Mechanical Characteristics

4.3.1.

Installation

The equipment is very easy and quick to install. It is designed for stationary use in split mount
installations. IFU and ODU are interconnected with coaxial cable. One cable for each ODU is used. (i.e.
Two cables needed for HSB, 1+1 FD and 2+0 systems). The IFU can be installed as a stand-alone unit,
or it can be mounted in a standard 19" rack (Ref. IEC 297-2 and IEC 297-3), or in an ETSI standard
cabinet (Ref. ETSI EN 300 119). The ODU
to and including 1.8 m. Alternatively the ODU can be supplied with a mount for a vertical column (Ø=60-
115mm).
