Our pluggable coherent modules are used across our optical network platforms, converged IP-optical routing and fixed network access solutions. They can also be deployed in third-party and white box switches and routers to provide market-leading integrated coherent transport solutions. Supporting a wide range of interoperability standards and implementation agreements, our coherent pluggable optics also offer unique operating modes for even greater performance.
Pluggable coherent optic transceivers integrate all the functions needed in a digital coherent optic (DCO), including the coherent digital signal processor (DSP), the optics needed for light transmission, modulation and detection, and the microprocessor electronics for turn-up and operation. All these functions are contained in a highly integrated, industry-standard small form-factor transceiver, including SFP form factors that enable pluggability into existing router and switch ports. They avoid the density penalties typical of short-reach client “grey” optics.
Our pluggable coherent optical modules support a variety of data rates, including 100Gb/s, 400Gb/s and 800Gb/s to enable application optimization based on capacity, distance and port type.
100G Pluggable DCO Transceivers
The QDCO1 extends the performance of coherent optics to metro, access and edge applications. The QDCO1 operates at 28Gbaud and supports 100Gb/s tunable WDM transmission in the compact and popular QSFP28 pluggable form-factor, with low power consumption of <6Watts and support for 100GE and OTN clients.
Supporting single-span unamplified reach of up to 80km, amplified reach up to 120km, and multi-span amplified reach of up to 300km, the QDCO1 can be used in a wide range of transport, router, PON, radio and broadband access platforms.

100G ZR Coherent Module
400G Multihaul
Our 400G Multihaul pluggable DCO transceivers support high optical output launch power of +3dBm to enable use across ROADM-enabled networks for maximum network efficiency. Variable baud rate operation and QPSK, 8QAM, and 16QAM modulation enable operation at 100G, 200G, 300G and 400G per wavelength.
This allows for flexible and efficient network scaling, from 100G over thousands of kilometers, to 400G per wavelength over several hundreds of kilometers and through multiple ROADM nodes. Low power consumption and support for both Ethernet and OTN clients and framing, provides the flexibility to operate in optical transport systems, router platforms, and other third-party systems.

400ZR/ZR+ Coherent Modules
400G Pluggable DCO Transceivers
Our 400G pluggable DCOs are powered by the PSE-V Compact (PSE-Vc), part of the PSE-V family of coherent optics.
The PSE-Vc supports operation at a variety of baud rates from 30 to 69GBaud. It is an ideal choice for scaling network capacity in access, metro aggregation and metro-regional core networks.
400ZR
The QDDCO4Z provides multi-vendor interoperability based on the OIF 400ZR specification, in a QSFP-DD form factor compatible with 400GE ports. Using C-FEC and 16QAM modulation, the QDDCO4Z supports 400G tunable WDM transmission per wavelength, with single-channel unamplified reach up to 40km, and amplified multi-channel operation up to 120km.
The QDDCO4Z is the ideal choice for single-span metro connections for data center interconnection (DCI), business service connections, and backhaul of radio, PON or other broadband service traffic at 400G speeds.
400ZR+
The QDDCO4 provides increased performance and flexibility compared to the 400ZR module and also comes in a QSFP-DD form factor. The module supports the OpenZR+ Open FEC (o-FEC) standard. It supports a range of baud rates and modulations including QPSK, 8QAM, and 16QAM, which enables operation at 100G, 200G, 300G and 400G over a single wavelength, across hundreds to thousands of kilometers.
The QDDCO4 extends the reach of 400ZR modules to support multi-span connections over greater distances and through limited intermediate ROADM pass-throughs.
Our 400G Multihaul pluggable DCOs, available in both QSFP-DD and CFP2 pluggable form factors, are an ideal choice for scaling network capacity across a wide range of use cases in access, metro aggregation, and metro-regional core networks, where higher performance is needed compared to 400ZR/ZR+ DCOs.
The C2DCO4 and C2DCO4O are implemented in the CFP2 form factor, while the QDDCO4H is implemented in the QSFP-DD form-factor for use on both transport and router platforms.
The C2DCO4 supports a Nokia FEC mode for greater performance and provides interoperability with our PSE-2, PSE-3 and PSE-V coherent optics. The C2DCO4O provides interoperability with OIF 400ZR and OpenROADM industry standards, while the QDDCO4H provides interoperability with OIF 400ZR and 400G OpenZR+ standards.
