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-LX GL module provides one Gigabit optical interface and uses Single
Mode optical fiber with a maximum transmission distance of 40km.
