MEMS DUAL 4x4 MULTICAST SWITCH
DiCon’s MEMS Dual 4x4 Multicast Switch is based on DiCon’s
proven MEMS 1xN Switch, and incorporates two 4x4 Multicast
Switches for add/drop functionality in a single package. For the
drop side, input signals are first broadcast via 1x4 optical splitters
into 4 optical switches, which are then used to independently route
network traffic from any input to any or all output ports. For the
add side, each switch receives an input and selects one of the N
splitters to receive traffic for broadcast to the network. The MEMS
Dual 4x4 Multicast Switch is ideal for colorless, directionless and
contentionless add/drop multiplexing.
FEATURES
Compact Form Factor
Excellent Thermal Stability
Proven MEMS Durability and Reliability
APPLICATIONS
DiCon’s MEMS Multicast Switches are intended for colorless, directionless and
contentionless add/drop multiplexing in ROADM networks.

On the Add Side, a series of MEMS 1xN optical switches are used
to direct each input to a requested output. Splitters are then used on
each output to collect and combine the light from the switches, so that
each output can contain any requested combination of inputs.

goes to which output. In this way each output can contain the signal
from any requested input.

OPTIONS
The MEMS Dual 4x4 Mulitcast Switches can be customized to best
meet the applications requirements, and two standard options are
available as follows:
1) Upgrade ports can be added to the Add and Drop sides.
2) Tap Detectors to monitor the input and output power.
