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 ~ 2600MHz 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.

◆ High linear cooling DFB laser suitable for Analog TV & SAT-IF applications.
◆ Wide bandwidth: 47 ~ 862 & 950 ~ 2600MHz working bandwidth, one fiber can transmit CATV & SAT-IF signal at the same time.
◆ Transmit 1 ~ 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.

◆ It can be used with CATV EDFA or WDM EDFA for long-haul and large-area transmission of FTTH triple play integration.

◆ Can be integrated and compatible with any FTTx PON triple play.
