Transceptor SFP BlueOptics BO05C856S5D 1000BASE-SX 850 nm Multimodo

The BlueOptics BO05C856S5D SFP transceiver is a compact, hot-pluggable module designed for 1000BASE-SX gigabit Ethernet over multimode fiber using an 850 nm wavelength. Built to fit standard SFP ports on compatible switches and routers, this transceiver provides short-range optical connectivity suited for data center patching, server uplinks, and campus network links. Its small form factor and plug-and-play operation allow quick replacement or expansion of existing fiber interfaces without powering down equipment.

Advantages

This SFP transceiver supports reliable 1 Gbps optical transmission on multimode fiber at 850 nm and is compatible with standard SFP slots for easy installation. The hot-pluggable design allows adding or replacing modules without interrupting system operation. The module is suitable for short-reach links typical in racks, data centers and campus networks, providing consistent performance for Ethernet traffic and reducing the need for copper cabling where fiber runs are already in place.

Suitable for

• Short-range gigabit connectivity inside data center racks and between adjacent racks
• Server uplinks to switches using multimode fiber
• Campus LAN links and building-to-building connections over multimode fiber
• Replacement of existing 1000BASE-SX SFP modules in compatible network equipment

Key specifications

• Transmission standard: 1000BASE-SX (Gigabit Ethernet)
• Wavelength: 850 nm for multimode fiber
• Form factor: Small Form-factor Pluggable (SFP), hot-pluggable
• Typical reach: short-range links over multimode fiber (designed for data center and campus environments)
• Connector type: LC duplex (standard for multimode SFP modules)
• Data rate: 1 Gbps

How to use

Insert the BlueOptics SFP module into a compatible SFP slot on a powered switch, router or transceiver cage until it seats securely; follow the host device manual for release and locking mechanisms. Connect multimode fiber with LC duplex connectors to the module, ensuring correct polarity and that fiber connectors are clean before insertion. Configure the network device as required for a 1 Gbps optical port; many systems will auto-negotiate the link once the module and fiber are connected. For module removal, follow the host device procedure to safely extract the hot-pluggable SFP.

Recommendations

Use clean, undamaged multimode fiber with appropriate core size (typically 50/125 µm or 62.5/125 µm as supported by the network design) and verify connector cleanliness to avoid signal loss. Match the SFP module to compatible equipment and firmware to ensure interoperability. For reliable links, limit use to short-reach applications intended for 850 nm multimode transmission and consult the switch or router documentation for any specific compatibility notes.
