48 Gb/s Pattern Generator, Dual 24 Gb/s Channel (PG2402)

Data Sheet

Product Overview

The Optilab PG2402 is a Dual 24 Gb/s Pattern Generator (PG) combined, for 48 Gb/s. This high performance pattern generator unit provides up to 24 Gb/s eye diagram generation for Bit Error Rate Testing (BERT). The user selectable reference clock allows testing BER at a specific data rate with external clock input or at a predefined data rate using the internal clock. A high speed synchronized clock at half or full data rate is available for eye pattern monitoring or RZ pulse generation. An intuitive GUI, Optilab Teraport, is provided with the BERT system for easy operation. Contact Optilab for more information.
