Laying out the Optical Fiber Jumper
11.1 Laying out the Internal Optical Fiber Jumper Tips Select the optical fiber jumpers according to the types of the optical interfaces on the equipment at both local and far end. All optical interfaces on the CiTRANS 650 U3 side are the LC/PC type. The optical fibers on the ODF side usually use the FC/PC type or SC/PC type interface according to the type of the ODF side optical interface.
LC/PC type fiber connector
FC/PC type fiber connector
SC/PC type fiber connector
Note The LC/PC-LC/PC fiber connector is used to connect optical interfaces inside the cabinet. The LC/PC-FC/PC fiber connector and LC/PC-SC/PC fiber connector are used to connect the equipment and the optical interface of t he ODF.
11.1.1 Preparation Before Layout Tips Installers should prepare the following items before the layout. Make and attach temporary labels on both sides of the optical fiber to be arranged. Arrange the optical fiber in order and lay them straight. Please note that the fiber should be arranged in pairs for transmitting and receiving. Cut out an appropriate length of corrugated conduit according to the length of optical fiber (the fiber between the cabinet on the local end and the cabinet / ODF on the far end should be protected by the corrugated conduit). Adjust the length of optical fiber outside the corrugated conduit: If there is a redundant length of the fibers at the client side and line side, installers should reserve the redundant parts of the fibers at the ODF side, so as to ensure that the fibers access the cabinet from the client and line sides without redundancy. Route the optical fiber with the corrugated conduit from other cabinet or ODF to the cabinet via the upper support channel, and lead the fiber into the cabinet via the wiring hole.
13
11.1.2 Layout Procedures Caution Connect the optical fiber to the corresponding optical interface on the card.
Exercise care if you must bend fibers. If bends are necessary, 1 the fiber bending radius should never be less than 40mm.
2 Lead the optical fiber through the fiber guide unit of the subrack and route it along the wiring channel on the cabinet to the fiber passage area of the subrack (The top access wiring mode is taken as an example for introduction). Top access wiring mode: Lead the optical fiber into the cabinet through the cabinet-top wiring holes and route the fiber downward. Floor access wiring mode: Lead the optical fiber into t he cabinet through the cabinet-bottom wiring holes and route the fiber upward.

Caution Installers should bind all wires and cables used in onsite installation. Each cable type should be bound separately. For example, power cables, alarm cables and optical fibers should be laid out independently and bound separately. Note that optical fibers should be bound with dedicated cable ties.
14
11.2 Arranging the Optical Fiber Jumper After completing the connection of the optical fibers, installers should bind the optical fibers at the entrance of the cabinet and at the point near to the fiber passage area with cable ties to secure them. Connect the optical fiber at the ODF side. Make and attach labels to both ends of the optical fiber. Tips The interval of binding cables should be t hree or four times the diameter of the cable bundles, and make sure that intervals are equal.
