CHAPTER 4 Making Network Connections

10 Gbps Fiber Optic Connections

10GBPS FIBER OPTIC CONNECTIONS

An optional 10 Gigabit transceiver (SFP+) can be used for a backbone connection between switches.

Single-mode fiber ports require 9/125 micron single-mode fiber optic cable. Multimode fiber optic ports require 50/125 or 62.5/125 micron multimode fiber optic cable. Each fiber optic cable must have an LC connector attached at both ends.

WARNING: These switches use lasers to transmit signals over fiber

optic cable. The lasers are compliant with the requirements of a Class 1 Laser Product and are inherently eye safe in normal operation. However, you should never look directly at a transmit port when it is powered on.

WARNING: When selecting a fiber device, considering safety, please make sure that it can function at a temperature that is not less than the recommended maximum operational temperature of the product. You must also use an approved Laser Class 1 SFP transceiver.

1.Remove and keep the port’s protective cover. When not connected to a fiber cable, the cover should be replaced to protect the optics.

2.Check that the fiber terminators are clean. You can clean the cable plugs by wiping them gently with a clean tissue or cotton ball moistened with a little ethanol. Dirty fiber terminators on fiber cables will impair the quality of the light transmitted through the cable and lead to degraded performance on the port.

3.Connect one end of the cable to the LC port on the switch and the other end to the LC port on the other device. Since LC connectors are keyed, the cable can be attached in only one orientation.
