About

SCHOTT TO PLUS® on footprint of TO 46 are suitable to be used in GPON, XG-PON,  10GEPON, CPRI and 32G Fiber Channel. Single Channel or Quad for use in SFP28 or QSFP28 (CWDM4) transceivers.

Product features

  • Short wire-bonds reduce inductance, increase speed.
  • Matched with high-refractive index ball lens caps, molded lens caps, angled window caps.
