Meets Qualification requirements of Telcordia / Bellcore GR468-Core for central office environment.
Operating reliability <500 FITs1 in 15 years.
1 - Assumes laser die submount is held within the range 8°C to 50°C by the internal thermoelectric cooler and the product is
deployed in equal quantities on each of the four channels with a mean forward current of 35 mA. End of life limits based on 10 mA
increase in Ith and 25% change in laser efficiency. FIT rate data for other end of life criteria, including minimum extinction ratio
requirements, are available on request.
