1 GENERAL DESCRIPTION
1.1 OPERATING PRINCIPLE
The F2MUX is a family of converter devices intended to convert an optical interface into an
electrical interface or optical with a different protocol and/or connector.
The most significant application of the F2MUX is to communicate differential protection
equipment through a multiplexer equipment (see FIGURE 2) or another telecommunication
equipment.
The device input interface is identified as INTF1 and consists of an optical fiber interface
that can be multimode with ST female connectors (P2 of INTF1) or single mode with FC
female connectors (P1 of INTF1).
The INTF1 input interface is configurable in mode:
C37.94 with a fixed number of timeslots (1, 2 or 8) or with the number specified in the
trame itself.
CMI/FM0 at 64 kbit/s, 128 kbit/s, 512 kbit/s or 2048 kbit/s.
Transparent 1 (up to 28800 bit/s).
Transparent 2 (up to 960 kbit/s).
The device output interface is identified as INTF2 and can be one of the following:
P1 of INTF2: electrical interface at 2 Mbit/s in accordance with Recommendation G.703
of the ITU-T with codirectional clock, with connector type selectable between two
unbalanced BNC connectors (75 Ω) or a balanced RJ-45 connector (120 Ω).
P2 of INTF2: electrical interface at 64 kbit/s in accordance with Recommendation G.703
of the ITU-T with codirectional clock, with two three-pin connectors, one for transmission
and one for reception.
P3 of INTF2: optical fiber interface in accordance with C37.94 standard, with SFP (Small
Form Factor Pluggable) bay.
P4 of INTF2: multimode optical fiber interface in accordance with C37.94 standard, with
two ST female connectors, one for transmission and one for reception.

As an example, in FIGURE 1, a rear view of the equipment is shown in which the
arrangement of the different interfaces can be seen. It must be considered that the
device will leave the factory only with the INTF1 and INTF2 interfaces corresponding
to the F2MUX version.
FIGURE 1 Example of the arrangement of the different interfaces of an F2MUX device (

)
The F2MUX is supplied in a 19” shelf that is one standard unit (s.u.) in height, prepared for
rack mounting. The shelf integrates an isolated multirange power supply (36-300 Vdc,
38-265 Vac), as well as the INTF1 and INTF2 interfaces corresponding to the F2MUX
version.
F2MUX versions are detailed in section 1.2, according to the type of interface.
The F2MUX family of converter devices complies with IEC TS 61000-6-5 standard.
