FWT-2600C Series CATV+IF Satellite Optical Transmitter
1. Product Description FWT-2600C 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 960 ~ 2410MHz satellite TV signals on one optical fiber.
FWT-2600C series 1550nm satellite + CATV optical transmitter, which provides a complete set of high-quality, low-cost fiber-optic trunk transmission of satellite live television (DBS) and cable television (CATV) for fiber-to-the-building (FTTB), fiber-to-the-fiber Home (FTTH) Solutions.
Compatible with any FTTx PON technology, it can achieve integration of CATV + satellite TV (DVB-S) + Internet. use together with Fullwell's CATV EDFA or WDM EDFA for long-haul and large-area FTTH triple play transmission.
FWT-2600C series 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 the long service life and highly reliable operation. Two polarized power supply options for one satellite, which guarantees high-quality transmission of CATV, Analog TV, Digital TV (DBS-C, DBS-T) and Satellite TV signals over optical fiber.
2. Product Feature
2.1 High linear cooling DFB laser suitable for Analog TV & SAT-IF applications.
2.2 Wide bandwidth: 47 ~ 862 & 950 ~ 2410MHz working bandwidth, one fiber can transmit CATV & SAT-IF signal at the same time.
2.3 Transmit 1 ~ 2 satellite signals.
2.4 The optical transmitter can provide the same satellite with two polarized power supply options either with + 13VDC or + 18VDC.
2.5 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.
2.6 It can be used with CATV EDFA or WDM EDFA for long-haul and large-area transmission of FTTH triple play integration.
2.7 Can be integrated and compatible with any FTTx PON triple play.
