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.
