3.2 Interconnection Cable Requirements
To install the Repeater/Cross- Repeater you will need:
•
CATx Cable: Recommended cable: S/UTP (Cat5) according EIA/TIA 56A, TSB 36 or
Digital STP 17-03170. Four pairs AWG 24. connection according EIA/TIA 568A
(10BaseT). Use of cables from a higher category (Cat5e, Cat6, Cat7) is possible..
The use of unshielded CATx Cable is possible, because of
the higher electromagnetic noise/sensitivity the device class
may not be reached, the compliance with CE regulations is
not longer guaranteed.
The use of flexible Cables (Patch cable) Type AWG26/8 is possible.
Because of the higher loss of the stranded cables, the maximum distance is
reduced to app. half the value of solid cables.
•
Fiber Cable: Two strands of fiber are required for singlehead devices, four strands for
Dualhead devices.
Please note, that the allowed distance will depend on device type AND on
used fiber type.
•
Recommended cables:
Multimode type 50/125µ
allowed distance app. 400m (1,300ft)
Multimode type 62.5/125µ allowed distance app. 200m (650ft)
Singlemode type 9/125µ allowed distance app. 10km (32,750ft)
A point to point connection is required. Having one or more patch panels
in the line is possible and allowed. Not allowed is a connection from the
Fiber link interface (LC) to any other products, especially
telecommunications or network equipment.
Our experiences show, that Singlemode devices regularly work well on
Multimode Fibers where vice versa it will never do. In addition we found,
that Singlemode devices on Multimode fibers may extend the allowed
distance on Multimode fibers to twice the regular length. Anyway this
cannot be guaranteed and must be evaluated by the end-user at his own
expense.

Power Supply: Connect the supplied 5V/DC power supplies to the Plug terminal on the
rear of both local and remote units.
