The 648-type CoC is a high coupling efficiency optical subassembly consisting of an electro-absorption modulated laser(EML) and PIN monitor diode mounted on a metalized silicon chip platform, with a focusing aspheric lens.  The CoC has been purged and electro-optically tested to support ultra-stable 10-Gb/s applications. The CoC uses Broadcom's 294Y-type high-performance 10G EML die.


  • Capable of transmission up to 10.7 Gb/s
  • For use up to 40 km in standard single-mode fiber at 10 Gb/s, with C-band DWDM wavelengths available
  • Designed for high power and high coupling efficiency
