Caution:
When connecting the fiber optic, pay attention to the following:
1) Do not bend the fiber optic overly.
2) Correctly connect the Tx and Rx ends of the module interface.
3) Ensure the cleanness at the interface of the fiber optic.
7.2 1000Base-ZX Module
Caution:
1) In the case that the optical interface does not connect with an optical connector or the dust-proof cap
is removed, it is possible for invisible rays to emit from this optical interface. Therefore, do not stare at
the optical interface.
2) If no optical connector is installed in the optical interface, make sure a dust-proof cap is placed on it.
3) Before connecting the optical fiber, make sure the connector matches the adopted optical fiber.
1000Base-ZX module provides one GE optical interface and uses Single Mode fiber
with a maximum transmission distance of 70km.
