OADM
The ONS 15454 SDH Optical Add/Drop Multiplexer (OADM) cards are divided into two groups: band OADM cards and channel OADM cards. Band OADM cards add and drop one or four bands of adjacent channels. They include the 4-Band OADM (AD-4B-xx.x) and the 1-Band OADM (AD-1B-xx.x). Channel OADM cards add and drop one, two, or four adjacent channels. They include the 4-Channel OADM (AD-4C-xx.x), the 2-Channel OADM (AD-2C-xx.x), and the 1-Channel OADM (AD-1C-xx.x).
The Mesh/Multiring Upgrade Unit (MMU) card is also considered an OADM card. It supports multiring and mesh upgrades for ROADM nodes in both C-band and L-band. Mesh/multiring upgrade is the capability to optically bypass a given wavelength from one section of the network or ring to another one without requiring 3R regeneration. You can install the MMU card in Slots 1 through 6 and 12 through 17.
