Spacing cable straps
Tighten the 7K-1181 Cable Straps using the 326-8203 Tool, at the end furthest away from the chosen figure-8 loop section. Space the cable straps at 8-16 inch intervals. Refer to Illustration 48.
Illustration 49 g06350869
Bundling
(1) Center
(2) Each end
If extra length is present, bundle the length into a figure-8 loop and loosely secure the loop using 3 Cable straps using the 326-8203 Tool. Secure one cable strap to center of figure-8 loop and the two remaining on each end of loop. Refer to Illustration 49.
Illustration 50 g06350871
Measuring bend radius
Use a ruler to ensure that the correct bend radius requirement is being maintained. Refer to Illustration 50. In this example, the figure-8 has a bend radius greater than minimum specification and is acceptable to use.
Illustration 51 g06350886
Adjusting the bend
Ensure to make the necessary adjustments to meet the bend requirement and then tighten the cable straps using the 326-8203 Tool. Refer to Illustration 51.Modifying a 4 Wire Ethernet Patch Cable
Modification is allowed only on a 4 wire Ethernet patch cable. Some 4 wire Ethernet patch cables may need modified by removing a BR series contact and installing Deutsch contacts on 1 or both ends. Perform the following procedure to modify a 4 wire Ethernet patch cable:
Illustration 52 g06350897
4 wire Ethernet patch cable to modify
Identify the 4 wire Ethernet patch cable that needs to be modified. Refer to Illustration 52.
Illustration 53 g06350898
Removing contacts
Cut off the contacts. Refer to Illustration 53.Note: The end length of the twisted pair must be even. Cut both wires at once to ensure this length.
Illustration 54 g06350899
Unshielding wires
Strip or unshield all wires evenly to accommodate Deutsch contact pin. Refer to Illustration 54.
Crimp Deutsch contact onto wire.Note: After crimping, retwist the wire.
Illustration 55 g06350900
Inspecting wires
Perform an inspection on the total end length of the wires. Both wires should be within 1mm of each other. Refer to Illustration 55.
Illustration 56 g06350903
Inserting contacts into connector
While maintaining full twist to the connector, push contacts into connector. Refer to Illustration 56.
Illustration 57 g06350904
Measuring untwisted/unjacketed area
Perform an inspection on the untwisted/unjacketed area of the Ethernet cable. The untwisted/unjacketed area should not exceed 45 mm (1.77 inch).Reference Section
Tx - Data transmitRx - Data receiveLAN - Local Area NetworkWAN - Wide Area NetworkCapacitance - This term is the ability for an object to store electrical energy. Some objects are designed to store electrical energy other objects have the natural ability to store energy.Insertion Loss (Attenuation) - Insertion loss is the loss of power in a signal when insertion of outside force occurs (for example voltage resistance, reflections, length of cable, or crosstalk).Return Loss - This term is the loss of power in the signal, reflected (returned) on a single copper plane (for example reflection on a contact). The loss is typically expressed in dB.Velocity of Propagation - This term is the speed of a signal through the full length of the cable.Dielectric - This term is a substance that transmits electric force without conduction, an insulator.EMI (Electromagnetic Interference) - This term is an external force that generates an electromagnet field that interferes
