connections) to achieve expected range and signal quality. Confirm compatibility with the specific switch, router or storage platform and enable digital diagnostic monitoring in supported systems for proactive maintenance.
