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.
