Optical transmission converter, memory system comprising same, and related method of operation

A memory system comprising:

• a host device comprising an electro-optical converting device that converts a command, an address, and data to an optical signal;
• and
• multiple slave devices comprising an optical transmission converter that converts the optical signal to an electrical signal,
• wherein the optical transmission converter comprises:
• a wavelength selector that outputs a reception wavelength selection signal and a transmission wavelength selection signal in response to a wavelength control signal;
• an opto-electrical converter that converts a selection optical signal to a reception electrical signal based on a reception optical signal corresponding to the command, the address and the data from a host device and the reception wavelength selection signal;
• and
• an electro-optical converter that converts a transmission electrical signal to a transmission optical signal based on the transmission wavelength selection signal and the transmission electrical signal.

A method, comprising:

• outputting, by a wavelength selector, a reception wavelength selection signal and a transmission wavelength selection signal in response to a wavelength control signal;
• converting, by an opto-electrical converter, a selection optical signal into a reception electrical signal based on a reception optical signal from a host device and the reception wavelength selection signal;
• and
• converting, by an electro-optical converter, a transmission electrical signal into a transmission optical signal based on the transmission wavelength selection signal and the transmission electrical signal.
