Fiber Optic Transceiver CBO ALL4752 1000Base-SX 850nm SFP

CBO ALL4752 is a fiber optic SFP transceiver designed for 1000Base-SX operation at an 850 nm wavelength. It fits the hot-pluggable SFP form factor and provides a standardized optical interface for gigabit Ethernet over multimode fiber. The module is intended for short-range connections such as data center uplinks, switch-to-switch links, and server or storage interconnects within a building or campus environment.

Advantages

The transceiver supports 1000Base-SX protocols and is compatible with standard SFP ports, enabling easy installation and replacement without powering down equipment. Its 850 nm multimode optical design allows low-latency gigabit transmission for short distances, and the compact SFP form factor reduces space requirements in chassis and switches. Compliance with common industry optical parameters ensures interoperability with multimode fiber cabling and a wide range of network equipment.

Suitable for

• Short-range gigabit Ethernet links over multimode fiber
• Data center uplinks and top-of-rack connections
• Switch-to-switch and switch-to-server interconnects within buildings or campuses

Key specifications

• Interface type: SFP (hot-pluggable)
• Data rate: 1000 Mbps (gigabit Ethernet)
• Wavelength: 850 nm
• Medium: Multimode fiber (MMF)
• Typical reach: short-range multimode links (dependent on fiber type and link budget)
• Connector: standard fiber optic duplex connector (LC-compatible interface)

How to use

Insert the transceiver into a compatible SFP port on a switch, router or other network device until it latches. Connect multimode fiber using the appropriate duplex fiber patchcord and ensure correct transmit/receive orientation. After installation, verify link status and data rate on the network device. For removal, disengage the latch and pull the module straight out. Follow standard ESD precautions and keep protective dust caps on unused optical interfaces to avoid contamination.

Recommendations

Use the module with multimode fiber of suitable grade (for example OM1/OM2/OM3/OM4 depending on required reach), keep connectors clean, and verify that the switch or transceiver vendor supports 1000Base-SX SFP modules. Avoid bending fibers beyond their minimum bend radius and operate the equipment within recommended temperature ranges for reliable performance.
