Cisco 400G Digital Coherent BiDi CFP2 Data Sheet

Cisco offers a comprehensive range of pluggable optical modules in the Cisco pluggables portfolio. The wide variety of modules gives you flexible and cost-effective options for all types of interfaces. Cisco offers a range of GBIC, SFP, XFP, SFP+, CXP, CFP, Cisco CPAK, and QSFP+ pluggable modules. These small, modular optical interface transceivers offer a convenient and cost-effective solution for an array of applications in the data center, campus, metropolitan-area access and ring network, storage area network, and long-haul network. In recent times, with longer strides of innovation, Cisco has introduced analog and digital DWDM CFP2 interfaces to the market as well the 400G Digital Coherent QSFP-DD Pluggable Optical Module. All of the above have beed designed for fiber pair transmission. Cisco is now offering the new Cisco 400G Digital Coherent BiDi CFP2 capable of supporting single-fiber bidirectional coherent transmission.

Product overview

Cisco already offers a range of Digital Coherent CFP2 transceivers capable of supporting up to a 400-Gbps wavelength. Thanks to technology miniaturization, Cisco is now able to offer a CFP2 DCO supporting up to 400 Gbps of line rate that can cope with single-fiber bidirectional transmission thanks to the availability of a dual-laser approach between Tx and Rx.

The Cisco 400G Digital Coherent BiDi CFP2 is mechanically compliant with CFP2 MSA hardware. The CFP2 module contains a PCB with a 104-contact card-edge electrical interface to external Host/Client-side logic. The Network Lane Interface is a duplex LC connector coupled to an optical fiber carrying the WDM coherent signal in the C-band.

Features and benefits

The Cisco 400G Digital Coherent BiDi CFP2 key application is the transmission over single fiber of both the TX and RX data streams. To achieve this, an external solution is needed to combine the TX and RX ports of the pluggable as depicted in the following pictures:

Single-fiber bidirectional communication with BiDi CFP2 DCO

Cisco 400G Digital Coherent BiDi CFP2 also provides flexible modulation benefits. As in the case of other Cisco Coherent Pluggable Interfaces (CFP2 DCO and QSFP-DD DCO), Cisco 400G Digital Coherent BiDi CFP2 provides the capability to support multiple bit rates:

100 Gbps with QPSK modulation

200 Gbps with QPSK modulation

400 Gbps with 16-QAM modulation
