The filter is
used for selecting one wavelength light from the mixed
lights, which will be filtered, in the meanwhile,
letting the other wavelength light pass through. There
are two kinds of filters available: 131 Onm pass/1550nm
stop, and 1550nm pass/131 Onm stop. We employ FBT
technique fabricating standard 1310/1550nm filters, they
have very good performance and enirvemential stability
in applications, according to the outcome of experiments
and the customer's
feedback. |
