A preamble which consists primarily of data pulses and inverted power pulses is used initially to obtain the parameters for and to set up a phase locked loop. For example, an edge-triggered one-shot circuit can be used to generate a reference clock from the preamble until lock is detected.

The phase lock loop, which is in the secondary, is kept in phase during normal communication using valid Manchester edges from the transmit signal.

Abstract: In optical two-way communication using a single optical fiber, part of the light transmitted from an apparatus is received as stray light by the apparatus itself. This occasionally hampers accurate detection of disconnection from the partner apparatus and of the start of data communication by the partner apparatus after the establishment of connection. To overcome this, the timing with which an apparatus transmits a tone signal after the establishment of connection is compared with the timing with which the apparatus receives a tone signal from the partner apparatus, and the two apparatuses use different sets of data transmission properties (for example, different wavelengths) to accurately detect disconnection. Moreover, based on the properties of the received light and the characteristics of the receiving amplifier, repetition of the same code for longer than a predetermined period is detected to accurately detect disconnection.

Abstract: In a multi-carrier transmission scheme (frequency domain multiplexed—FDM), a single high rate data stream is split into multiple lower rate data streams each transmitted over a different carrier (e.g., a tone or bin). The data rate possible from a multiple-carrier transmission scheme is theoretically equivalent to the data rate possible from a single-carrier (including baseband) scheme with the same composite bandwidth. The scheme allows for a communications system that can selectively send each data signal (e.g., audio data, video data, raw data, etc.) partitioned out into full and half duplex sections (e.g., tones). The scheme can have a reduced complexity and cost and use less bandwidth. This is done by being able to selectively split a data signal into both full and half duplex tones.
