N1078A Keysight optical/electrical clock recovery

The Keysight N1078A optical/electrical clock recovery module provides standards-compliant clock recovery for PAM4 and NRZ single-mode optical and electrical signals from 125 MBd to 64 GBd.

• With 125 MBd to 64 GBd data rate range (continuous), supports optical/electrical NRZ and PAM4 data signals

• Adjustable peak and loop bandwidths (up to 20 MHz) to provide standards-compliant clock recovery ("ideal PLL")

• Built-in variable equalizer (option EVA) locks out quality degraded signals ("closed eye diagram")

• In-depth analysis of the root cause of jitter using the jitter spectrum analysis function (option JSA)

• Perform standards-compliant PLL bandwidth and peak measurements with the N1010300A FlexPLL application software and N1081PLCA PCI Express PLL test application software

Accessories include

• USB cable (for connection to the DCA-X host or user's PC)

• Power cable

Core Performance Advantages

1. Ultra-wideband Analysis Capability

Provides 65 GHz optical modulation analysis bandwidth (industry-leading level), precisely supporting 112 Gbaud PAM4 signal testing, and meeting the R&D and verification requirements for 800G/1.6T optical modules.

2. Mass Production-level Test Efficiency

Achieves multi-machine parallel synchronization through the AXIe modular architecture, with a single system scalable up to 8 channels, increasing test throughput by 400% and significantly reducing optical module production costs.

3. Intelligent damage analysis functionality

Integrates real-time noise injection and channel damage simulation, supporting OMA tolerance testing and TDECQ closed-loop optimization, helping to improve product yield.
