SFP fiber transceiver CBO SFP-GLSD-10A-A 1000Base-SX 850nm multimode

The CBO SFP-GLSD-10A-A 1000Base-SX 850nm multimode SFP fiber transceiver is a hot-pluggable optical module designed for short-range Gigabit Ethernet links over multimode fiber. It supports 1000Base-SX operation at a wavelength of 850 nm and is intended for installation in standard SFP ports on switches, routers and media converters. The transceiver provides a compact solution for creating reliable fiber uplinks and interconnects in data centers, campus networks and enterprise environments where short-reach multimode connectivity is required.

Advantages

The module offers simple hot-swap installation without powering down equipment, reducing maintenance windows and enabling flexible network upgrades. Its 850 nm laser and multimode fiber compatibility allow cost-effective short-range links with stable performance. The compact SFP form factor saves slot space and supports broad compatibility with devices that accept standard SFP modules, making it suitable for mixed-vendor network infrastructures.

Suitable for

• Short-reach Gigabit Ethernet connections over multimode fiber
• Optical uplinks between switches and routers in data centers
• Campus and enterprise network links requiring 1 Gbps fiber interfaces
• Media converters and SFP-capable network equipment

Key specifications

• Data rate: 1 Gbps (1000Base-SX)
• Optical wavelength: 850 nm
• Fiber type: Multimode fiber (MMF)
• Connector type: Duplex LC
• Form factor: Small Form-factor Pluggable (SFP), hot-pluggable
• Typical reach: short-range multimode links (depends on fiber type and modal bandwidth)
• Interface: SFP electrical and optical pinout compatible with standard SFP ports

How to use

Insert the SFP transceiver into a compatible SFP slot on a switch, router or media converter until it latches. Connect duplex LC multimode fiber patch cords to the transceiver’s optical ports, observing correct transmit/receive orientation. After insertion and fibre connection, verify link status through the host device’s management interface or LED indicators. To remove the module, disengage any retention mechanism and gently pull the transceiver from the slot. Follow ESD precautions and handle the optical interfaces with protective caps when not connected.

Recommendations

Use high-quality multimode fiber and matched duplex LC patch cords, and confirm fiber type and modal bandwidth are appropriate for desired reach. Keep transmitter and receiver ports free of dust by replacing protective caps when idle, and ensure devices’ SFP compatibility lists or vendor guidance are consulted to avoid interoperability issues.
