T3/E3 SFP Connections
The T3/E3 SFP has two DIN 1.0/2.3 screw-on connectors. The SFP is supplied with two 1 m
adapter cables with a 1.0/2.3 screw-type connector on one end and a female BNC connector
on the other end.
Step 1. Connect the 1.0/2.3 end of the cables to the connectors on the T3/E3 SFP.
Step 2. Route the cables to the left or the right of the chassis. If desired, loosely bundle the
cables together using a cable tie. Do not over-tighten the cable tie.
Step 3. Connect the BNC end of the cable to the attached equipment.
Fiber Cables
Fiber-optic cables are routed in a similar fashion to Ethernet and copper wire cables (see
Figure 32). Cables are routed under or over the chassis.
Hardware required:
• fiber cable boot (optional)
• cable ties (optional)
Note: Arrange the cables such that they do not impede the insertion or
removal of other equipment mounted in the rack.
Warnings:
• Fiber cables are sensitive to bending, twisting and general over-exertion. Extreme
caution is recommended when handling fiber cable.
• In order to ensure that the minimum fiber bend radius of 1.2 in. (30 mm) is maintained
within the allowable space, an open-angled 90º boot such as TYCO 1374737-x or
equivalent is recommended. The boots must be installed and oriented during fiber
termination.
• Observe proper fiber connector handling with respect to the use of dust covers and
cleaning.
