This device consists of a 4-channel
VCSEL array in a miniature surface-
mountable MT package. It is based on
a unique combination of self-alignment
technology and direct optical coupling
to fiber, resulting in pure beam shapes
and optimum coupling efficiency with-
out need for active alignment.
Applications include parallel Fibre
Channel and optical interconnect
inter/intra-board. And it matches the
4D470 PIN Photodiode Array.
