Coaxial cable or coax is a type of cable that has an inner conductor surrounded by a tubular insulating layer, surrounded by a tubular conducting shield. Many coaxial cables also have an insulating outer sheath or jacket. The term coaxial comes from the inner conductor and the outer shield sharing a geometric axis. Coaxial cable differs from other shielded cable used for carrying lower-frequency signals, such as audio signals, in that the dimensions of the cable are controlled to give a precise, constant conductor spacing, which is needed for it to function efficiently as a radio frequency transmission line.

  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.

The type of transmitter can used for retransmit of optical signal. It can also be used as a same 1310 RF optical transmitter.

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.

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).

The age of high-speed data communications and multimedia application have dawned on cable television. It has brought with it a myriad of services such as high-speed data, video on demand, IP telephony, status monitoring, impulse pay-per-view and internet access to name a few. A cable plant must be two-way ready to carry this high-speed data traffic from a variety of sources.

Advanced phase locked loop oscillating technology and surface acoustic intermediate frequency modulation technology are used in our professional series modulator. Automatic control systems are used to monitor working status. Working status will displayed on LCD of front panels.

We are leading supplier of huge range of high pass low pass filter.

With the flexible modular design, stc-1180 can: receive and process digital programs from up to 12 dvb-css2 channels. Supports program decryption via four multi-channel cam modules with commonly adopted cas in the market.

STC-1260T offers service providers a cost-effective and scalable solution to repurpose their content from different sources and format to add digital content to their distribution network.

Stc-1330 ipqam modulator supports tv program inputs from asi and ip streams, then re-multiplexed and provides an output scrambled transport stream with up to 24 channels of qam or in 12 channels ofdm.....

Nds3542 encoder & modulator is a device integrated with mpeg2 encoding and dvb-t modulation to convert sd av signals to dvb-t rf out in the frequency range of 30~960mhz.

CATV system is basically a RF Signal distribution system. During distribution RF signal losses according to the resistance of co-axial or the length of co-axial cable it is very necessary to measure the strength of RF Signal for smooth transmission.

Highly accurate unit offering io calibrated wavelength(830nm, 850nm, 980nm, 1300nm, 1310nm, 1450nm, 1490nm, 1550nm, 1590nm and 1625nm).

It is necessary to measure the strength of optical power, before inserting the optical receiver. Optical receiver use optical power in their input is generally +2 to -8 dbm for its proper functioning our mini-power meter measure the strength of power between +4 to -15dbm accurately. Hence it is very economical and useful device for cable operators.

Based on field knowledge and 20 years of OTDR expertise, EXFO’s OTDRs are designed to meet network operators’ latest requirements. Combining intelligence and accuracy with user-friendliness, our solutions require minimal training and provide you with measurements you can trust, minimizing truck rolls and accelerating workflow in the field.

When talking on the phone or using the internet, our splicers are used to connect optical fibers with superior precision to ensure your data are transmitted reliably anywhere.

It uses the pon network structure, flexible networking and long-distance transmission of voice, data and digital video services.
