Optical transmitter TR-901 (8x SAT IF+Terr) SIGNAL PRO

SIGNAL PRO optical transmitter TR-901 R69956 is designed for distribution of television signals in SMATV and building installations, enabling conversion of satellite DVB-S/S2 signals from QUAD or QUATRO converters and terrestrial digital DVB-T2 and FM/DAB+ radio signals to single-mode optical fibre transmission. The TR-901 R69956 SIGNAL PRO transmitter supports two satellite positions, providing simultaneous optical distribution of full SAT IF bandwidth (VL, VH, HL, HH) for each of the two satellite positions and terrestrial DVB-T2/radio signals in a single optical path. The high-performance lasers with stabilised output power (8 x 5 dBm) used guarantee low distortion, minimal noise and high resistance of the transmission path to external interference.

The TR-901 SIGNAL PRO transmitter is equipped with a precise AGC circuit to ensure a constant optical level regardless of changes in input levels. Its robust construction, effective cooling and the possibility of continuous operation within a wide temperature range allow reliable operation in professional SMATV systems. The device cooperates with SIGNAL PRO brand optical receivers, enabling the construction of extensive, multi-point distribution networks with a long range with minimal attenuation and full compatibility with modern digital television systems.

The transmitter uses the Wavelength Division Multiplexing (WDM) technique, making it possible to transmit signals based on eight independent wavelengths (1330 nm, 1350 nm, 1370 nm, 1390 nm, 1510 nm, 1530 nm, 1550 nm, 1570 nm), while maintaining adequate separation. The great advantage of this solution is that it is possible to build one infrastructure (transmitter, fibre, splitters, receiver) for the transmission of the entire signal package. In competing solutions, the infrastructure usually has to be paralleled due to the need to transmit signals from 2 satellites (2 transmitters, 2 fibres, 2 splitters each, 2 receivers). The Signal PRO solution means savings due to the need for fewer active and passive elements, spacesavings in TV cabinets and savingsin installer timedue to not having to build a double passive infrastructure.

The transmitter has an optical output (output power 8x +5 dBm) terminated with SC/APC type connector, enabling distribution of the signal to 16 receiving points (optical receivers type QUATRO REC-109 R69958). The exact number of receiving points and their maximum distance from the signal source can be determined by balancing the attenuation of the optical path with the optical power budget.

Optical-copper RTV/SAT installation using the professional line of SIGNAL PRO brand equipment for 256 apartments:

• Satellite TV (2 satellite positions)
• terrestrial TV, radio
• distribution in 1 optic fibre
• division of signal into 4 optical paths

This solution can be used in large facilities where the distance between staircases is more than a few tens of metres and you want to transmit the RTV/SAT signal in a single optical fibre. Fibre optic cable provides excellent insulation against surges. This means that any surges induced in the vicinity of the antennas will stop at the optical transmitter installed immediately behind them - all other elements of the installation are 100% protected.
