The Tyco Electronics’
LIGHTPLANE Connector
is a multi-position fiber
optic backplane connector
that permits blind mating
of singlemode or
multimode optical fibers
from a daughtercard to
a system backplane or
motherboard. Now you
can simultaneously make
both the optical and
electronic interconnections
when installing the
daughtercard. The
LIGHTPLANE connector
contains up to 8 fiber
positions utilizing the
standard SC interface.
Use of off the shelf SC com-
ponents minimizes per line
costs. It also eliminates the
need for separate optical
jumpers from the daughter-
cards to the front or back
of the cabinet, minimizing
labor costs and possible
fiber damage.
Designed for telecommuni-
cations and networking
equipment, the
LIGHTPLANE connector
provides performance
comparable to conventional
SC interconnections: 0.5 dB
typical insertion loss and
40 dB return loss. Shoulder
screws on the daughtercard
module provide the
necessary float for precise
alignment. Daughtercard
termini are spring loaded
to ensure optical contact
between the backplane
and daughtercard. The
daughtercard connector
acts like multiple SC
connectors, providing fiber
density and minimizing
packaging all in one
protective shell. The shell
protects the optical contacts
on all sides from accidental
damage if the board is
dropped or knocked
against a hard surface.
