Q

What maximum distance is defined in standards documentation for 1000BASE-LX running over MMF?

A

550 m (1804 feet). Note that 1000BASE-LX can run over MMF or SMF. SMF has much higher range.

Q

You need to provision a fiber patch panel to terminate incoming cabling with green LC connectors. What type of ports should be provisioned on the patch panel?

A

Green connector color-coding indicates angled physical contact (APC) finishing. This type of finishing is incompatible with PC or UPC ports. The patch panel must be provisioned with Lucent Connector ports with APC finishing type.
