TRANSMISSION METHOD, TRANSMISSION EQUIPMENT AND TRANSMISSION SYSTEM

摘要

A transmission method that transmits an optical signal via a plurality of virtual lanes in dual polarization or multi-level modulation includes: receiving a first frame signal of a first frequency and a second frame signal of a second frequency, and storing the first and second frame signals on a memory; reading out the first frame signal from the memory at a third frequency, and inserting a stuff into the first frame signal such that a difference between the first frequency and the third frequency is adjusted to generate a third frame signal; reading out the second frame signal from the memory at the third frequency, and inserting a staff into the second frame signal such that a difference between the second frequency and the third frequency is adjusted to generate a fourth frame signal; and transmitting the third and fourth frame signals respectively via different virtual lanes.

1. A transmission method that transmits an optical signal from transmitting node equipment to receiving node equipment via a plurality of virtual lanes in dual polarization or multi-level modulation, the transmission method comprising:
receiving a first frame signal of a first frequency and a second frame signal of a second frequency, and storing the first frame signal and the second frame signal on a memory in the transmitting node equipment; reading out the first frame signal from the memory at a third frequency, and inserting a stuff into the first frame signal read, out from the memory such that a difference between the first frequency and the third frequency is adjusted to generate a third frame signal; reading out the second frame signal from the memory at the third frequency, and inserting a stuff into the second frame signal read out from the memory such that a difference between the second frequency and the third frequency is adjusted to generate a fourth frame signal; and transmitting the third fame signal and the fourth frame signal respectively via different virtual lanes.
