T-Series DVI Modules, Rev. G 8 October, 2016
2.3 Module LEDs
Both the Transmitter and Receiver Modules feature five LEDs. Their functions are as follows:
2.4 Fiber Optic Cable
Fiber optic cables connect the Transmitters to the Receivers. Standard multi-mode fiber optic cables
must be 50 or 62.5 microns, terminated with LC type fiber optic connectors.
Be careful not to kink or
pinch the fiber optic cable as it is being installed and keep all bend diameters to no less than 3
inches (76.2mm).
Standard multi-mode fiber optic cable (up to 1000 meters),
50 or 62.5 microns, terminated with LC-type connectors
◄Transmit ◄Receive
With two fibers connected (in models with one SFP) or with three fibers connected (in models with two
SFPs) video information is transmitted from the TX to the RX over fiber L1 (and L3 in models with two
SFPs). Fiber L2 is used as a data return path from the RX to the TX, allowing full duplex, bi-directional
RS-232 data transfer.
2.5 Installation
All physical connections to the product use industry-standard connectors. Non-supplied cables are
commercially available. All connections are found on the rear of the unit.
