56 Gbps Laser Drivers
Maximize your DataCom performance while minimizing your power consumption with laser drivers that result in well-behaved (easily equalizable) optical signals.
Coherent has a long history developing high-performance drivers for a wide range of lasers used in our DataCom transceivers and related. These drivers are now offered as standalone products matched for DFBs, VCSELs, and the latest Buried Heterostructure (BH) lasers.
56 Gbps Laser Drivers
Use these smart and versatile drivers for either PAM4 or NRZ modulation. With full programable control of bias and burn-in currents, plus modulation amplitude.
