Transceiver CBO MGB-LA20 Fiber Optic 1000Base-SX 850nm

CBO MGB-LA20 Fiber Optic 1000Base-SX 850nm is a compact Gigabit Ethernet transceiver designed for multimode fiber links. The module supports 1000Base-SX operation at a wavelength of 850 nm and provides a standard SFP form factor that fits network switches, routers and servers equipped with SFP ports. It is intended for short-reach fiber connections and can be used to replace faulty modules or to expand fiber connectivity while preserving 1 Gbps performance.

Advantages

This transceiver offers compatibility with active networking equipment that accepts SFP 1000Base-SX modules and supports multimode fiber optics, enabling reliable short-distance data transmission. Its compact design and standardized interface simplify installation and replacement without requiring changes to existing hardware. The 850 nm wavelength and Gigabit throughput provide predictable performance for campus networks, data center uplinks and enterprise access links.

Suitable for

• Short-reach Gigabit Ethernet links over multimode fiber (MMF)
• Replacing failed SFP modules in switches and servers
• Expanding fiber ports in access switches and aggregation devices
• Data center cross-connects and server uplinks within the same building or campus

Key specifications

• Transmission standard: 1000Base-SX (Gigabit Ethernet)
• Operating wavelength: 850 nm
• Form factor: SFP (small form-factor pluggable)
• Fiber type: Multimode fiber (MMF)
• Typical reach: short-reach links (distance depends on fiber type and modal bandwidth)
• Connector type: LC duplex compatible

How to use

Ensure the network device is powered and compatible with SFP 1000Base-SX modules before installation. Remove protective caps from the transceiver and the fiber connectors, align and insert the module into an available SFP slot until it clicks into place. Connect LC duplex fiber patch cables to the transceiver, observing transmit and receive orientation. After insertion, verify link status on the host device and confirm negotiated speed of 1 Gbps. To remove the module, power down or follow hot-swap procedures recommended by the equipment vendor, then press the release tab and pull the transceiver straight out.

Recommendations

Use multimode fiber with appropriate modal bandwidth (OM1/OM2/OM3/OM4) suitable for the required link distance, keep fiber connectors clean to avoid signal loss, and consult the host device manual for supported SFP modules and hot-swap guidelines to ensure reliable operation.
