Interleaver Specification Sheet

F i n i s a r
The Finisar 50G Interleaver efficiently demultiplexes (or multiplexes) 50G
spaced channels into two sets of 100G spaced channels, which is the best
solution to upgrade the existing 100G spacing system and cost saving to
the equipment manufacturer. This passively athermalized interleaver offers
exceptional performance in an ultra-compact form factor
.
