4-6Fiber Optic Devices
An optional slide-in 1000BASE-SX, 1000BASE-LX, 1000BASE-LH, or
100BASE-FX SFP transceiver may be used for backbone or remote
connections, or for connecting to a high-speed ser ver.
Each single-mode fiber optic port requires 9/125 micron single-mode
fiber optic cabling with an LC connector at both en ds. Each multimode
fiber optic port requires 50/125 or 62.5/125 micron multimode fiber optic
cabling with an LC connector at both ends.
Warning: This switch uses lasers to transmit signals over fiber optic
cable. The lasers are compliant with the requirements of a
Class 1 Laser Product and are inhe rently 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 SFP 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.
Hinweis: Bei der Wahl eines Glasfasertransceivers muß für die
Beurteilung der Gesamtsicherheit beachtet werden, das die
maximale Umgebungstemperatur des Transceivers für den
Betrieb nicht niedriger ist als die für dieses Produkts. Der
Glasfasertransceiver muß auch ein überprüftes Gerät der
Laser Klasse 1 sein.
1. Remove and keep any protective port covers. 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 ter minators on fiber optic
cables will impair the quality of the light transmitted through the cable
and lead to degraded performance on the port.
