## Summary description

Compact SFP+ optical transceiver BlueOptics ATTJ-BO supporting 10GBASE-SR for short-range 10 Gb/s links over multimode fiber. It uses an 850 nm VCSEL, LC-duplex connector, and reaches up to 300 meters (multimode). Built-in DDM/DOM enables diagnostics; operating range 0°C to +70°C. Suited for switches, servers, and data center uplinks requiring 10Gb short-reach fiber connectivity.

## Long description

BlueOptics ATTJ-BO is a compact SFP+ optical transceiver designed for short-range 10 Gigabit Ethernet links over multimode fiber. The module supports the 10GBASE-SR standard, transmits at 850 nm using a VCSEL source and connects via an LC duplex interface. It is intended for use in network switches, servers and uplink ports in data center and enterprise environments where reliable 10 Gb/s short-reach fiber connectivity is required. The transceiver includes Digital Diagnostic Monitoring (DDM/DOM) to monitor operating parameters and has an operating temperature range from 0°C to 70°C.
Advantages
The module offers a compact SFP+ form factor compatible with 10Gb optical ports and supports multimode fiber links up to 300 meters, providing flexibility for typical rack-to-rack and equipment-to-equipment connections in data centers. Built-in DDM enables real-time monitoring of optical power, temperature and laser bias, which helps maintain link reliability and assists troubleshooting. The LC-duplex connector and 850 nm VCSEL design ensure interoperability with common multimode cabling and established 10GBASE-SR deployments.
Suitable for
 Short-reach 10 Gb/s uplinks between switches and aggregation devices
 Server uplinks and NICs with SFP+ ports in data centers
 Inter-rack connections over multimode fiber within wiring closets
 Network equipment requiring DDM/DOM diagnostics for monitoring
Key specifications
 Data rate: 10 Gigabit Ethernet (10GBASE-SR)
 Wavelength: 850 nm (VCSEL)
 Connector: LC duplex
 Fiber type: Multimode fiber (MMF)
 Maximum reach: up to 300 meters (depending on fiber type and modal bandwidth)
 Form factor: SFP+
 Diagnostics: Digital Diagnostic Monitoring (DDM/DOM)
 Operating temperature: 0°C to 70°C
How to use
Install the SFP+ transceiver into a compatible SFP+ port on a switch, server or other network device, ensuring the module is fully seated and latched. Connect LC-duplex multimode fiber patch cords to the transmit and receive ports, observing correct polarity. Verify link status on the host device and check DDM parameters via the management interface if available. When removing the module, power down or follow hot-swap procedures recommended by the equipment vendor to avoid signal disruption.
Usage recommendations
For optimal performance, use OM3/OM4 multimode fiber for links approaching the maximum reach and maintain clean LC connectors to prevent signal loss. Verify that the host equipment supports SFP+ modules and 10GBASE-SR optics. Monitor DDM values regularly to detect potential issues with optical power or temperature.
