A gigabit interface converter (GBIC) or a small form-factor pluggable (SPF) are transceivers that convert electrical signals into optical signals and vice versa. They generally transmit data at high speeds, typically 1 Gbps or faster. SPFs are primarily small form factor versions of GBICs.
As you mentioned, a gigabyte converter and SPF primarily act as physical medium converters (electrical to optical transceivers) and the built-in EPROM (programmable read-only memory) modules primarily provide information describing the transceiver's capabilities, standard interfaces and manufacturer. Thus, GBIC and SPF records don't usually exist. I see no issue with moving these devices between systems.
