(2) Product Overview
2.1 Introduction
The FT-CWDM Series products comprise of single-mode fiber optic transmitters and
receivers for the optical transmission up to 8+1 wavelenghts into one fiber. The products work at
wavelengths from 1470nm to 1610nm with a 9/125um fiber for single-mode transmission with
FT-CWDM.
Coarse Wavelength Division Multiplexer/De-Multiplexer (FT-CWDM) Matrix Module support
optical transmission of up to 8+1 fiber channels through one single-mode fiber. It is capable to
connect up to eight units of FT fiber transmission products (each with different laser wavelength)
to maximum the video, data, audio and contact closure transmission in single fiber.
A non-compressed 10-bit digital video transmission scheme is implemented which supports
video in NTSC, PAL and SECAM formats. Transparent data transmission is also accomplished in
RS232, RS422 and RS485 formats regardless of the type of communication protocol
implemented within the system. Time Division Multiplex (TDM) technology is employed for digital
transmission of forward video and data; whereas optical Wavelength Division Multiplex (WDM)
technology is employed for simultaneous reverse data transmission as well as bi-directional data
transmission by using 2 wavelenghts.
For single-mode transmission, we also offer specifically designed products for long-haul
transmissions up to 60km. These models include the letter
“L” in the suffix, e.g. FT2410DR-SSTL
for Tx, FT2410DR-SSRL for Rx, etc.
The FT-CWDM system is the combination of plug-in FT card modules installed in a
19”
rack-mount chassis.
