GigOptix announces successful Telcordia high temperature operating lifetime testing results for its 40G DPSK optical modulator
PALO ALTO, USA: GigOptix Inc., a leading supplier of high performance electronic and electro-optic components that enable next generation 40G and 100G optical networks, announced that as part of the ongoing productization of its Thin Film Polymer on Silicon (TFPS) line of Mach-Zehnder Modulators (MZM), that its LX8401 40G DPSK MZMs has successfully passed prequalification assessment with over 1000hrs of Telcordia’s GR-468 demanding High Temperature Operating Lifetime (HTOL) testing without degradation in operating performance.
The HTOL test is a key milestone in the required suite of Telcordia GR-468 reliability assessments. The HTOL test assesses the reliability of the TFPS MZM by stressing the device at a temperature of 85C while the device is modulating a 1550nm laser and is driven by a high speed electrical RF signal. This test simulates an accelerated 25 year lifetime of the product.
After 1000 hours, the pre-qualification modulators showed no degradation in performance. The performance parameters measured included insertion loss, drive voltage, extinction ratio, and bandwidth. This successful result builds on previously announced reliability assessments by GigOptix of its TFPS optical chips, which have been measured successfully for over 7000hrs at 85C to date.
