48 Gb/s Bit Error Rate Tester, Dual 24 Gb/s CH (BT2402)

Data Sheet

Product Overview

The Optilab BT2402 is a Dual 24 Gb/s Bit Error Rate Tester (BERT) combined, for 48 Gb/s. This high performance BT2402 provides an easy solution for bit error rate testing of (D) QPSK system with data rate up to 48 Gb/s. The Optilab BT2402 consists PG2402 Pattern Generator and EA2402 Error Analyzer. 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.
