CATV PRODUCTS

Cable television is a system of delivering television programming to paying subscribers via radio frequency (RF) signals transmitted through coaxial cables or, in the 2010s, light pulses through fiber-optic cables. This contrasts with broadcast television, in which the television signal is transmitted over the air by radio waves and received by a television antenna attached to the television. FM radio programming, high-speed Internet, telephone services, and similar non-television services may also be provided through these cables. Analog television was standard in the 20th century, but since the 2000s, cable systems have been upgraded to digital cable operation. OPTRONIX offers a wide range of CATV Products includes Amplifier, Node, Transmitter, EDFA, Trans-receiver, Modulator etc.

Low Pass Filter

High Pass & Low Pass Filter

  • Low pass filter suppression of high frequency is -50db.
  • High pass filter suppression of low frequency is -50db.
  • Over loss is 2db

  • Optical Receiver(Node)

    Optical Receiver(Node)

    Two fiber input node can be used for two separate optical input device for backup based on plenty of experiences about CATV HFC network ooptical fiber transmission equipment, we developed DI-155 and DI-165A series field receiver, two input optical receiver. It is mainly used in long-distance optical fiber transmission of TV image signal,digital TV signal.


    Optical Switch

    Optical Switch

    Optical Switch with GSM has an extremely low noise, low in-sertion loss. It also adopt MCU intelligent control technology and SMNP network management to make the performance better than others. The major problem comes in CATV that we don’t able to know whether our line is cut or okay. So to resolve this prob-lem we add GSM Module in Optical Switch.

    Power pass system

    Power pass system

    Cable TV system is directly link with public. It is necessary to reach the RF signal 24 hours consumer end. Therefore , it is necessary to keep our whole system (control-room, amplifiers, node etc.) to provide initial power supply every time through same co-axial cable wire to operate active power devices is called Power Pass System.

    Power Supply

    Power Supply

    This type of power supply is very useful to keep our active device on. It produces noise free and constant regulated the power even input voltage varies to a large extent.



    Transmitter

    Transmitter

    This laser transmitter is important equipment to built CATV HFC network. It is mainly used for long distance optical fiber transmission of television signal, digital TV signal telephone voice signal and data. High performance DFB laser , we select famous brand from the international market for our products as light source.


    Transreciever

    Transreciever

    Trans-receiver is simply a combination of both optical transmitter and optical receiver. It can achieve RF output of desired level of optical signal (+2 ~ -8dBm). Same time we can get optical power of desired level (9 dBm or 10 dBm). It uses two adaptors, one as a optical in and one as a optical out. Aluminum alloy body is used in outdoors trans-receivers.
