据《Telephony》1986年9月刊报道:Lee′s Data Communictions公司的1024T-1型全双工光纤modem具有39dB光系统增益,并带有VCXO-PLL时钟恢复电路和嵌入的报告序列告警器。一对内连到电缆上的modem在两部终端上提供1.544Mb/s高速无差错的数据通信。该设备可以从数据流中提取时钟信息,并能用这种信息重新调整数据进入的时间。
According to Telephony, September, 1986, Lee’s Data Communications’ 1024T-1 full-duplex fiber modem has 39dB optical system gain with VCXO-PLL clock recovery circuitry and an embedded report sequence alarm. A pair of interconnectors connected to the cable provides 1.544 Mb / s high-speed, error-free data communication on both terminals. The device can extract clock information from the data stream and can use this information to readjust the time of data entry.
