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.
2 Fiber Input 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.
AGC-FAL : It is designed with fully aluminum body. It has SUNLAND AGC module which is very accurate in performance & sensitive with optical conversion. Very professional design is used is used for RF amplification. Specific modules can be used according to user’s requirement.
It is just use a double IC double output optical receiver. Only difference is that it operates on DC power supply instead of AC. It reduces complication of power pass system. It is very easy to maintain the co-axial cable line.
We have a lot of models with dual output, dual IC optical receiver. Class wise it is only difference with some hardware materials used with it like size of transformers; length of main chord weight of chassis, optical monitor ring system etc.
It is Field Effect Transistor node. 5 stages of field effect transistor are used in cascading mode to boast the RF signal. Very high sensitive photodiode is used for conversion. FET has very high input impedance and low output impedance.
FTTH is a special optical receiver product for FTTH network structure. The internal circuit of the special product is made of MMIC. This product is very popular in international market because of high gain and better ESO & UIB.
This type of optical receiver is specially designed to overcome the problem of power supply in the field. It is a quality optical receiver as well as 2A power source itself. It is output connectors produce RF signal along
We have a lot of models with dual output, dual IC optical receiver. Class wise it is only difference with some hardware materials used with it like size of transformers, length of main chord, weight of chassis, optical monitor ring system etc.
This optical receiver is advanced product designed for CATV. It has been parallel 4 outputs with double monitor. Available in aluminum alloy body as well as aluminum-cast water proof body. It is the best choice for CATV HFC network.
FTTH F8 Node is basically a fibre to the home node, having 8 output ports. It has very sensitive MIMIC in its circuit. It has balanced 8 outputs (RF). It is suitable for digital as well as Analog RF system.
