25G – for office and data centre

25GBase-T solution from Datwyler

Datwyler recently developed CU 7725 4P data cables, which can transmit up to 25 gigabits per second and provide an extended frequency range up to 1300 Megahertz (MHz).

By comparison with Category 8 cables such as Datwyler’s CU 8203 4P the new data cables have a larger conductor cross-section (AWG22), which means that they are ideally suited for the simultaneous transmission of electrical power up to 100 watts (PoE, PoE+ and 4PPoE).

Users who install these high-end data cables together with the KS-T8 RJ45 module benefit from a combination which forms an especially future-proof solution – up to 30 metres (Channel) in the data centre and in the office environment as well.

Depending on the fire performance requirement, the CU 7725 4P cables come in three versions – from Euroclass Dca to B2ca. The braid-shielded PiMF cables give a coupling attenuation (near end unbalance attenuation plus shielding attenuation) of 85 dB, thus achieving the best segregation class d.

Update of 2021:

The technical report ISO/IEC TR 11801-9905 describes this link as “Class I”, with a maximum of 30 metres (Channel) and a frequency range of up to 1250 MHz.

As there are no active components for 25GBASE-T available on the market Datwyler recommends its customers to install a 10GBASE-T cabling solution.
