Separating ADSL and POTS
The VESALA® YT-B splitter is designed to separate ADSL (Asymmetric Digital Subscriber Line) from POTS (telephone) when they are transmitted on a same wire pair and terminated by means of Tyco QDF-E® (Mondragon) MDF technology. The splitter protects POTS from interference caused by ADSL signals and equally protects ADSL from transients generated by, for example, POTS dialling and ringing, and from impedance fluctuations like off-hook / on-hook transitions.
Saving costs with YT-B
The ingenuity of the design of YT-B splitters is it they can be plugged into QDF-E® terminal blocks in a local exchange, one by one, as needed. Ordinary splitters require an operator to install large splitter racks and equipment awaiting possible future use. With YT-B only one terminal block is usually needed for five subscribers. All this results in considerable cost savings and allows unparalleled flexibility when ADSL/POTS usage ratio changes over time.
YT-B is easy to install to QDF-E® test and measurement slots - no tools are needed. The LP and HP filters of YT-B connect to respective pairs directly via contacts inside the terminal. Individual filters can be plugged into terminals adjacent to each other. Each YT-B requires a space of two pairs from a 10-pair terminal block. YT-B has symmetric mechanical shape, which allows best access to neighbouring terminals and their wire pairs. YT-B sticks out less than 40mm from the terminal block, which is an asset compared to bulky competitors.
Filter operation
YT-B splitter contains 4th order passive low-pass filter and 1st order high-pass filter.
More detailed information on how to use YT-B can be found in the YT-B Brochure.
YT-B is a non-stocked product. Please consult us via feedback page or email for pricing and availability.
