Fiber optic transceiver CBO AFCT-5765ALZ 1000Base-SX 850nm

CBO AFCT-5765ALZ 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 a standardized optical interface for switches, routers and other network equipment. The module is intended for short-range fiber links and can be used to restore or upgrade 1 Gbps fiber ports in data centers, server rooms and access networks.

Advantages

The transceiver provides industry-standard compatibility with equipment that accepts 1000Base-SX modules, enabling straightforward replacement and upgrades without changes to existing hardware configuration. Its 850 nm multimode design offers low-latency 1 Gbps connectivity over short distances and supports stable optical transmission for typical enterprise and campus fiber runs. The module’s form factor and thermal characteristics are suitable for rack-mounted network devices and allow plug-and-play installation with minimal downtime.

Suitable for

• Short-range Gigabit Ethernet links over multimode fiber in data centers and server rooms
• Replacing faulty or incompatible SFP modules in switches and routers
• Upgrading copper ports to 1 Gbps optical connections
• Campus and enterprise access links where 850 nm multimode optics are standard

Key specifications

• Data rate: 1 Gbps (1000Base-SX)
• Wavelength: 850 nm
• Fiber type: Multimode fiber (MMF)
• Typical reach: short-range multimode links (industry standard distances for 850 nm optics)
• Form factor: hot-pluggable small form-factor pluggable (SFP) style module

How to use

Insert the transceiver into a compatible SFP slot on the switch, router or network device while the device is powered according to the manufacturer’s instructions for hot-pluggable modules. Connect multimode fiber patch cables with appropriate LC connectors to the module’s optical ports, ensuring correct polarity. Verify link status and speed on the network device management interface and perform any required configuration changes such as enabling the port or setting link parameters. For safe removal, disable the port or follow the device procedure before extracting the module.

Recommendations

Use certified multimode fiber patch cables and maintain clean connector endfaces to ensure optimal optical performance. Verify compatibility with the host device’s supported SFP modules and firmware, and observe manufacturer guidelines for operating temperature and handling to preserve module reliability.
