Adjustable optical coupler

A method, comprising:

• determining requirements for distributing a downstream optical signal to a plurality of optical terminals;
• determining a first configuration of a first optical signal distribution module based on the requirements for distributing a downstream optical to obtain a first determined configuration of the first optical signal distribution module;
• determining a second configuration of a second optical signal distribution module, differing from the first configuration and based on the requirements for distributing the downstream optical to obtain a second determined configuration of the second optical signal distribution module, wherein the first and second optical signal distribution modules are similar;
• configuring the first optical signal distribution module according to the first determined configuration to obtain a configured first optical signal distribution module;
• configuring the second optical signal distribution module according to the second determined configuration to obtain a configured second optical signal distribution module;
• and
• operating the configured first optical signal distribution module and the configured second optical signal distribution module to distribute selectable portions of the downstream optical signal to the plurality of optical terminals according to the requirement.

A configurable optical signal distribution system, comprising:

• a first configurable optical signal distribution device comprising a first upstream optical port configured to receive a downstream optical signal, a first optical tap port in optical communication with a first plurality of downstream optical terminals and a downstream optical port, wherein the first configurable optical signal distribution device is configured according to a first diversion that directs a first diverted portion of the downstream optical signal toward the first optical tap port and a non-diverted portion of the downstream optical signal toward the downstream optical port;
• and
• a second configurable optical signal distribution device comprising a second upstream optical port in communication with the downstream optical port, and a second optical tap port in communication with a second plurality of downstream optical terminals, wherein the second configurable optical signal distribution device is configured according to a second diversion that diverts a second portion of the non-diverted portion of the downstream optical signal toward the second optical tap port,
• wherein the first and second configurable optical signal distribution devices are structurally identical, and
• wherein the first and second diversions are different.
