Specifications for FlexBus 1500 Cable

The FlexBus 1500 is a category 5 STP cable used to connect stacked EH1500+ or compatible hubs. It supports segment configuration setup and management functions for EH1500+ or compatible hubs. Its specifications are listed below:

Cable performance level

conductor

insulation shield jacket

operating frequency impedance attenuation

high-performance data grade 8-wire, 4-pair,

24 AWG stranded bare copper polyolefin

overall aluminum foil

PVC

100 MHz Max

102 ± 15% Ohms

5.5 dB/1,000 ft

Plug 8-wire shielded modular plug for stranded twisted-pair cable

No special tools are required to install the FlexBus 1500 cable. These cables are terminated on the plugs in advance.

Tables A-1 and A-2 list the attenuation and near-end crosstalk (NEXT) loss v.s. reference frequency. Attenuation is derived from swept frequency signal level measurements at the output of 305m (1000 ft) of cable. The maximum attenuation for any pair shall be less than the values given in Table A-1 for the frequency range of 0.772 MHz to the highest referenced frequency.

Near-end crosstalk (NEXT) is derived from swept frequency measurements using a network analyzer or an s-parameter test set. A balanced signal is applied to a pair that causes disturbance while the crosstalk signal is measured at the output port of the pair being disturbed at the near end of the cable.
