## Summary description

Compatible SFP+ optical transceiver BlueOptics BO35J856S3D (R7D05A-BO) for 10GBASE-SR links. Uses LC-duplex connector and multimode fiber at 850 nm wavelength, supporting up to 300 meters. Designed for data center and enterprise short-range 10 Gigabit Ethernet connections, operating temperature 0°C to +70°C.

## Long description

The SFP+ Transceiver BlueOptics BO35J856S3D is a compact optical module designed for 10GBASE-SR short-range Ethernet links. It uses an LC-duplex connector and transmits at an 850 nm wavelength over multimode fiber, supporting link distances up to 300 meters. The transceiver is intended for installation in compatible SFP+ ports of switches, routers and media converters used in data centers and enterprise networks. The operating temperature range is 0°C to 70°C, making it suitable for standard indoor network environments.
Advantages
This SFP+ transceiver provides a reliable 10 Gigabit Ethernet connection over multimode fiber with a standardized LC-duplex interface, enabling straightforward installation and hot-plug capability. Its support for 850 nm short-range transmission and up to 300 m reach makes it a practical choice for rack-to-rack and intra-data-center links. The module’s compact SFP+ form factor conserves port space while offering full 10 Gbps throughput, and the specified operating temperature range aligns with common server room conditions.
Suitable for
10 Gigabit Ethernet short-range links in data centers
Inter-rack and intra-rack connectivity over multimode fiber
Upgrading switch or media converter ports to 10GBASE-SR
Enterprise networks requiring LC-duplex multimode connections at 850 nm
When it may not be suitable
This transceiver is designed specifically for short-range multimode fiber and 850 nm operation; it is not suitable for single-mode fiber or long-haul links. It will not support extended-distance requirements beyond the specified 300 m over multimode fiber nor functions that require different wavelengths or connector types.
Key specifications
Protocol: 10GBASE-SR (short-reach 10 Gigabit Ethernet)
Form factor: SFP+ (small form-factor pluggable plus)
Connector type: LC-duplex
Fiber type: Multimode fiber
Wavelength: 850 nm
Maximum reach: up to 300 meters (depending on fiber grade and installation)
Operating temperature: 0°C to 70°C
Data rate: 10 Gbps
How to use
Install the SFP+ transceiver into a compatible SFP+ slot on a switch, router or media converter while the device is powered on or off according to the host hardware’s hot-plug guidance. Connect multimode LC-duplex patch cables to the module, observing transmit/receive orientation. Verify link status and speed through the host device’s management interface or LEDs. For best performance, use appropriate multimode fiber (for example OM3/OM4 where higher margins are needed) and maintain clean fiber connectors to avoid signal degradation.
What to consider before purchase
Ensure host device compatibility with third-party SFP+ modules and support for 10GBASE-SR
Confirm the installed multimode fiber type and the required maximum link distance
Check connector type (LC-duplex) and cable inventory to match the transceiver
Verify operating temperature range fits your deployment environment
Usage recommendations
For reliable 10GBASE-SR links, pair the transceiver with appropriate multimode fiber (OM3/OM4 recommended for full 300 m reach), keep connector endfaces clean, and monitor link status after installation. When mixing brands, confirm interoperability with the host hardware to avoid link negotiation issues.
