1. An optical module, comprising:
first circuitry configured to (i) receive first data transmitted from a host device over an electrical communication link at a first data rate, the first data transmitted from the host device, the first data including peripheral component interconnect express (PCIe) data and compute express link (CXL) data, (ii) change a data rate for transmission of the first data from the optical module, and (iii) transmit the first data from the optical module at a second data rate that is different than the first data rate; and
second circuitry configured to (i) convert the first data transmitted from the host device at the first data rate from an electrical format to an optical format for transmission from the optical module at the second data rate and (ii) convert second data received from an optical receiver at the second data rate from the optical format to the electrical format for transmission from the optical module to the host device at the first data rate via the first circuitry.
