IDT offers directly modulated laser (DML) and vertical cavity surface emitting laser (VCSEL) drivers for optical networking applications.

IDT's DML driver arrays are designed specifically for distributed feedback (DFB) laser diode applications. The portfolio includes single channel and quad channel solutions for distances of 100's of meters to 10km, including CWDM4, PSM4, CLR4, and PAM4. The DML drivers support the client side with bit rates up to 28.05Gbps and are integrated into QSFP or other form factors.

IDT's VCSEL drivers are designed for Ethernet and other short reach applications. IDT's VCSEL driver portfolio of single and multi-channel devices provide customers with a high-performance, high-data-rate, low-power, and low-emissions solution for the datacenter and consumer space. IDT’s VCSEL drivers and TIA+PA receiver arrays enable chip-to-chip, board-to-board, and system-to-system optical interconnects, removing the constraints of copper cabling and enabling the realization of higher data rates with significantly less EMI and power consumption.
