NeoPhotonics Announces CFP2-DCO Module Transmission of 400 Gbps over 1500 km in a 75 GHz-spaced EDFA Only DWDM System
NeoPhotonics CFP-DCO Coherent Pluggable Modules Extend Use Cases to Metro, Regional and Long Haul Networks
To achieve 1500 km reach and a 400G data rate, the modules were operated at 69 Gbaud using 16 QAM modulation. Probabilistic constellation shaping and a soft-decision forward error correction codec were used to achieve a required OSNR of approximately 20 dB, which is comparable to coherent line card port performance from leading chassis-based coherent systems. The modules each consumed considerably less electrical power than line card solutions operating at comparable data rates and distances.
These 400G CFP2-DCO coherent pluggable transceiver modules use
- Class 40 CDM: NeoPhotonics Class 40, polarization multiplexed, quadrature coherent driver modulator (CDM) features a co-packaged InP modulator with a linear, high bandwidth, differential driver, and is designed for low V-Pi, low insertion loss and a high extinction ratio. The compact package is designed to be compliant with the form factor of the OIF Implementation Agreement #OIF-HB-CDM-01.0.
- Class 40 Micro-ICR: NeoPhotonics Class 40 High Bandwidth Micro-Intradyne Coherent Receiver (Micro-ICR) is designed for >60 GBaud symbol rates. The compact package is designed to be compliant with the OIF Implementation Agreement OIF-DPC-MRX-02.0.
- Nano-ITLA: NeoPhotonics Nano-ITLA is based on the same proven and reliable high performance external cavity architecture as NeoPhotonics’ industry leading Micro-ITLA and maintains comparable ultra-narrow linewidth, low frequency phase noise and the low power consumption in a compact package approximately one half the size.
NeoPhotonics Multi-Rate CFP2-DCO modules are fully qualified. Telcordia testing has been successfully extended to 2000 hours of High Temperature Operating Life (HTOL) testing, showing the high reliability and performance of NeoPhotonics CFP2-DCO platform.
Multi-Rate CFP2-DCO modules supporting Metro (64 Gbaud/DP-16 QAM) and Long Haul (64 Gbaud/DP-QPSK) applications are shipping in General Availability.
“Coupled with our recent demonstration of 800 km 400 Gbps transmission using our 400ZR+ QSFP-DD, our CFP2-DCO 400G 1500 km transmission brings the use of pluggable modules in regional and long haul networks closer to reality,” said
