KTI Networks SFP-GLM-A Gigabit SX SFP Transceiver, 1.25Gbps, 850nm, Multimode, LC, 550m

Network upgrades often stall when a switch lacks the right optical interface for multimode fiber runs. The KTI Networks SFP-GLM-A closes that gap: a hot-swappable SFP module that delivers 1000BASE-SX Gigabit Ethernet over existing multimode cabling, so you can extend links up to 550 meters without replacing switches or pulling new fiber.

Who is it for

IT technicians and network administrators who need to add fiber connectivity to KTI switches like the KS-1080 or KS-2000 series, or to any SFP port that accepts MSA-compliant modules. It fits commercial environments where multimode fiber is already installed and a reliable, low-power link is required.

Main features

• Standard SFP form factor for broad compatibility with Gigabit Ethernet switches and media converters.
• 1000BASE-SX transceiver operating at 850 nm over multimode fiber (OM2/OM3).
• LC duplex connector for simple, secure fiber termination.
• Supports link distances up to 550 meters on OM2 or better multimode fiber.
• Hot-swappable design allows insertion and removal without powering down the host device.
• Digital Diagnostic Monitoring (DDM) provides real-time monitoring of transceiver parameters.
• Low power consumption, typically under 1 watt, with 3.3V supply voltage.
• Full-duplex operation with a VCSEL laser source for reliable short-reach transmission.

Tips

For best performance, use OM3 or OM4 multimode fiber to achieve the full 550-meter reach. Ensure the host switch port is configured for auto-negotiation or forced to 1000 Mbps full-duplex. Always use proper ESD protection when handling the module.
