SERCOS-II optical fiber
FAGOR supplies the fiber optic cables for SERCOS-II communications
between the group of drives and the CNC in a ring connection and in
lengths ranging from 1 to 100 meters. The cables between drives come
with the connectors for each module. For SERCOS-II connection under 40
m, use the fiber optic cable with polymer core. Its sales models are:
SFO-  cable
Its mechanical characteristics are:
SFO-FLEX-  cable
Its mechanical characteristics are:
For SERCOS-II connection over 40 m, use the fiber optic cable with glass
core.Their sales model is:
T. H7/17 Range of SFO- cables.
The number indicates their length in meters.
SFO-1 SFO-2 SFO-3 SFO-5 SFO-7 SFO-10 SFO-12
T. H7/18 SFO- cable. Mechanical characteristics.
Flexibility
Normal. It must only be used in systems under static con-
ditions where the minimum bending radius is 30 mm.
Use only in static conditions!
Covering
PUR. Polyurethane resistant to chemical agents used in
machine-tools.
Temperature
Work: -20°C/80°C (-4°F/176°F)
Storage: -35°C/85°C (-31°F/185°F)
T. H7/19 Range of SFO-FLEX- cables.
The number indicates their length in meters.
SFO-FLEX-10 SFO-FLEX-20 SFO-FLEX-30 SFO-FLEX-40
SFO-FLEX-15 SFO-FLEX-25 SFO-FLEX-35
T. H7/20 SFO-FLEX- cable. Mechanical characteristics.
Flexibility
High. Special for cable-carrying chains with a minimum
bending radius, in dynamic conditions, is 70 mm.
Use only in dynamic conditions!
Covering
PUR. Polyurethane resistant to chemical agents used in
machine-tools.
Temperature
Work: -20°C/70°C (-4°F/158°F)
Storage: -40°C/80°C (-40°F/176°F)
INFORMATION. The maximum length for fiber optic cables of the models
mentioned earlier for best performance is 40 meters.
INFORMATION. The SFO-FLEX- fiber optic cables are compatible with
the SFO- cables. The SFO-FLEX- are more flexible.

NOTE. If the fiber optic cable for SERCOS communication between
modules is going to be moving (dynamic conditions),
always use the SFO-
FLEX-
 cable. The SFO- cable will be enough for static conditions
(resting). The useful life span of a SFO-
 cable cannot be guaranteed if it
is installed in applications where it works under dynamic conditions
(moving).
