1×2 Single-Mode Single-Window Coupler
Provides a variety of narrowband and broadband single-mode 2x2 fiber couplers, as shown in the table on the right. Couplers with two center wavelengths, 1310 and 1559 nm, are provided below. Their bandwidth can be ±40 nm, and coupling ratios of 50:50, 90:10 and 99:1 are available. In addition, these couplers are bidirectional, only allow port 1 to be used as the input port, and integrate SMF-28e+ fiber with a Ø900 µm jacket. These couplers come with FC/PC or FC/APC connectors, or without connectors. If a custom connector configuration is required, please contact
