/**
 * Coriant OEM Transceiver Catalog Seed
 *
 * Seeds Coriant-branded transceiver PIDs for WDM platforms:
 * hiT 7300, hiT 7100 series, and Groove G30.
 *
 * Note: Coriant was previously Tellabs/Siemens/Nokia Siemens Networks.
 * Coriant was acquired by Infinera in 2018. These PIDs cover legacy
 * Coriant WDM platform optics and are distinct from infinera-oem.ts
 * which covers modern Infinera HIL PIDs.
