IEEE Trial Use Standard for Information Processing Systems-Local Area Networks-Part 5: Token Ring Access Method and Physical Layer Spec.-Fiber Optic Media Station Attachment
IEEE信息处理系统局域网试用标准第5部分:令牌环访问方法和物理层规范光纤媒体站附件
This Technical Report specifies the functional, electrical, optical, and mechanical characteristics of a fibre optic interface for connecting a 4- or 16-Mbit/s token ring station to the trunk coupling unit (TCU) of a token ring. It is based upon a fibre optic transmitter, a channel of multimode graded-index fibres, and a direct-detection photodiode receiver; and includes signalling provisions for bypass of the station from the ring and self-test capabilities.
