HFAN-02.0.1: Parasitic Inductance Effects in 10Gbps Fiber Optic Design


Successful 10Gbps optical module design demands careful attention to the sources and effects ofparasitic inductance. The addition of even 0.1nH of inductance can cause significant degradation to therise/fall times, overshoot/ringing, and jitter in the optical output (for reference, a 0.5mm bond wire addsapproximately 0.4nH).
