ClearView TX1550C CATV and Satellite Optical Transmitter

Product Description

TX-1550C series is a 1550nm CATV + satellite TV directly modulated optical transmitter, which uses
a high linear cooling DFB laser. It can transmit 47 ~ 862MHz analog & digital signals of CATV and
950 ~ 2410MHz satellite TV signals on one optical fibre. It provides a complete set of high-quality,
low-cost fibre-optic trunk transmission of satellite live television (DBS) and cable television (CATV)
for fibre-to-the-building (FTTB), fibre-to-the-Home (FTTH) Solutions.

Compatible with any FTTx PON technology, it can achieve integration of CATV + satellite TV (DVB-S2) +
Internet. use together with ClearView’s CATV EDFA or WDM EDFA for long-haul and large-area FTTH
triple play transmission.

It uses a 1U 19 “standard chassis. The working parameters of the device is controlled by a
microprocessor. The LCD on the front panel provides status display and fault diagnosis. The built-in
APC and ATC control circuits ensure laser long service life and highly reliable operation. Two
polarized RCM Certified power supply options for one satellite, which guarantees high-quality
transmission of CATV, Analogue TV, Digital TV (DBS-C, DBS-T) and Satellite TV signalsover optical fibre.

 Product Features

◆ High linear cooling DFB laser suitable for Analog TV & SAT-IF applications.
◆ Wide bandwidth: 47 ~ 862 & 950 ~ 2410MHz working bandwidth, one fibre can transmit CATV &
SAT-IF signal at the same time.
◆ Transmit 1 to 2 satellite signals.
◆ The optical transmitter can provide the same satellite with two polarized power supply options either
with + 13VDC or + 18VDC.

◆ Intuitive: The laser is the most expensive components of the device. The built-in microprocessor in
the machine monitors the external modulator and laser’s working status, and the working
parameters are displayed on the panel LCD.

◆ Standard Configuration output level 10dBm, Options 5, 7, 9dBm. Delivery 35 days from order
