Compact hot-pluggable module simplifies upgrades and maintenance while supporting standard 10G Ethernet links.

## Long description

The SFP+ transceiver CBO DEM-435XT 10Gbps 850nm multimode fiber is a compact hot-pluggable module designed for short-reach 10 Gigabit Ethernet links over multimode fiber. It operates at an 850 nm wavelength and supports data rates up to 10.3125 Gbps, making it suitable for server uplinks, switch-to-switch connections and high-speed links inside data center racks and campus network segments. The module is intended for use in equipment with SFP+ ports that accept industry-standard 10G optical transceivers and simplifies installation and maintenance during network upgrades.
Advantages
This transceiver provides a reliable 10 Gbps optical link with low power consumption and a compact form factor that enables high-density port deployments. As a hot-pluggable SFP+ module, it allows on-the-fly replacement or addition without powering down equipment. The 850 nm multimode design supports short-reach multimode fiber infrastructures commonly used in data centers and enterprise floors, and it is compatible with standard 10G Ethernet signaling for interoperability with a wide range of switches and servers.
Suitable for
Server uplinks and top-of-rack switch connections
Short-reach data center links within racks or between adjacent racks
Campus network aggregation and distribution layers
High-density switch ports where space and power efficiency matter
Key specifications
Data rate: up to 10.3125 Gbps (10G Ethernet compatible)
Wavelength: 850 nm
Fiber type: multimode fiber (MMF)
Form factor: SFP+ hot-pluggable optical transceiver
Typical reach: short-range multimode links (suitable for up to a few hundred meters depending on fiber type and modal bandwidth)
Connector type: duplex LC compatible
Power consumption: low-power SFP+ class module
How to use
Install the transceiver by inserting the SFP+ module into a compatible SFP+ port on a switch, server NIC or other network equipment until it seats firmly. Connect duplex multimode fiber with LC connectors, observing transmit and receive orientation. Verify link status via the equipment’s LEDs or management interface and configure the port for 10G Ethernet if required. The module is hot-pluggable, so it can be inserted or removed while the host device is powered, following the equipment vendor’s guidance for safe handling.
Usage recommendations
Use high-quality OM3 or OM4 multimode fiber for reliable short-reach 10G links and adhere to bend radius and cleanliness best practices for fiber connectors. Check compatibility with the target equipment’s supported transceiver list and update device firmware where recommended to ensure proper link negotiation and monitoring.
