Fiber Optic Transceiver CBO ALL4761 1000Base-SX 850nm

CBO ALL4761 1000Base-SX 850nm is a fiber optic transceiver module designed for Gigabit Ethernet over multimode fiber. It supports 1000Base-SX operation at an 850 nm wavelength and provides short-range optical connectivity for network devices such as switches, routers and servers. The module is intended for plug-in installation in compatible SFP ports and enables reliable data transmission for network upgrades, datacenter interconnects and campus network links.

Advantages

The transceiver offers straightforward installation and compatibility with standard SFP form-factor ports, reducing deployment time during network upgrades. Its operation at 850 nm over multimode fiber ensures cost-effective short-range links with stable gigabit throughput. The module is engineered for reliable signal integrity and predictable performance in typical enterprise and datacenter environments.

Suitable for

• Short-range Gigabit Ethernet links over multimode fiber (MMF)
• Interconnects between switches, routers and servers
• Datacenter aggregation and access layer connections
• Campus network segments and wiring closets

Key specifications

• Standard: 1000Base-SX (Gigabit Ethernet)
• Wavelength: 850 nm
• Fiber type: Multimode fiber (MMF)
• Form factor: Small Form-factor Pluggable (SFP)
• Link distance: short-range multimode links (dependent on fiber grade and connector losses)
• Connector type: LC duplex (typical for SFP transceivers)

How to use

Install the transceiver into an available SFP slot of a compatible network device while the device is powered on or follow the equipment manufacturer's hot-plug guidelines. Connect LC duplex multimode fiber patch cables to the module, ensuring correct transmit/receive orientation. Configure the network device for 1000 Mbps operation if manual interface settings are required. Monitor link status indicators on the host device to confirm successful optical link establishment and verify signal integrity through standard network diagnostics.

Recommendations

Use appropriate multimode fiber (OM1/OM2/OM3/OM4) and quality LC duplex patch cords, observe proper fiber handling to avoid bend loss, and match transceiver wavelength and fiber type to the intended link distance. Verify compatibility with the host equipment and consider testing links after installation to confirm expected throughput and error rates.
