Cisco DP04QSDD-HK9= Transceiver Modules

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.
