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

The BlueOptics SFP-1G-SX-NK-BO is a compact SFP transceiver module designed for multimode fiber networks. It supports a maximum data transfer rate of 1250 Mbit/s and operates at a wavelength of 850 nm. Housed in a metal case and powered by 3.3 V, the module weighs approximately 3 g and provides an LC duplex interface compatible with common SFP ports. The transceiver follows MSA-compatible form factors and is suitable for 1000Base-SX applications over multimode fiber.

Advantages

This SFP module provides stable gigabit-capable optical connectivity in a small, industry-standard package. The metal housing offers mechanical durability and thermal stability while the 850 nm multimode optic supports short-range high-speed links. Low weight and standard SFP form factor simplify installation and replacement in switches, routers and storage systems. Designed to be compatible with widely used 1000Base-SX implementations, the module supports digital diagnostic monitoring when the host platform provides that feature.

Suitable for

• Short-range multimode fiber links in Ethernet networks (1000Base-SX)
• Interconnects between switches, routers and storage devices
• Data center patching and rack-to-rack connections
• Upgrades or replacements in equipment that accepts SFP optical transceivers

Key specifications

• Interface type: SFP (small form-factor pluggable)
• Data rate: up to 1250 Mbit/s (1.25 Gbit/s)
• Operating wavelength: 850 nm
• Connector: LC duplex (multimode fiber)
• Power supply: 3.3 V
• Housing: metal
• Weight: approx. 3 g

How to use

Insert the SFP module into an available SFP port on compatible network equipment until it latches; avoid touching the optical interfaces. Connect LC duplex multimode fiber patch cords with correct polarity to the transceiver. Ensure the host device is powered and configured for the intended 1000Base-SX link. If the platform supports digital diagnostic monitoring (DDM/DOM), enable or query the diagnostic interface to monitor supply voltage, laser bias/current, transmit/receive power and module temperature. Follow your equipment vendor’s hot-swap and handling procedures when installing or removing the transceiver.

Recommendations

Use high-quality multimode fiber patch cords and, where applicable, patch panels to maintain optimal signal performance. Verify compatibility with your host hardware and firmware before deployment and, if monitoring is required, confirm the DDM/DOM support in the host device. Protect unused connectors with dust caps and observe ESD precautions during handling.
