Making Network Connections

The 1000BASE-SX/LX/LH and 1000BASE-BX10-U fiber optic ports operate at
1 Gbps full duplex. The maximum length for fiber optic cable operating at Gigabit
speeds will depend on the fiber type as listed under “1000 Mbps Gigabit Ethernet
Cable Lengths” on page 4-6. Also, remember to consider power budget constraints
when calculating the maximum cable length for each specific connection.
10 Gbps Fiber Optic Connections
An optional 10 Gigabit transceiver (XFP) can be used for a backbone connection
between switches, normally uplinked to the service provider through a single
transceiver or with two transceivers trunked together.
Single-mode fiber ports require 9/125 micron single-mode fiber optic cable. Each
fiber optic cable must have an LC connector attached at both ends.
Each 1000BASE-LR/ER single-mode fiber port requires 9/125 micron single-mode
fiber optic cable. Each 1000BASE-SR multimode fiber optic port requires 50/125 or
62.5/125 micron multimode fiber optic cabling. 1000BASE-SR/LR/ER uses duplex
fiber, operating at the same wavelength for both transmit and receive signals
(SR: 850 nm, LR: 1310 nm, ER: 1550 nm).
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.
Note: 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
only be attached in the correct orientation.
