本标准适用于以光缆为传输媒质,在短距离内作广播专用彩色电视节目和单声、立体声及多路声音节目的传输通路。短程光缆传输系统系指通过光缆的无中继的短距离传输系统(简称短程线)。本标准亦适用于光缆传输系统的多重频分复用和双向传输。系统的调制方式无论是基带强度调制(BB—IM)、预调制(包括FM—IM、PFM—IM 等)还是数码调制(包括PCM—IM 等)一律按本标准执行。
This standard applies to fiber optic cable as the transmission medium for making short-distance broadcast of dedicated color television programs and mono, stereo and multi-channel sound transmission channel. Short-haul optical cable transmission system refers to the relayless short-distance transmission system (referred to as the geodesic) through the optical cable. This standard also applies to optical fiber transmission system multiple frequency division multiplexing and two-way transmission. The modulation method of the system shall be performed according to this standard whether it is baseband intensity modulation (BB-IM), pre-modulation (including FM-IM, PFM-IM, etc.) or digital modulation (including PCM- IM)
