Eight-Channel Video FT85081 Transmitter and FR85081 Receiver
with Bidirectional Data Channel
Features of the FT85081/FR85081 fiber optic transmission system include the following:
• 8-bit digitally encoded video for high-quality multi-channel video transmission over a
single fiber
• Bidirectional data channel that supports RS-232, RS-422, RS-485 (2-wire/4-wire),
Manchester, and Bi-Phase communication
•Wavelength division multiplexing (WDM), allowing video and data channels to be
transmitted in the same fiber using different wavelengths
• Multimode fiber support for distances up to 1 km (0.6 mi)
• Single-mode fiber support for distances up to 30 km (18.6 mi)
• Exceeds all requirements for the RS-250C Medium-Haul Transmission specification
• Compatible with NTSC, PAL, and SECAM video standards
• No performance adjustments required
• 12 VDC or 24 VAC power supply
• Standalone and rack-mountable modular design
• LED indicators for monitoring of signal status, data activity, and operating power
NOTE:
The FT85081 transmitter/FR85081 receiver is a Class 1 laser product that
complies with FDA radiation performance standard 21CFR Subchapter J and with
IEC 60825-1 Edition 1.2, 2001-08.
