SFP fiber optic transceiver CBO AFCT-5705ALZ 1000Base-SX 850nm

CBO AFCT-5705ALZ 1000Base-SX 850nm is an SFP fiber optic transceiver designed for Gigabit Ethernet over multimode fiber. The module provides a hot-pluggable small form-factor interface for switches, routers and media converters, enabling short-reach fiber uplinks at 850 nm wavelength. The transceiver follows the 1000Base-SX standard and is intended to maintain compatibility with standard SFP ports while replacing failed modules or adding fiber connectivity to network equipment.

Advantages

The SFP transceiver offers a compact, hot-swappable design that simplifies installation and maintenance without powering down the host device. Operating at 850 nm for short-reach multimode links, it supports Gigabit Ethernet data rates and standard SFP form factor interoperability. The module is suitable for cost-effective fiber deployment where copper is impractical or longer distance than copper is required, and it enables predictable performance when used with compatible multimode fiber and hardware.

Suitable for

• Short-reach Gigabit Ethernet links over multimode fiber (e.g., within buildings or campus networks)
• Upgrading switches, routers or media converters to add fiber ports
• Replacing failed or incompatible SFP modules in existing equipment
• Data center patching and network aggregation on multimode fiber runs

Key specifications

• Standard: 1000Base-SX for Gigabit Ethernet
• Wavelength: 850 nm optimized for multimode fiber
• Form factor: Small Form-factor Pluggable (SFP), hot-pluggable
• Interface: Multimode fiber LC connector compatible
• Typical reach: Short-reach multimode distances (dependent on fiber type and modal bandwidth)
• Supported data rate: 1 Gbps (Gigabit Ethernet)

How to use

Power off is not required for installation: insert the SFP transceiver into an available SFP slot on a compatible switch, router or media converter until it seats firmly. Connect the multimode LC patch cable to the transceiver and secure the other end to the corresponding device. Confirm link and activity status through the host device indicators or management interface. If required, configure the host port for Gigabit operation and verify fiber type and duplex settings in the network equipment to ensure optimal link performance.

Recommendations

Use multimode fiber with appropriate modal bandwidth for short-reach 850 nm links and verify compatibility with the host device vendor when mixing third-party SFP modules. Keep dust caps on connectors when not in use, and follow standard fiber-handling practices to avoid contamination or damage to the optical interfaces.
