Mini Single Window Single Mode
Fiber Coupler
Mini SWFC Series
Product Description
The Oplink mini fused single window wideband fiber 1x2 (2x2) couplers provide ac-
curate optical signal coupling and splitting over wide bandwidth with high performance
and high reliability in miniature or sub-miniature package. These couplers have excel-
lent uniformity, low excess loss and very low polarization sensitivity and are available
with various tap ratios, wavelength ranges, fiber types, and connector options.The small
form factor with reduced cladding fiber is essential for compact system integration. All
devices are shown to be able to handle high optical power up to 4W and are tested
according to industry standard procedures. Reliability is guaranteed through stringent
tests to fully meet Telcordia GR-1221 requirements.
Oplink can provide customized designs to meet specialized feature applications. Also,
Oplink offers modular assemblies that integrate other components to form a full func-
tion module or subsystem.
