Sinabi ni Rof-PM-UV series Low-Vpi phase modulatoray may mababang boltahe ng kalahating alon(2V), mababang insertion loss, mataas na bandwidth, mataas na damage na katangian ng optical power, huni sa high-speed optical communication system ay pangunahing ginagamit para sa light control, phase shift ng coherent communication system, sideband ROF system at bawasan ang simulation ng optical fiber communication system sa Brisbane deep stimulated scattering (SBS), atbp.
