Cost effective VCSEL array based 80-Gb/s TOSA for NG-PON2

摘要

The 8×10 Gb/s TOSA based on a VCSEL array was successfully developed for NG-PON2 application. For the cost effectiveness, direct optical coupling without lens array was used to package the TOSA. We have found that an optical and electrical crosstalk was small enough not to effect on a transmission performance.
