How to Connect to SFP Fiber Optic Ports
The switch provides four slots for SFP-compliant fiber-optic transceivers.
Note that all 1000BASE fiber optic ports operate at 1 Gbps full duplex.
Note:
The length of fiber optic cable for a single switched link should not exceed
the relevant standards specified in this section. However, power budget constraints
should also be considered when calculating the maximum fiber optic cable length
for a particular link.
Note:
Maximum distances may vary for different SFP vendors.
Connection Procedure Follow these steps to connect cables to SFP transceiver ports.
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.
Warning:
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.
1. Remove and keep the fiber port’s rubber plug. When not connected to a fiber
cable, the rubber plug should be replaced to protect the optics.
