Media converter KTI Networks KGC-311 — 1000 Mbit/s, 1000Base-LX / 1000Base-SX

The KTI Networks KGC-311 media converter enables conversion between 1000Base-LX/1000Base-SX fiber interfaces and 1000 Mbit/s copper Ethernet. It is designed to bridge fiber and copper segments in Gigabit networks, allowing existing switches, routers and servers to be connected over single-mode or multi-mode fiber links. The device supports standard Gigabit Ethernet signaling and offers a compact, single-function solution for extending network reach without changing endpoint equipment.

Advantages

The KGC-311 provides transparent media conversion with support for both long-wavelength (LX) and short-wavelength (SX) Gigabit fiber standards, enabling flexible deployment across single-mode and multi-mode fiber. Its operation at 1000 Mbit/s preserves full Gigabit throughput between fiber and copper links. The unit is compact and purpose-built for straightforward installation, requiring minimal configuration while maintaining compatibility with existing Ethernet devices.

Suitable for

• Extending network links between switches and routers over fiber
• Connecting servers or workstations to fiber infrastructure
• Integrating fiber segments into copper-based LANs
• Point-to-point Gigabit links where fiber distance or EMI immunity is required

Key specifications

• Data rate: 1000 Mbit/s (Gigabit Ethernet)
• Fiber interfaces: supports 1000Base-LX and 1000Base-SX optical standards
• Copper interface: 1000Base-T Ethernet RJ-45
• Media types supported: single-mode and multi-mode fiber
• Operation mode: media conversion between fiber and copper at line speed
• Form factor: compact standalone converter for desktop or rack shelf use

How to use

Install the media converter near the copper-network endpoint or in a network closet. Connect the copper Ethernet cable to the RJ-45 port and the appropriate optical transceiver or fiber connector matching the 1000Base-LX or 1000Base-SX standard to the fiber link. Power the unit and verify link/activity LEDs to confirm the connection. Ensure that fiber type (single-mode or multi-mode) and wavelength standard correspond to the remote transceiver to establish a stable Gigabit link.

Recommendations

Use suitable fiber patch cables and SFP modules (if applicable) that match 1000Base-LX for single-mode or 1000Base-SX for multi-mode installations. Verify duplex and speed settings on connected devices are set to auto-negotiate or fixed to 1 Gbps to avoid mismatch. Place the converter in a ventilated area and protect fiber connectors from dust and bending beyond manufacturer bend-radius limits to maintain signal integrity.
