2×2 (1310/1550) Dual Window Coupler
Lightel offers a variety of narrowband and broadband single-mode 2x2 fiber couplers, as shown in the table on the right. Their bandwidth can be ±40 nm, with coupling ratios such as 50:50, 90:10 and 99:1 available, and these ratios accept batch customization. In addition, these couplers are bidirectional, allow any port to be used as the input port (see the 2x2 coupling example tab above), and incorporate SMF-28e+ fiber with Ø900 µm jacket. These couplers come with FC/PC or FC/APC connectors, or without connectors. If you need a custom connector configuration, please contact sales@lightel.cn or the engineer you have already communicated with.
