MDA and LED specifications
See the following sections for Media Dependent Adapters (MDAs) and
Light Emitting Diode (LED) specifications.
MDA specifications
The OC-3c/STM-1 MDA uses SONET STS-3c/SDH STM-1 1300
nanometer (nm) optical transceivers with MT-RJ fiber-optic connectors and
either single mode fiber (SMF) or multimode fiber (MMF) cabling.
The following table describes the 8672ATME and 8672ATMM modules
MDA specifications of OC-12c/STM-1 and OC-3c/STM-4 port type.
