Active Optical Modules (AOMs) using NRZ technology provide high-speed, reliable optical data transmission for applications up to 100Gbps, supporting both short- and medium-range links.

Overview

Active Optical Modules (AOMs) are fiber optic transceivers that convert electrical signals into optical signals for high-speed data transmission.

NR

Z (Non-Return-to-Zero) modulation is a widely used signaling method in these modules, offering simplicity and compatibility with existing network infrastructure. NRZ-based AOMs are commonly deployed in data centers, enterprise networks, and telecommunications systems in Australia and globally.

Key Specifications

Data Rates: NRZ AOMs support speeds such as 25Gbps per lane, aggregated to 100Gbps over 4 lanes (QSFP28) or 50Gbps per lane for 50G modules. Channel Configurations: Modules are available in 4-channel (4TX+4RX) or 12-channel half-duplex configurations, allowing flexible deployment depending on bandwidth requirements. Distance: Depending on the module type, NRZ AOMs can transmit over distances ranging from 2 km (single-mode fiber) to 70 m (multi-mode fiber) for high-speed links.

Wavelengths: Commonly use 850nm for multi-mode fiber and 1310nm for single-mode fiber, supporting standard Ethernet protocols like 100GBASE-PLR4L. Temperature Range: Some ruggedized modules operate in extended temperature ranges from -40°C to +85°C, suitable for harsh environments.

Advantages of NR

Z AOMsSimplicity and Reliability: NRZ modulation is less complex than PAM4, reducing signal processing requirements and improving reliability for short- to medium-range links. Backward Compatibility: Many NRZ modules are backward compatible with lower-speed standards, allowing gradual network upgrades without redesigning the circuit card assembly.

Hot-

Pluggable: Modules like QSFP28 NRZ are hot-swappable, enabling easy installation and maintenance in live networks. Compact Design: Suitable for space-constrained environments, with efficient heat management for high-density deployments.

Applications

Data Centers: High-speed interconnects between servers, switches, and storage systems. Telecommunications: Backbone and metro networks requiring reliable 25G/50G/100G links. Enterprise Networks: Core and distribution layers where high throughput and low latency are critical.

Testing and Validation: Optical clock recovery modules (e.g., MATE-10010A) support NRZ signals for performance testing and measurement.

Considerations

While NRZ AO

Ms are robust and widely used, PAM4 modulation is increasingly adopted for higher data rates (200G and above) due to its ability to double the data throughput per lane. However, NRZ remains a cost-effective and reliable choice for many existing network deployments, especially where distances are moderate and simplicity is preferred. In summary, Australian Active Optical Modules using NRZ technology provide a versatile, high-performance solution for modern networking needs, balancing speed, reliability, and ease of deployment across various applications.

There have been multiple variants of the electrical interface of optical modules that have been used over the years. The earliest forms of optical modules had an analog NRZ electrical interface. In the transmit direction, the optical module would directly drive the laser or LED with the analog signal coming from the front system card. In the receive direction, the module would directly drive the receive electrical interface with the o
