## Summary description

CBO 455883-B21-BO is an SFP+ network transceiver module with 10,000 Mbit/s data rate and 850 nm wavelength. Designed for short-range multimode fiber links, it enables high-speed uplinks and server-to-switch connections. Hot-pluggable SFP+ form factor supports fast replacement and upgrades, ideal for data centers and enterprise networks.

## Long description

CBO 455883-B21-BO is an SFP+ network transceiver module designed for 10,000 Mbit/s links over multimode fiber using an 850 nm wavelength. The module supports short-range connections typical for server-to-switch uplinks, top-of-rack links and aggregation ports in data center or enterprise LAN environments. Its hot-pluggable SFP+ form factor allows quick replacement or upgrades without powering down the host device.
Advantages
The transceiver provides a compact 10 Gbps interface with low power consumption and standardized electrical and optical characteristics compatible with SFP+ ports. The 850 nm multimode design enables economical short-range connectivity over commonly used multimode fibres and patchcords. Hot-pluggability and a standardized connector make installation and maintenance straightforward in rack-mounted and modular network equipment.
Suitable for
 10 Gbps server-to-switch uplinks in data centers
 Top-of-rack and aggregation links over multimode fiber
 High-speed connections between switches and storage arrays within the same building
 Short-range fiber upgrades where SFP+ ports are available
Key specifications
 Form factor: SFP+ (hot-pluggable)
 Data rate: 10,000 Mbit/s (10 Gbps)
 Optical wavelength: 850 nm
 Fiber type: multimode fiber (short-range links)
 Connector type: duplex LC
 Typical application distance: short-range multimode links (dependent on fiber grade and transceiver power)
How to use
Insert the SFP+ transceiver into a compatible SFP+ port on a switch, server NIC or optical module slot while the host is powered on, ensuring correct orientation until it seats firmly. Connect duplex multimode LC patchcords between transceivers on each end, observing correct transmit/receive pairing. After insertion, check link LEDs and host interface status to verify negotiation at 10 Gbps. If required, configure the host device or switch ports for appropriate speed and duplex settings and confirm fiber type and distance match the transceiver's short-range design.
Usage recommendations
Use high-quality OM3/OM4 multimode fiber and certified LC duplex patchcords to achieve reliable 10 Gbps links at short distances. Avoid bending the fiber beyond manufacturer bend-radius limits and ensure clean fiber endfaces before insertion to prevent signal loss. For replacement or upgrades, use the hot-pluggable capability to swap transceivers without system downtime, but follow the host vendor’s guidance for safe hot-swapping procedures.
