ILU-C-50G

Inter Leaver unit (ILU) is used to expand the DWDM channel capacity up to 80 channels. Inter leaver combines the 100GHz spacing even and odd wavelengths into 50GHz signals. When used in transmit direction Inter leaver combines the two streams of incoming optical wavelengths spaced at 100GHz and gives output wavelengths at 50GHz signals. In receive direction the 50GHz spacing in-coming signals are separated into two streams of 100GHz signals.

Both MDU40E-D and MDU40O-D are used with an optical interleaver unit (ILU-C-50G) to provide 80 Channel aggregations in a pair of fiber at 50GHz.

Power specifications

It is purely a passive card or unit.

Visual indicator details

There is no LED visual indication for this card or unit

Functional description

Following is a schematic of the MDU40E-D and MDU40O-D unit connectivity. One for the multiplexing and one for the demultiplexing need to be used. Each is a half slot card which needs to be housed in the optical adaptor card.

Typical specifications

Typical specification and functionalities of the ILU-C-50G card are as follows:

• Support two C-band 100GHz DWDM 40 channels.
• Multiplexes two sets of 100GHz 40 Channels to one set of 50GHz 80 channels and demultiplexes from 80 channels to two 40 Channels.
• Purely passive, housed in the optical adaptor card.
