Description
The RR4-C145 is an advanced 4-channel ring resonator modulator designed for high-speed optical communication applications. Operating in both O-band (1310 nm) and C-band (1550 nm), this modulator delivers a 3-dB electro-optical bandwidth exceeding 145 GHz, making it a key enabler for next-generation transceivers and data transmission at 200 GBaud PAM4.
With a lumped, low-capacitance RF design, the RR4-C145 offers superior performance with an insertion loss below 6 dB, a static extinction ratio greater than 8 dB, and an ultra-low Vdrive of less than 1 V @ 50 Ohm.
The compact chip integrates RF and DC interfaces on the same edge, ensuring ease of integration into high-speed systems. Engineered for probing with GSG probes for GS operation, the RR4-C145 supports optical input power up to 13 dBm and operates reliably between -40°C and 85°C, ensuring long-term stability with 8000 hours of operation at 20°C with minimal Vdrive degradation.
Also available as a single-channel configuration, the RR4-C145 provides unmatched flexibility for a wide range of optical interconnect solutions.
