SFP transceiver module BlueOptics SFP-1G-SX-DE Fiber optic 1250 Mbit/s 850 nm

The BlueOptics SFP-1G-SX-DE is an SFP fiber optic transceiver module engineered for short-range gigabit links. Supporting a maximum data transfer rate of 1250 Mbit/s and operating at an 850 nm wavelength, this compact module provides physical-layer connectivity for switches, routers and media converters with SFP ports. The transceiver's small form factor and 20 g weight make it suitable for dense installations where space and port density matter. The silver housing offers a standardized, rack-friendly appearance while ensuring compatibility with common multimode fiber applications.

Advantages

The module supports standard SFP interfaces and provides a simple hot-pluggable solution for adding or replacing fiber ports without powering down equipment. Its 850 nm wavelength and 1250 Mbit/s rate are optimized for short-reach multimode fiber links, delivering stable physical-layer performance for LAN and intra-building connections. The lightweight, compact design eases handling and installation in crowded networking racks and enclosures.

Suitable for

• Short-range multimode fiber connections (desktop to rack or inter-rack)
• Upgrading switch or router ports to fiber SFP links
• Fiber patch panels and media converters with SFP slots
• Local area network backbone segments and server uplinks

How to use

Insert the BlueOptics SFP-1G-SX-DE into a compatible SFP port on network equipment while the device is powered according to the equipment manufacturer's instructions for hot-pluggable modules. Use appropriate multimode fiber patch cords and ensure correct fiber connector types and polarity. Verify link status on the host device and configure network settings (speed/duplex or auto-negotiation) if required by the equipment. When removing the transceiver, follow the host device's safe removal procedure to avoid damaging the module or the port.

Recommendations

Use the module with multimode fiber of suitable grade (e.g., OM1/OM2/OM3 depending on distance requirements), maintain clean fiber connectors to prevent signal loss, and consult the host equipment's compatibility list for interoperable SFP modules. Avoid exposing the transceiver to excessive dust or mechanical stress during installation.
