The passive component product group includes SM and PM couplers (split light at specified ratios), polarization beam combiners/splitters (combine or separate light of orthogonal polarization states), Faraday rotator mirrors (reflected light is rotated by 90° to combat system polarization effects), polarizers (transmit only one linear polarization), isolators (transmit light only in forward direction), and circulators (separate light traveling in forward and reverse directions). For user convenience, most are available in either pigtailed or NoTail versions. The NoTail versions are convenient for laboratory use and storage, as they have no external pigtails. NoTail 1 and 2-port components have almost no internal fiber and are useful for applications that require minimizing optical path length. NoTail 3 and 4 port components have mounting magnets and are useful for setups on an optical table.
