(2) Product Overview
2.1 Introduction
The FT220DB Series products comprise of either single-mode or multi-mode fiber optic
transmitters and receivers for the optical transmission of TWO forward (Tx → Rx) video and TWO
bi-
directional (Tx ↔ Rx) data signal on one fiber. The products work at wavelengths of 1310nm
and 1550nm with either a 9/125um or 62.5/125um fiber for single-mode or multi-mode
transmission respectively.
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.
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. FT220DB-SSTL
for Tx, FT220DB-SSRL for Rx, etc.
The FT220DB Series units are available as standalone units, which can be mounted
horizontally or vertically wall-mounted on any fixture. The standalone unit comes with an external
power supply FT-PA/12V, which can be powered by local 110/220V power.
The FT220DB Series units are also available as plug-in card modules installed in a
19”
rack-mount chassis. Each plug-in card occupies two slot in the rack-mount chassis. The rack
mount chassis has to be ordered separately, and comes with its own power supply for powering
the installed card modules.
