Can a BS5308 part 1 type 1, 2 pair individually screened cable be used for M-Bus communications?

Issue

Can a BS5308 part 1 type 1, 2 pair individually screened cable be used for M-Bus communications?

Environment

M-Bus

Communication

Cables

Cause

A BS5308 part 1 type 1 cable was installed for Modbus communications, but it was then found that the communications were M-Bus

Resolution

The correct cable to use for M-Bus is J-Y(ST)Y.  These indoor telephone cables transmit analogue or digital signals; Aluminium-laminated plastic foil static screen with tin-plated drain wire minimises the interference of high frequency, electromagnetic field;TP structure minimises crosstalk.

The BS5308 part 1 type 1 cable can be used, and the chart below shows the calculations used to establish this. For the cable datasheet, please click HERE.
