Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

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 Digital Coherent 400G DWDM ZR+ as well as interfaces to the market. The latest addition to the Cisco portfolio pushes this boundary further with the introduction of the 400G QSFP-DD High-Power (Bright) Optical Module.DP04QSDD-HE0

Product overview

Cisco is now expanding the range of 400G Digital Coherent QSFP-DD transceivers, introducing High Tx Power variants (+1dBm of Tx Power). Thanks to the miniaturization of the technology with a 7-nm manufacturing procedure and innovation in silicon photonic technology, it is now possible to also squeeze an Optical Amplifier (Mini-EDFA) within a QSFP-DD form factor.

Cisco 400G QSFP-DD High-Power (Bright) Optical module’s small size and low power make it an optimal choice for a wide range of DCI/Cloud, metro access/aggregation, wireless backhaul, and campus interconnect applications.

Cisco 400G QSFP-DD High-Power (Bright) Optical module is mechanically compliant to the QSFP-DD Type 2A Module Specification. The QSFP-DD module contains a PCB with a 76-contact card-edge electrical interface to external host-side logic. The media interface is a duplex LC connector coupled to a 1550-nm optical fiber carrying the DP-mQAM coherent signal. The signaling operates in the C-band.

Two product variants are available:

1.     Ethernet Variant (DP04QSDD-HE0)

2.     Multirate OTN/Ethernet Variant (DP04QSDD-HK9)

Cisco 400G QSFP-DD High-Power (Bright) Optical Module Ethernet Variant Overview

Cisco 400G QSFP-DD High-Power (Bright) Optical module Ethernet variant is an enhanced version of the currently available QSFP-DD ZR+ Optical Module leveraging the same operational modes but providing as a major enhancement the increase of the Tx Optical Power up to +1dBm (EoL).

Supported client interface for this pluggables is Ethernet based, making this model perfectly suitable to be hosted on a router/switch host. The module asynchronously (GMP) maps an Ethernet signal from a switch/router to an intermediate 400ZR frame structure and then adapts the frame structure to the appropriate FEC engine. The encoded signal is subsequently DSP framed and modulated for transmission as a coherent Dual-Polarity mQAM signal.

Cisco 400G QSFP-DD High-Power (Bright) Optical Module Multirate Ethernet/OTN Variant Overview

The Cisco 400G QSFP-DD High-Power (Bright) Optical module multirate Ethernet/OTN variant shares the same HW platform (and so also the high Tx power) of the Ethernet variant but also supports OTN clients. The module leverages an intermediate ODUFlex,OTUCn/FlexO-x frame structure and then adapts the frame structure with OFEC.

This variant, thanks to the OTN OH, supports Layer-1 (L1) functionality to support authentication and encryption/decryption of the OPU[Cn,4] payload. The security IP provides wire-speed Galois-Counter- Mode (GCM) AES 256-bit security in either authentication-only (GMAC) or encryption/decryption-only (CTR) modes or both (GCM). Inter-host key exchange is supported via communication over the GCC channel.

The Cisco 400G QSFP-DD High-Power (Bright) Optical module multirate Ethernet/OTN module is also offering a PAYG model with a licensed approach in which a 100G BW product is offered (DP04QSDD-LK9).

Features and benefits

In addition to the fact that this solution is providing a high-performance 400G WDM Coherent pluggable perfectly fitting 400G ports from a routing and switching host, additional benefits come from the high Tx power interface. Tx power of +1dBm allows for compatibility with a vast majority of the deployed add/drop scheme of brownfield WDM systems.

In fact, higer TX poweris allowing to be compatible with any high insertion loss add/drop structure. As consequence, differently by the standard OIF MSA optics (limited to -10dBm), the High Tx Power 400G Coherent pluggable can be deployed on the vast majority of existing WDM systems with the only caveat that a 60Gbaud signal is supported.

All network operators can now approach the Routed Optical Networking solution without any limitation driven by the legacy WDM system, as there is no substantial difference from the optical power point of view respect a legacy Coherent Transponder and a new 400G QSFP-DD High-Power (Bright) Optical Module.

The high Tx power functionality is also extremely useful in a P2P application over dark fiber: in this case, the 10dB of additional optical power translates into a much longer reach.

The availability of embedded Tuneable Filter functionality allows the Transmitted Optical Signal to provide a narrow optical spectrum, which allows it to be compatible with any add/drop structure (filtered or unfiltered based) in terms of Tx OSNR penalty.
