ETSI ETSI TS 105 175-1-2 V1.1.1 (2015-04) 7 1 Scope The present document provides a
37、description of an OSI physical networking layer to communicate data over plastic optical fibre at 100 Mbit/s and 1 000 Mbit/s. A full duplex physical layer is described. Multi data type interface is proposed, as well as its encapsulation, coding and modulation needed to achieve 1 Gbit/s link over a
38、bandwidth limited optical channel like the plastic optical fibre. Multiple link speeds are handled by this physical layer. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
