Fiber Optic Transceiver CBO MGB-LA40 1000Base-SX 850nm

The BlueOptics Fiber Optic Transceiver CBO MGB-LA40 1000Base-SX 850nm is a hot-pluggable SFP module designed for Gigabit Ethernet over multimode fiber. It operates at an 850 nm wavelength and supports 1000Base-SX standard-compliant links, making it suitable for short-reach connections in campus, office and data centre environments. The module provides optical transmission for switches, routers and other networking equipment with SFP ports and is intended for reliable, low-latency data connectivity on multimode fiber cabling.

Advantages

This transceiver offers standardized 1000Base-SX performance with easy hot-swap installation and compatibility with SFP ports on a wide range of network devices. Its operation at 850 nm is optimized for multimode fiber, enabling efficient short-distance links with stable signal quality. The compact SFP form factor reduces space requirements and allows flexible port configurations in network racks and edge equipment.

Suitable for

• Gigabit Ethernet links over multimode fiber within buildings
• Short-reach connections between switches, routers and servers
• Campus network segments and wiring closets
• Data centre top-of-rack or access-layer connections

Key specifications

• Standard: 1000Base-SX (Gigabit Ethernet)
• Form factor: SFP (Small Form-factor Pluggable)
• Wavelength: 850 nm
• Fiber type: Multimode fiber (MMF)
• Connection distance: short-reach links (dependent on fiber grade and patching)
• Data rate: 1 Gbps (full-duplex)
• Interface: Optical duplex LC connector

How to use

Install the SFP module into an empty SFP slot on a compatible switch, router or media converter while the host device is powered on or off, observing manufacturer guidance for hot-plugging. Connect multimode fiber patch cords with LC duplex connectors to the module, ensuring correct transmit/receive orientation and appropriate fiber grade for the required distance. Verify link status in the host device management interface and check for proper speed and duplex negotiation. If necessary, adjust port configuration on the switch or router to match the 1000Base-SX operation.

Recommendations

Use multimode fiber of appropriate OM grade and quality patch cords to achieve the specified short-reach distances. Keep SFP optical interfaces covered when not in use to avoid contamination. Ensure compatibility with the network equipment vendor's SFP support list when integrating into managed switches and routers.
