## Summary description

CBO ET5302-SR is a fiber optic 10G transceiver operating at 850 nm, designed for short-reach multimode links. It provides a compact pluggable interface for 10 Gigabit Ethernet connectivity in data centers and network equipment, enabling reliable high-speed uplinks, server connections, and switch-to-switch links with straightforward installation and hot-swappable convenience.

## Long description

The BlueOptics Fiber Optic 10G Transceiver CBO ET5302-SR 850nm is a small form‑factor, hot‑pluggable module intended for short‑reach multimode fiber links. Operating at 850 nm, this 10 Gigabit transceiver supports 10GBase-SR applications and provides a compact pluggable interface for high‑speed uplinks between switches, server connections, and aggregation points in data centers or enterprise networks. The module is designed for straightforward installation into compatible SFP+ ports and is suitable for environments where reliable, low‑latency 10 Gigabit Ethernet connectivity over multimode fiber is required.
Advantages
The transceiver delivers 10 Gbps throughput with low latency and supports multimode fiber at the 850 nm wavelength for short‑reach links. Its hot‑swappable SFP+ form factor simplifies maintenance and upgrades without powering down equipment. The compact design reduces port space usage, while compatibility with standard 10GBase‑SR interfaces ensures straightforward interoperability with network switches, routers, and servers that accept SFP+ optics. The module is engineered for consistent optical performance within its specified operating range.
Suitable for
Short‑reach 10 Gigabit Ethernet links over multimode fiber in data centers
Server-to-switch and switch-to-switch uplinks in enterprise LANs
Edge and rack aggregation where SFP+ ports are used
Environments requiring hot‑swappable optics for minimal downtime
Key specifications
Data rate: 10 Gbps
Wavelength: 850 nm
Fiber type: Multimode fiber (MMF)
Typical link span: optimized for short‑reach multimode connections
Form factor: SFP+ small form‑factor pluggable
Connector type: Duplex LC
Interface standard: 10GBase‑SR compatible
How to use
Insert the SFP+ transceiver into a compatible SFP+ port on the switch, server NIC, or other network device while the host is powered on if hot‑swap capability is needed. Connect duplex multimode fiber with LC connectors to the transceiver ports, observing correct transmit and receive orientation. Verify link status via the host device LEDs or management interface and confirm negotiated 10 Gbps operation. Remove the module by gently extracting it from the port, using any installed pull tab or release mechanism as provided by the host hardware.
Usage recommendations
Use multimode fiber of appropriate type and attenuation (for example OM3/OM4) and maintain correct fiber handling to avoid bends and contamination. Confirm device compatibility with the host vendor’s supported transceiver list and keep firmware and drivers up to date to ensure stable 10G operation.
