Fiber Optic SFP Devices
An optional Gigabit SFP transceiver (1000BASE-SX, 1000BASE-LX, or
1000BASE-ZX) can be used for a backbone connection between switches,
or for connecting to a high-speed server.
Each single-mode fiber port requires 9/125 micron single-mode fiber
optic cable with an LC connector at both ends. 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 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 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 the LC port’s rubber plug. When not connected to a
fiber cable, the rubber plug should be replaced to protect the optics.
