1. An alignment system comprising:
an alignment source module configured to releasably couple to a first unit of a pair of optoelectronic arrays such that the alignment source module is oriented to emit an optical beam in substantial alignment with a first optical axis of the first unit; and,
an alignment indicator module configured to releasably couple to a second unit of the pair of optoelectronic arrays such that the alignment indicator module provides a visible indication when the optical beam is within a predetermined near-alignment orientation range relative to a second optical axis of the second unit,
wherein:
the predetermined near-alignment orientation range comprises angles outside of a precision alignment range defined by the pair of optoelectronic arrays,
each of the alignment source module and the alignment indicator module is configured to axially couple along a longitudinal axis of the respective unit of the pair of optoelectronic arrays, the longitudinal axis being substantially parallel with an array of optical elements of the respective unit, and,
the alignment source module is configured to be in pluggable electrical connection with the first unit and physically removable from the first unit prior to a precision alignment.
