Fiber Optic Transceiver LEDs in Duplex and Simplex Hardware
Fiber optic transceiver LEDs have different functionality for each of the data Directional Modes (see “Quick Reference
Tables for Modes” on page 29). Duplex hardware is designed for Bidirectional Mode, but can be configured for
Unidirectional Mode. Simplex hardware is limited to Unidirectional Mode only. When a Duplex unit in Bidirectional
Mode loses its return path, the unit drops into Data Link-lost Mode.
Note:
For instructions on setting Duplex hardware to a particular Directional Mode and information about
each of the available modes, see “Duplex Hardware Directional Mode Configuration” on page 56.
Note:
Regardless of the Directional Mode Duplex hardware is using, the left LED is yellow and the right LED
is green. Simplex LEDs are always blue.
Transceiver LEDs in Bidirectional Mode* – Duplex Only
The following information applies to the LEDs above the fiber optic transceiver on Duplex TXs, RXs, (and boards) in
Bidirectional Mode.
* When a Duplex unit in Bidirectional Mode loses its return data path, the unit drops into Data Link-lost Mode.
** Free run video is a video mode internal to the DXLink system. When free run video is indicated, video is not
displayed (nor is black video present) out the endpoint RX. This identifies a good connection with video flow between
endpoints.
Transceiver LEDs in Unidirectional Mode – Simplex (Default) or Duplex (Configurable)
The following information applies to the LEDs above the fiber optic transceiver on Simplex or Duplex TXs, RXs, (and
boards) in Unidirectional Mode.
Note:
Only one transceiver LED will operate in Unidirectional Mode, either the TX (left) or the RX (right). The
operational LED illuminates on the side of the transceiver where data enters or leaves the hardware and
indicates the individual port where the fiber optic cable should be attached during cabling (see page 51).

Fiber optic transceiver LEDs shown on TX (left) and RX (right)
Video Status LED (left):
Off – No video is present
On (solid) – HDCP video is present
Fast blink (mostly On) – unencrypted video is present
Slow blink (mostly Off) – free-run video is present**
Link Status LED (right):
On – Link status is active
Blinking - Unit in Data Link-lost Mode*
Off – Link status is not active
DXLink TX – Data Transport LEDs:
TX is: On (solid) - Available for use; not sending data
Blinking - Sending data
RX is: Off – Transceiver port is not operational
DXLink RX – Data Transport LEDs:
TX is: Off – Transceiver port is not operational
RX is: On (solid) - Available for use; not receiving data
Blinking - Receiving data
