Abstract:
1. An apparatus for wavelength multiplexing optical signals, the apparatus comprising: at least one dichroic splitter positioned to receive an optical signal; a filter positioned to receive the optical signal from the at least one dichroic splitter, wherein the combination of the at least one dichroic splitter and the filter provides an optical isolation of at least 75 dB; and a casing for receiving optical components of the apparatus, the casing comprising: a first casing portion, the first casing portion having at least one first signal communication aperture formed therein, at least one first optical component insertion aperture formed therein, a first substantially hollow interior portion, and at least two guide posts extending therefrom; and a second casing portion, the second casing portion having at least one second signal communication aperture formed therein, at least one second optical component insertion aperture formed therein, a second substantially hollow interior portion, and wherein the at least two guide bores formed therein, wherein at least two guide posts are configured to engage the at least two guide bores to cooperatively form a unitary casing.
