Fiber Optic Transmitter
Single Channel Baseband FM

The TRANSPORT 1101-X-X-VDA2 fiber optic transmitter (Tx) provides capacity for one full motion video, multiple audio and a high speed data carrier on one fiber strand with baseband audio and video inputs.

The TR1101-VDA2 fiber optic transmitter supports broadcast quality full motion video performance over a 13 dB optical path loss (operating at 1310 nm). Each TR1101-VDA2 fiber optic transmitter features an internal FM modulator which converts direct baseband video and audio inputs to IF carriers. The IF is converted to light for transport over single mode fiber at (1310nm) to a TR1101 Receiver (Rx) for distribution.

An Auxiliary RF port also accepts a "T" channel carrier from the appropriate external RF modem for transmission of fax signals, control data or high speed 10 Mbps data. The RF input is internally combined with the FM video/audio carrier and fed to a laser diode for simultaneous transmission on a dedicated single mode fiber.

Mounting Options
The TR1101-VDA2 is available in a rack (H-T-VDA2) style and a wall (N-T-VDA2) style. See operation parameters for dimensions.

The TR1101-UR Universal Rack is a 5u high 19" housing that accommodates a power supply module and up to (10) TR1101 "H" style fiber optic transmitters and receivers.

TR1101-N-T-VDA type fiber optic transmitters are rugged stand-alone units typically located at the customer premise. The 3" x 5" x 10" package can be shelf, wall or desk mounted and includes a power transformer eliminating the need for equipment racks at all locations.
