SFP transceiver CBO AFCT-5765LZ 1000Base-SX 850nm multimode fiber

The BlueOptics SFP transceiver CBO AFCT-5765LZ 1000Base-SX 850nm multimode fiber is a compact, hot-pluggable module designed for Gigabit Ethernet links over multimode fiber. Supporting the 1000Base-SX standard at a wavelength of 850 nm, this transceiver provides short-reach optical connectivity for data centers, campus networks and enterprise environments. It fits standard SFP ports and enables replacement or upgrade of existing SFP interfaces to restore or extend gigabit fiber links.

Advantages

This SFP transceiver offers stable gigabit performance with low power consumption and hot-pluggable convenience, allowing module swaps without powering down network equipment. Its multimode 850 nm design is optimized for short-reach links, reducing the need for costly single-mode optics for intra-building connections. The compact SFP form factor ensures broad compatibility with switches and routers that accept standard SFP modules.

Suitable for

• Short-reach fiber links within data centers and server rooms
• Campus and building backbone connections over multimode fiber
• Upgrading or replacing SFP ports on switches, routers and media converters
• Gigabit Ethernet links between network closets and edge devices

Key specifications

• Interface: SFP hot-pluggable form factor
• Data rate: 1.25 Gbit/s (1000Base-SX compatible)
• Wavelength: 850 nm for multimode fiber
• Optical range: short-reach multimode links (typical distances depend on fiber type and modal bandwidth)
• Connector type: duplex LC-compatible fiber interface
• Power consumption: low-power SFP class module

How to use

Insert the transceiver into an empty SFP slot on a compatible switch, router or media converter until it clicks into place. Connect duplex multimode fiber using LC patch cords, observing correct transmit/receive orientation. After installation, verify link status on the host device and configure the port for 1000 Mbps full duplex if required by the equipment. To remove the module, power down the port if recommended by the device manufacturer or use the hot-swap procedure supported by the network equipment.

Usage recommendations

For reliable performance, use high-quality multimode fiber (OM3/OM4 recommended for longer short-reach distances), keep connectors and ports clean, and check compatibility lists of the network equipment. Monitor link LEDs and device logs after installation to confirm stable operation.
