The OTX-CATV-20 is RF Optic transmitter used to transmit RF signals from a RF source such as a RF headend in a Hotel, Lodge or Corporate installation over long distances or in areas where lightning is prominent.
Our CATV Optics cover all active equipment to transmit TV broadcast via a Fibre Optic Network.
• Improved Viewing Experience
• Less Maintenance
• Future Proof and Scalable Systems
• Less Power Consumption
• Logical Installation and Configuration
• Professional Product Training
• Skilled Support
Fibre Optic Benefits
• Signals are transmitted transparently by amplitude modulated light in wavelength window around 1310nm.
• The Space Stream CATV Fibre Backbone is capable of transmitting a full 1 Ghz of RF Video from the headend to the Subscriber tv set.
• Eliminates the impact static as a result of lightning strike when compared to traditional coaxial copper CATV RF networks.
• Cost Saving by way of lower maintenance over time
• Improved Signal Quality over Coax Copper networks
• Cost Effective method for distributing HDTV over large distances.
• Less Signal Attenuation over Copper networks.
• No RF interference over the Fibre network.
• Optical CATV system provides greater bandwidth capacity.
• Utilizes Single Mode Fibre Optics Backbone.
• CATV Optical Transmitter and Receivers work very linear with no distortions. The New Fibre Possibilities
• Cable Television Networks have centralized head ends where signals are received and processed and then distributed via Fibre Optic infrastructure to sub head ends.
• The Optical Transmissions used in a Hybrid Fibre Coax (HFC) networks that can be combined with active coaxial parts of the access network.
• The Centralized CATV Network processes the signal from Terrestrial or Satellite sources and then converts them to an optical output which is sent out to the network.
• The Option of Internet and Return Path Signals may be added to the Fibre Network at the main head end.
• All the Optical Cables are distributed and terminated at the Optical receiver /Optical Node. The Optical Receivers convert the Signal from Light back to RF so they can be redistributed to the home via Coaxial Cabling. Fibre Optics
| Optical transmitter 1310 nm for HFC networks
• Directly modulated and cooled high-performance DFB laser
• Automatic processor-controlled adjustment of the laser drive with regard to level and channel loading of various RF input signals produces the best transmission characteristics in terms of low intermodulation (CTB/CSO) and low noise
• Multichannel pre-distortion and GaAs amplifier technology also provide the best signal quality with low noise and low distortion
• 32-bit microprocessor for automatic monitoring and control of the laser ensures constant output level and long service life
• 19” 1 U HE enclosure with 10TBase Ethernet (IEEE802.2) and RS 232 interface for external network monitoring
• RF connectors: F female
• Fibre optic connectors: SC/APC
