Passive Optical Couplers Having Passive Optical Activity Indicators and Methods of Operating the Same

The method comprising:

• inserting a first connector of a first optical fiber into a first port of a passive optical coupler, the passive optical coupler further including:
• a second port configured to receive a second connector of a second optical fiber to optically couple the second optical fiber to the first optical fiber, and
• a passive optical activity indicator positioned at least partially within the passive optical coupler substantially perpendicular to an axis of the first and second optical fibers when received in the respective first and second ports and at least partially exposed, wherein the passive optical activity indicator is configured to passively illuminate in response to (i) first light propagating in the first optical fiber when the end of the first optical fiber is received in the first port, and (ii) second light propagating in the second optical fiber when the end of the second optical fiber is received in the second port;
• configuring a light source at an optical terminal to transmit light into an optical fiber;
• detecting light externally exposed by the first portion of the passive optical activity indicator;
• and
• determining whether the optical terminal is optically coupled to the passive optical coupler based on the detected light.

A bulkhead for an fiber distribution hub of a passive optical network, the bulkhead comprising:

• a plurality of optical couplers, each of the plurality of optical couplers comprising:
• a respective first port adapted to receive an end of a respective first optical fiber;
• a respective second port adapted receive an end of a respective second optical fiber;
• and
• a respective passive optical activity indicator constructed from a passive light transmissive material, wherein the passive optical activity indicator is configured to illuminate in response to (i) first light propagating in the first optical fiber when the end of the first optical fiber is received in the first port, and (ii) second light propagating in the second optical fiber when the end of the second optical fiber is received in the second port, wherein the passive optical activity indicator is (i) positioned substantially perpendicular to an axis of the first and second optical fibers when received in the respective first and second ports and (ii) extends through and beyond a surface of a housing.
