## Long description

BlueOptics BO35J856S3D is an SFP+ transceiver module designed for short-range 10 Gigabit Ethernet links over multimode fiber. The module uses an 850 nm VCSEL light source and an LC duplex connector to support 10GBASE-SR applications with a maximum reach of up to 300 meters on suitable multimode cabling. It is intended for insertion into compatible SFP+ ports on switches, servers and other network appliances and operates within an ambient temperature range of 0°C to 70°C.
Advantages
The transceiver provides a compact SFP+ form factor that supports high-density installations and simplifies port upgrades to 10G. Its 850 nm multimode operation is optimized for cost-effective short-reach links in data centers and enterprise networks. The LC duplex interface ensures reliable duplex communication with common multimode patch cords, and the module’s operating temperature range allows deployment in standard controlled environments without additional cooling measures.
Suitable for
 Short-range 10 Gigabit Ethernet connections in data centers
 Inter-switch links and uplinks between network equipment
 Server-to-switch connections over multimode fiber
 Network appliance 10G SFP+ ports where LC duplex multimode transceivers are required
Key specifications
 Form factor: SFP+ (10G)
 Standard: 10GBASE-SR
 Wavelength: 850 nm
 Connector: LC duplex
 Fiber type: Multimode fiber (MMF)
 Maximum reach: up to 300 meters (on appropriate multimode cabling)
 Operating temperature: 0°C to 70°C
How to use
Install the SFP+ module into an empty SFP+ port on a compatible switch or network device until it clicks into place, then secure the module according to the device manufacturer’s instructions. Connect LC duplex multimode patch cords to the module and the corresponding port on the remote equipment, ensuring correct transmit/receive orientation. Verify link status and speed through the host device management interface and confirm that the multimode fiber type and patch cords meet the requirements for 10GBASE-SR to achieve the specified reach.
Usage recommendations
Use multimode fiber with appropriate modal bandwidth (e.g., OM3/OM4) for reliable 300 m reach and test links after installation. Avoid bending or stressing fiber connectors and follow ESD precautions when handling the transceiver. Check the compatibility list of the host device before deployment to ensure full functionality and diagnostic support.
