What is BS EN 50289-1-1 - Communication cables about?
BS EN 50289 is a series on communication cables. Communication cables are a type of guided transmission media.
Cables are usually known to transmit electric energy. BS EN 50289-1-1 specifies the electrical test methods for cables used in analogue and digital communication systems.
Who is BS EN 50289-1-1 - Communication cables for?
BS EN 50289-1-1 on communication cables is useful for:
- Telecommunication equipment manufacturers
- Telecommunication component manufacturers
- Design engineers
- Quality control personnel
Why should you use BS EN 50289-1-1 - Communication cables?
Communication cables in telecommunications fields are used to transmit electromagnetic waves; they are called electromagnetic waveguides.
BS EN 50289-1-1 is used for measurement of performance against standards, the differential mode terminations applied to the cable or cabling under test (CUT) will provide the differential mode and common mode reference termination impedances specified in standards for the cabling system where cable or cabling under test (CUT) is used. 50 Ω differential mode to ground terminations is used on all active pairs under test. 50 Ω differential mode to ground terminations is used on all inactive pairs and on the opposite ends of active pairs for NEXT and FEXT testing. Inactive pairs for return loss testing are terminated with 50 Ω differential mode to ground terminations. Small geometry chip resistors are used for the construction of resistor terminations. The two 50 Ω DM terminating resistors are matched to within 0,1 % at DC, and 2 % at 1 000 MHz (corresponding to a 40 dB return loss requirement at 1 000 MHz). The length of connections to impedance terminating resistors is minimized. Use of soldered connections without leads is recommended.
Using BS EN 50289-1-1 you can specify the electrical test methods for cables used in analogue and digital communication systems.
