## Long description

BlueOptics SFP+ transceiver BO35J856S3D 10G 850nm multimode is a compact optical module for 10 Gigabit Ethernet links over multimode fiber. Designed for use in SFP+ ports, the transceiver supports short-range data transmission at a wavelength of 850 nm and is intended for deployment in data center server uplinks, switch-to-switch connections and campus network interconnects. The module fits standard SFP+ sockets and allows hot-swap replacement without interrupting powered equipment.
Advantages
This 10G multimode SFP+ transceiver delivers reliable short-range connectivity with low power consumption and stable optical performance. Its form factor ensures compatibility with a wide range of switches, routers and media converters that accept SFP+ modules. The 850 nm VCSEL-based design provides cost-effective transmission for multimode fiber runs, and the module’s compact plug-and-play nature enables quick installation and maintenance.
Suitable for
 Short-range 10 Gigabit Ethernet links within data centers
 Server uplinks and switch stacking over multimode fiber
 Campus network backbone segments and horizontal cross-connects
 Media converters and network equipment requiring SFP+ interfaces
Key specifications
 Interface: SFP+ form factor for 10 Gigabit Ethernet
 Wavelength: 850 nm (multimode)
 Fiber type: Multimode fiber (MMF)
 Typical reach: short-range multimode links (commonly up to 300 m on OM3/OM4 depends on fiber type)
 Data rate: 10.3125 Gbps (10G Ethernet)
 Operating mode: Hot-pluggable
 Optical transmitter: VCSEL-based multimode source
How to use
Insert the transceiver into a compatible SFP+ port until it clicks into place, then connect the multimode duplex fiber cable with the correct LC connectors. Ensure the networking device is configured for a 10 Gigabit link and verify link status through the switch or router management interface. For hot-swap replacement, remove the module using the release latch while observing ESD precautions and insert the new module without powering down connected equipment if the device supports hot swapping.
Usage recommendations
Use multimode fiber of appropriate grade (for example OM3 or OM4) to achieve expected reach and performance. Observe ESD precautions when handling the transceiver, keep optical connectors clean and use dust caps when not connected to prevent contamination. Verify compatibility with the host device’s SFP+ port and firmware to ensure proper operation.
