Adder XD150FX-MM-US – Multimode Fiber DVI KVM Extender Pair

Product Overview

The Adder XD150FX-MM-US AdderLink XD150FX is a multimode fiber KVM extender pair that carries dual-link DVI video, transparent USB 2.0, and bidirectional audio over a single duplex LC fiber cable, with US mains leads included. Built as a multimode fiber DVI KVM extender for in-building runs, it supports resolutions up to 2560x1600 @ 60Hz at distances from 150m on OM2 fiber to 400m on OM4. Facilities use it to relocate computers into a secure, climate-controlled room while operators keep a visually lossless, real-time desktop with full USB peripheral support.

Product Description

The XD150FX ships as a complete transmitter and receiver pair fitted with SFP cages; this MM version includes multimode 4G optics. Over standard multimode plant the rated distances are 70m on OM1, 150m on OM2, 380m on OM3, and 400m (1,312ft) on OM4 — ideal ranges for riser and campus-building links where multimode fiber is already installed.

Video extension is visually lossless with no visible artifacts or latency. Dual-link DVI resolutions to 2560x1600 @ 60Hz are supported, with intelligent EDID management passing the true characteristics of the remote monitor back to the source computer for correct output every time. Because the link is optical, it is immune to electrical interference and provides galvanic isolation — a real benefit in industrial plants and electrically noisy technical spaces.

USB 2.0 support is transparent across low, full, and high speeds and — unusually for a KVM extender — includes isochronous devices, so webcams and USB headsets work at the remote desk through the receiver's built-in 4-port hub. Bidirectional CD-quality analog audio (24-bit/96kHz) covers line in/out, microphone, and headphones, while RS232 passes between units at up to 115,200 baud with RTS/CTS flow control.

Each unit offers a web interface with HTTP digest authentication for status and temperature monitoring, plus a REST API for integration with third-party control systems. The fanless pair is plug and play, delivered zero-config with no drivers required. Need longer reach? The single-mode XD150FX-SM-US extends to 4km.

Key Features

• Multimode Fiber Extension to 400m — Rated distances of 70m (OM1), 150m (OM2), 380m (OM3), and 400m (OM4) with the included multimode 4G SFPs.
• Dual-Link DVI to 2560x1600 — Visually lossless video at up to 2560x1600 @ 60Hz with no visible artifacts or latency.
• Single Duplex LC Cable — Video, USB 2.0, and audio all travel on one fiber link, simplifying cable plant and patching.
• Isochronous USB 2.0 Support — Webcams, headsets, touch screens, and mass storage all operate through the receiver's 4-port hub.
• CD-Quality Bidirectional Audio — 24-bit/96kHz stereo with microphone and headphone support at the user position.
• Web Interface and REST API — Status and temperature monitoring with individual function control and third-party control system integration.
• RS232 with Flow Control — Serial passes between units at up to 115,200 baud via the options port.
• Plug and Play, Fanless — Zero-config delivery, silent operation, 400,000-hour MTBF in compact metal enclosures.

Typical Applications

• Broadcast studio — edit and graphics machines racked in the apparatus room with operators connected over building fiber.
• Auditorium — presentation and show-control computers extended from a remote rack room over existing multimode plant.
• House of worship — production PCs kept in a media room while the operator position runs over fiber.
• Government space — electrically isolated optical links between equipment areas and user desks.
• Multi-purpose room — centralized source PCs with full KVM control extended to flexible room layouts.

Frequently Asked Questions

What distance can I achieve on my existing fiber?
Rated distances depend on the multimode grade: 70m on OM1, 150m on OM2, 380m on OM3, and 400m on OM4, all with duplex LC connectors. For runs beyond 400m, choose the single-mode XD150FX-SM-US rated to 4km.

Is this a complete kit?
Yes. XD150FX-MM-US includes both transmitter and receiver units with two power adapters and US mains leads.

Do webcams and USB headsets work at the remote desk?
Yes. Isochronous USB devices are supported, which most KVM extenders cannot offer, so conferencing peripherals operate normally at the user position.

Will it work with my operating system?
All known operating systems are supported. The extender is transparent to the host and requires no drivers or software.

Can it tie into a room control system?
Yes. The REST API exposes all functionality to authorized third-party control systems, and the web interface provides monitoring and per-function control.

What mounting options exist?
Optional kits include the RMK8 19-inch rack mount (two units per 1U), RMK10 wall/desk mount, and RMK5V VESA mount for attaching a unit behind a display.
