Concepts and Features of N4917BSCB Software
Software Concept and Flow of Optical Receiver Test
The N4917BSCB solution software controls the complete hardware
required to perform an automated stressed signal calibration and system
performance test in accordance with IEEE 802.3bs (clauses 121, 122, and
124) and IEEE 802.3cd (clauses 138, 139, and 140) specifications for the
following standards:
• 200GBASE-FR4/-LR4/-DR4 (IEEE 802.3bs)
• 400GBASE-FR8/-LR8 (IEEE 802.3bs)
• 400GBASE-DR4 (IEEE 802.3bs)
• 400G-FR4 (100G per lambda MSA)
• 100G-FR/-LR (100G per lambda MSA)
• 100GBASE-DR (IEEE 802.3cd)
• 50G-SR/100G-SR2/200G-SR4/400G-SR8 (IEEE 802.3cd)
• 50G-FR/-LR (IEEE 802.3cd)
The software is based on a generic framework that already supports a wide
range of automated compliance test applications for electrical
transmission standards, such as, OIF CEI, XAUI, CAUI and many others.
The workflow of a generic compliance test application consists of five basic
steps, which are explained in detail in
The following table briefly explains each of these steps in the workflow.
Step
Description
Set Up
Select standard to be tested and specify
instrument connection settings.
Select Tests
Adjust your equipment setting using Utility
Functions and select tasks to perform from the
list of available tests. The list of available tasks
depends on the selected transmission standard
and equipment configuration.
Configure
Adjust specific test settings (in compliance or
debug mode).
Connect
Check the actual hardware connection with the
provided reference diagram.
Run Test
Run the selected tests (either once or multiple
times).
