SFP Transceiver BlueOptics BO05C856S5D 1000BASE-SX Multimode 850 nm

The BlueOptics BO05C856S5D SFP transceiver is a hot-pluggable module that supports 1000BASE-SX operation over multimode fiber at an 850 nm wavelength. Designed for use in standard SFP slots, this compact transceiver enables short-range gigabit Ethernet links suitable for switches, routers and other network appliances. It provides a simple way to add or replace multimode fiber connectivity for data center uplinks, campus interconnects and server-to-switch connections without requiring device shutdown.

Advantages

This SFP transceiver offers hot-pluggable installation and compatibility with standard SFP ports, making upgrades and maintenance straightforward. Its 850 nm multimode operation is optimized for short-distance gigabit links, while the compact form factor reduces space usage in network devices. The module is engineered for stable physical layer performance to support reliable data transmission in short-reach environments.

Suitable for

• Short-range gigabit Ethernet links over multimode fiber
• Data center uplinks and switch-to-switch connections
• Campus network segments and building-to-building links within short distances
• Server-to-switch or appliance connectivity in rack environments

Key specifications

• Interface: Small Form-factor Pluggable (SFP)
• Data rate: 1 Gbit/s (1000BASE-SX)
• Optical mode: Multimode fiber
• Wavelength: 850 nm
• Reach: short-range multimode links (typical multimode distances)
• Connector type: LC duplex
• Hot-pluggable design for in-service replacement

How to use

Insert the transceiver into a compatible SFP slot on a switch, router or network appliance until it clicks into place. Connect an LC-terminated multimode fiber patch cable to the module’s duplex LC connector, observing transmit and receive polarity. The device should be recognized by the host port and negotiate 1000BASE-SX operation automatically; configure the network equipment as required for link activation and VLAN or port settings. To remove, power down the link if recommended by the equipment vendor, then press the release tab and withdraw the module carefully.

Usage recommendations

Use OM3 or OM4 multimode fiber for improved margin and reliable short-reach performance; ensure fiber cleanliness and correct polarity before link bring-up. Verify compatibility with the host device and follow vendor guidelines for hot-plug operations and fiber handling to maintain signal integrity.
