Pomona - Electronics Preserving Data Integrity in the Telecommunications Pipeline

Our thanks to Pomona Electronics for allowing us to reprint the following article.

Rapid advancements in telecommunications technology pose increased challenges in providing customers with broad bandwidth transmissions at the speeds they expect within the local loop. With the development of new technologies such as xDSL, more data is being transmitted at faster speeds. Thus, ensuring the integrity of that data has become increasingly important. Considering that twisted pair copper, which was originally designed for only analog (voice) transmission, is still being used as the media for these faster and more voluminous data transmissions, several key issues arise.


Twisted pair is not the best medium for the volume and speed demands being experienced in the pipeline today, let alone the limitations it will place on emerging data transmission network architecture. However, the cost for complete replacement of twisted pair in the pipeline by other media such as coax or fiber isn't feasible in many installations. The true challenge becomes developing new transmission data formats that will work faster with either twisted pair or fiber. These new data formats would provide for the continued use of existing twisted pair installations, which are prevalent in commercial and residential facilities, and allow for the flexibility of future conversion to fiber. Until then, testing of twisted pair copper is still a primary concern.


Telecommunications Testing


To ensure the integrity of the data speeding across the phone line, proper installation, qualification and maintenance of the network, from the backbone to the home or business is critical. Periodic testing of the line is required to assure continued transmission accuracy. Essential tests include cable and transmission testing of the physical layer to verify its capability to transmit analog or digital signals; protocol analyzer testing to monitor the traffic on a network and to determine that it conforms to the expected protocols; and wireless communications testing of mobile/cellular base stations and mobile phones...
