Coaxial Cables - GRASS VALLEY OCP400/20 Maintenance Manual

EMC performance of cables and connectors
Grass Valley products are designed to meet or exceed the requirements of the appropriate
European EMC standards. In order to achieve this performance in real installations it is
essential to use cables and connectors with good EMC characteristics.
All signal connections (including remote control connections) shall be made with screened
cables terminated in connectors having a metal shell. The cable screen shall have a large-
area contact with the metal shell.
SIGNAL/DATA PORTS
For unconnected signal/data ports on the unit, fit shielding covers. For example, fit EMI
blanking covers to SFP(+) type ports and fit 75 Ώ RF terminators to BNC type ports.

COAXIAL CABLES

Coaxial cables connections (particularly serial digital video connections) shall be made with
high-quality double-screened coaxial cables such as Belden 8281 or BBC type PSF1/2M and
Belden 1694A (for 3Gbps).
D-TYPE CONNECTORS
D-type connectors shall have metal shells making good RF contact with the cable screen.
Connectors having "dimples" which improve the contact between the plug and socket
shells, are recommended.
