Specification of transmitter component with dual coaxial RF connectors

6.1

General

The intention of this clause is to specify adequately the physical requirements of an optical
transmitter component with an EMwL, a modulator driver IC, a TEC and dual coaxial RF input
connectors. It will enable mechanical interchangeability of components complying with this
specification both for the PCB and for any panel mounting requirement.
6.2

Pigtail interface

All optical fibres defined in IEC 60793-2-50 are applicable.
All optical connectors defined in IEC 60874-1 are applicable if a pigtail is to be terminated with
an optical connector.

Coaxial connector

The transmitter component has male type coaxial connectors as RF1 and RF2 terminals. The
connector can handle RF electrical signals and is compatible with the SMPM connector, which is
defined in Figure 2.

NOTE

If the SMPM connector is standardized in IEC, the reference will be added in a future edition.
