## Long description

The SFP+ optical transceiver BlueOptics FN-TRAN-SFP+SRI BO35J856S3D 10G 850nm is a hot-pluggable module designed for 10 Gigabit Ethernet short-range links over multimode fiber. Operating at an 850 nm wavelength, this transceiver supports high-speed uplinks and server connections in data center and enterprise network environments. It is compatible with switch, router and network interface card ports that accept SFP+ form-factor modules and is intended for short-reach fiber runs between racks or within equipment cabinets.
Advantages
The module offers 10 Gbps data rate in a compact SFP+ package that enables flexible deployment and easy replacement without powering down equipment. Operating at 850 nm for multimode fiber provides cost-effective short-range connectivity. The hot-pluggable design reduces maintenance windows and allows rapid upgrades of network links. The transceiver’s standardized form factor ensures broad interoperability with networking hardware that follows SFP+ specifications.
Suitable for
 Data center uplinks between switches and aggregation points
 Server-to-switch connections within racks
 Short-reach multimode fiber links (within the same building or campus)
 Network equipment that supports SFP+ 10G optical modules
Key specifications
 Form factor: SFP+ (hot-pluggable)
 Data rate: 10 Gigabit Ethernet
 Wavelength: 850 nm (VCSEL multimode)
 Fiber type: Multimode fiber (MMF)
 Typical reach: short-range multimode links (designed for intra-building distances)
 Connector type: Duplex LC
How to use
Insert the SFP+ transceiver into a compatible SFP+ port on a switch, router or network interface card until it clicks into place. Connect duplex multimode LC patch cables between the module and the corresponding port on the remote device, observing correct transmit/receive orientation. Ensure connected equipment is configured for 10G operation and that fiber type and link distance are within the module’s intended short-range specifications. Remove the module by releasing any retention latch and gently pulling it from the slot while the equipment is powered, as the module supports hot-plug operation.
Usage recommendations
Use clean LC connectors and follow standard fiber-handling practices to maintain signal quality. Verify compatibility with your network hardware and firmware, and test links after installation to confirm 10G connectivity and expected link budget for multimode fiber.
