Manufacturer of Low-Power Optical Modules NRZ

MACOM and Broadex Technologies are key manufacturers offering low-power optical modules with NRZ modulation for 50G and short-reach applications. Key Manufacturers and ProductsMACOM offers the PRISM-50D™ MATP-05026 device, a 50G PHY supporting both PAM4 and NRZ modulation. This highly integrated device is designed for low latency, low power, and compact optical transceiver modules such as QSFP28, SFP-DD, and DSFP.

It includes an integrated modulator driver and on-board management processor, simplifying module implementation and reducing BOM costs, making it suitable for low-power NRZ optical modules. Broadex Technologies provides 50G optical transceiver modules that support 2-lane 25G NRZ electrical interfaces. These modules are built using COB technology, offering high reliability and cost-effectiveness for short-reach links up to 40 km.

Z modulation in these modules ensures lower power consumption and high signal-to-noise ratio, making them ideal for enterprise networks and latency-sensitive applications.

Advantages of NRZ for Low-

Power ModulesNRZ (Non-Return-to-Zero) is a binary modulation scheme where each symbol represents one bit. Its simplicity provides several benefits for low-power optical modules: Lower power consumption due to simpler transmitter and receiver circuitry. High signal-to-noise ratio (SNR) and low bit error rate (BER), especially for short-distance links.

Compatibility with existing 25G network infrastructure, reducing deployment costs. Reduced complexity compared to PAM4, which requires advanced DSP and higher power.
