KVM extender transmitter Adder Dual Head Dual SFP ALIF2122R

Adder Dual Head Dual SFP ALIF2122R is a KVM extender transmitter designed to extend keyboard, video and mouse signals over optical links as part of Adder SFP‑based long‑reach systems. The unit supports two independent video outputs and two SFP slots for fiber transceivers, enabling remote access to dual-head video sources with low latency and preserved image fidelity. The transmitter integrates with compatible Adder receivers to provide reliable remote control from a centralized or secure location, making it suitable for environments where distance, EMI immunity and signal integrity are critical.

Advantages

The transmitter supports dual-head video, allowing two displays to be driven from a single source while maintaining sync and resolution. Dual SFP slots provide flexibility in choosing fiber type and distance by changing optical modules, enabling single‑mode or multi‑mode operation as required. Built to work within Adder’s SFP ecosystem, the device ensures compatibility with matching receivers and simplifies deployment in racks or enclosures. Low-latency performance and optical transmission reduce susceptibility to electromagnetic interference and help maintain image clarity over long distances.

Suitable for

• Data centres requiring remote console access to servers and network equipment
• Control rooms and broadcast facilities with dual-monitor operator stations
• Secure or clean environments where fiber infrastructure is preferred for isolation
• Industrial or medical sites needing reliable long-distance KVM extension

Key specifications

• Dual-head video support for two independent displays
• Two SFP slots supporting fiber optic transceivers
• Designed for use with SFP-based long-reach KVM systems
• Optical link transport for extended distances and EMI immunity
• Low-latency transmission suitable for interactive control

How to use

Install the transmitter at the source system and populate the SFP slots with appropriate fiber modules matching the chosen fiber cabling and distance. Connect the video outputs to the source computer’s graphics outputs and attach USB or PS/2 keyboard and mouse connections as required. Link the transmitter to the paired Adder receiver via the fiber connection and power both units according to site requirements. Verify link status and video presence before handing over to the remote operator; ensure firmware and SFP module types are compatible across transmitter and receiver.

Recommendations

Choose SFP transceivers rated for the intended fiber type and distance, and use managed patching and labeling for fiber links to simplify maintenance. For critical installations, verify compatibility with the specific Adder receiver model and keep firmware up to date. Ensure proper rack mounting and ventilation to maintain operating temperature ranges.
