ECPO-QDDZR400G

400G QSFP-DD ZR Coherent Transceiver

The ECPO-QDDZR400G is a 400Gbps tunable dense wavelength division multiplexing (DWDM) DP-16QAM coherent transceiver. The QSFP-DD form factor device is hot pluggable and includes digital diagnostics monitoring (DDM) and control functions. This module enables interoperable and cost-effective solutions (OIF Type-1) for WDM transmission links up to 120 km. 

Overview

The ECPO-QDDZR400G is a 400Gbps tunable dense wavelength division multiplexing (DWDM) DP-16QAM coherent transceiver. The QSFP-DD form factor device is hot pluggable and includes digital diagnostics monitoring (DDM) and control functions. This module enables interoperable and cost-effective solutions (OIF Type-1) for WDM transmission links up to 120 km. This transceiver employs coherent optic techniques and its key components include a nano-integrable tunable laser assembly (ITLA), a 7-nm coherent digital signal processing (DSP) chip, and a silicon-photonics-based coherent transmitter and receiver optical assembly (COSA). The transceiver supports one 400GAUI-8 (PAM4) Ethernet interface on the client side, which is fully compatible with an IEEE 802.3 400GAUI-8 C2M to OIF 400GE-ZR client/host system. The transceiver uses a single-carrier 60 GBaud coherent DP-16QAM modulation format on the line side. Concatenated FEC (C-FEC) enables a post-FEC error floor of <1e-15 with a pre-FEC BER threshold of 1.25e-2. The transceiver can be conveniently plugged into the host system through its pull tab, which is blue by default. The transceiver operates from a single +3.3 V power supply over an operating case temperature range of 0°C to +70°C. The housing is made of metal for EMI immunity. The common management interface is implemented as a two-wire interface (I2C bus) for serial ID, digital diagnostics, and module control functions. An enhanced digital diagnostics monitoring interface allows real-time access to the device for monitoring transmitted optical power, received optical power, SNR, BER, and laser wavelength, etc.
