ETSI TS 105 175-1-2提供了OSI物理网络层的描述，用于通过塑料网络进行数据通信 100 Mbit/s和1000 Mbit/s的光纤。描述了全双工物理层。提出了多数据类型接口，以及实现1Gbit/s所需的封装、编码和调制 通过带宽有限的光纤通道（如塑料光纤）进行链接。多个链路速度由这个 物理层。

ETSI TS 105 175-1-2 provides a 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 bandwidth limited optical channel like the plastic optical fibre. Multiple link speeds are handled by this physical layer.
