HD-FT01-TX/RX fiber conversion for LED displays
The Huidu HD-FT01-TX/RX is an Ethernet media converter for LED control-system links. It converts electrical signals on twisted-pair network cable to optical signals for longer cable runs. The product documentation describes fiber transmission for LED display links extending beyond 100 m.

Power specification note: the PDF overview mentions 220 V power, while its technical table specifies DC 5 V, 1 A and the illustrated unit is marked 5VDC. These descriptions conflict. Confirm the supplied unit and power adapter from their labels before installation; do not apply mains voltage to a 5VDC input.
Select the optical link
Match the A/B optical units, fiber connector and distance configuration when planning the link. The 40 km, 60 km and 80 km distances are listed as custom options, separate from the 0–25 km specification. The manufacturer describes compatibility with LED control cards from multiple brands; verify the particular controller combination before choosing replacement equipment.
Understand TX and RX
TX identifies the transmitting side of a signal path, and RX identifies the receiving side. The FT01 product range uses these labels for its fiber-link equipment. Follow the unit markings and the manual’s A/B optical details when connecting the pair.
Link indicators provide checks for the fiber connection, card detection and power status. The compact modular housing is intended to simplify installation and maintenance.

Frequently Asked Questions
What do TX and RX mean in a fiber link?
TX refers to transmission and RX to reception. On the FT01 link, follow the unit markings and the manufacturer’s A/B optical configuration when connecting the equipment.
How far can the HD-FT01 transmit over fiber?
The specification lists single-mode transmission from 0–25 km, with 40 km, 60 km and 80 km available as custom options. Confirm the supplied optical configuration for the required distance.
Which connectors does the FT01 use?
The electrical side uses a standard 1000 Mbps RJ45 interface. The specification lists SC or LC as optical connector options.
Does the FT01 use 5 V or 220 V power?
The technical table lists DC 5 V, 1 A and the illustrated unit is marked 5VDC, but the overview also mentions 220 V. Check the actual unit and adapter labels before installation; never connect mains voltage to a 5VDC input.
Can I use FT01 with another brand of LED controller?
The manufacturer describes support for LED control cards from multiple brands. It does not provide a complete tested model list in the product overview, so confirm compatibility with your specific controller and link configuration.
