Dual-Head 4K KVM Extender
The Black Box KVXLCHDPF-200 is a fiber-based KVM extender that transports dual-head 4K video, USB 2.0, audio and serial signals between a computer and a remote console. It supports resolutions up to 3840 x 2160 at 30 Hz over singlemode fiber links up to 30 km. The transmitter and receiver units each measure 1.71" H x 7.09" W x 3.27" D and weigh .85 lb without SFP modules. This kit suits operators who need to locate workstations far from secure or noise-sensitive environments.
Build Integration
The transmitter connects to a host via one HDMI and one DisplayPort input, a USB Type-B port, a DB9 serial port and analog line-level audio. The receiver provides two HDMI outputs, four USB Type-A ports for HID and mass-storage peripherals, a DB9 serial port and mic/speaker jacks. Both units require an SFP transceiver (not included) rated up to 1250 Mbps and the supplied 5 V / 2 A external power adapters. A local video loopback on the transmitter allows on-site monitoring without extra splitters.
Thermals and Power
Each unit draws power from its own 5 V / 2 A DC supply, so no internal fans or active cooling are present. The metal enclosure dissipates heat passively, resulting in silent operation suitable for control rooms or studios. LED indicators show red for power and green for link status on both ends. The fiber link eliminates electromagnetic interference and ground-loop issues common with copper cabling over long distances.

Questions about this item
How far can the 4K dual-head signal travel over singlemode fiber before it degrades?
The extender transmits dual 4K video up to 30 km over singlemode cable, and the SFP link is rated for up to 10 km at <1250 Mbps.
What are the power draw and heat indicators when the transmitter and receiver run continuously?
Each unit uses an external 5 V / 2 A DC supply; a red power LED and green link LED show normal operation with no fan noise.
Which SFP module and fiber patch cables must I already have to link the transmitter and receiver?
You need a pair of SFP transceivers rated <1250 Mbps and matching singlemode patch cords with LC connectors for the SFP cages on both units.
