Abstract: According to an aspect of an embodiment, operations may include receiving an Ethernet signal. The operations may further include creating a bitstream from the Ethernet signal which may include a payload of client information and a set of padding bits. The operations may also include encrypting, using an encryption scheme with an encryption key for a set number of bits, a total payload wherein the total payload may include a combination of the payload of client information and at least one bit from the set of padding bits such that the total payload is divisible by the set number of bits. Further, the operations may include generating a frame from the bitstream which may include the total payload.

Abstract: According to an aspect of an embodiment, operations may include receiving a first Ethernet signal having a first data rate less than a second data rate, the second data rate being a ZR data rate. The operations may also include dividing the first Ethernet signal into a plurality of first-signal sub-signals that each have a third data rate that is less than the first data rate. Moreover, the operations may include generating a second Ethernet signal having the second data rate, the generating of the second Ethernet signal being based on the plurality of first-signal sub-signals such that the second Ethernet signal includes the plurality of first-signal sub-signals. Further, the operations may include providing the second Ethernet signal to a ZR network such that the second Ethernet signal is a ZR signal.
