FIBERTOP launches new 400G CFP2-DC DWDM digital coherent optical module

FiberTop launches the innovative 400G CFP2-DCO DWDM digital coherent optical module, providing a new solution for optical communication networks. This article describes the features and benefits of this new product.

The 400G CFP2-DCO coherent optical module uses a 104-pin CFP2-MSA electrical connector for connecting the host card. The module has following system performance and features:

• Operating rate up to 425 Gbps
• PM-QPSK (200G) and PM-16QAM (200G / 400G) and PM-16QAM PS (200G) modulation formats
• 100GE, 200GE, 400GE and OTU4 / OTUCn services 
• OTL4.4, FOIC1.4, CAUI-4 and FOIC1.2 electrical interfaces
• Near-end / remote-end data loopback
• CFP2 MSA Hardware Specification 1.0 with modifications compliant
• CFP MSA Management Interface Specification 2.2 with modifications compliant
• OTN framer and Ethernet MAC/PCS
• LLDP packet listening
• Hot-pluggable CFP2 form factor

The optical module consists of three functional parts: TX module, RX module and control module. All the control interface pins are provided by an internal microcontroller. This microcontroller can also be used for modulator control, software management, and alarm / performance event reporting.

FiberTop's 400G CFP2-DCO DWDM digital coherent optical module provides excellent transmission capabilities. It supports DWDM (Dense Wavelength Division Multiplexing) technology, capable of transmitting multiple signals of different wavelengths simultaneously on a single optical fiber. In high-density data centers or transmission networks, high-bandwidth transmission can be achieved, greatly improving the scalability and capacity of the network.

 Secondly, the module is highly adaptable and flexible. It is capable of transmission within a range of 120 kilometers to 1200 kilometers. With more choices and customized configurations, it is suitable for different network topologies and distance requirements.
