HORIZONTAL CABLING DESCRIPTION A.
Horizontal cable and its connecting hardware provide the means of transporting signals between the telecommunications outlet/connector and the horizontal cross-connect located in the communications equipment room. This cabling and its connecting hardware are called "permanent link," a term that is used in the testing protocols.
B.
Horizontal cabling shall contain no more that one transition point or consolidation point between the horizontal cross-connect and the telecommunications outlet/connector.
C.
Bridged taps and splices shall not be installed in the horizontal cabling.
D.
Splitters shall not be installed as part of the optical fiber cabling.
E.
The maximum allowable horizontal cable length is 295 feet (90 in). This maximum allowable length does not include an allowance for the length of 16 feet (4.9 m) to the workstation equipment. The maximum allowable length does not include an allowance for the length of 16 feet (4.9 m) in the horizontal cross-connect.
