14.4.2 Surge pulse CDN for symmetric datalines CDN 118
Teseq’s CDN 118 coupling-decoupling network
is designed for convenient surge testing of
telecommunications equipment to IEC / EN 61000-4-
5, which specifies a 1.2 / 50 or a 10 / 700 μs
pulse.
The CDN 118 includes the special decoupling network and coupling elements that are required for
these tests.
The CDN 118 can be easily interfaced with the EUT
and is designed as a bench top unit. It can be
used with Teseq’s NSG series or any industry standard surge generator with the appropriate
connector adapter.
