* Mains power must be interruptible with an external power supply breaker. For the power supply
breaker, observe the following recommendation:
120 Volt / 20 Amp max. or 240 Volt / 16 Amp, single-phase, 50 / 60 Hz AC service is needed, i.e.
the external AC breaker should be 20 Amps max. for 120-Volt service or 16 Amps for 240-Volt
service.
For the DC power supply, observe the local regulations of the DC service provider.
3.5. OPTICAL-FIBER-CABLE CONNECTION - RULES
Main optical system parameters:
Fiber:
Single mode fiber, type is E9/125 µm
Attenuation: <0.36 dB / km @ 1310 nm / <0.26 dB / km @ 1550 nm
Dispersion: <3.5 ps / nm km @ 1310 nm / <18.0 ps / nm km @ 1550 nm
Fibre-cable connectors E2000APC8°
ION-M system:
The specified bending radius ( < 4 cm) of the optical fibers must not be
exceeded.
The pigtails for the connection between Master Unit and Remote Unit must
have a sufficient length. A protection for the feeding into units must be given.
The system attenuation of the optical fibers, including the connectors, must
not exceed 10 dB.
System attenuation and attenuation of optical components must be determined. This
can be achieved by measuring attenuation and reflection with an appropriate
measuring instrument. For pigtails, a total value of < 0.4 dB (measured to a reference
plug) can be assumed due to the dead zone of the reflectometer. These
measurements must be made with a sufficient length of optical fiber, at the input and
output of the device which has to be measured.
Fiber-System Installation:
Fiber-cable connectors have to be of the same type (E2000APC8°) as the
connectors used for the unit. The fiber-optic cables are connected to the optical
transceiver.
Angled connectors are not compatible with straight optical connectors;
non-compatibility of connectors will result in permanent damage to
both connectors.
