Coherent optical modules supporting NRZ are produced by companies like Coherent and Link-PP, designed for high-speed, short- to long-reach optical transmission applications.

Overview of NR

Z in Coherent ModulesNRZ (Non-Return-to-Zero) is a simple two-level modulation format commonly used in short- to mid-reach optical links, such as 10G, 25G, and some 100G Ethernet connections.

While NR

Z is cost-effective and straightforward, coherent optical modules typically employ advanced modulation formats like QPSK or QAM for long-haul, high-capacity transmission. However, NRZ remains relevant in certain pluggable and co-packaged optical modules for data center and enterprise applications.

Key Manufacturers and Products

Coherent: Offers 13XX nm photodiode array chips for pluggable transceivers configured for 28 Gbps NRZ or 56 Gbps PAM4. These 1X4 chips feature low dark current, high reliability, and a top-illuminated design suitable for 25G/50G/100G Ethernet applications, single-mode datacom, and telecom deployments. Coherent also demonstrated co-packaged optical engines with 16 channels of 50G NRZ transmitters and receivers for 800G multimode applications, targeting hyperscale data centers and AI/ML clusters.

Link-PP: Provides coherent-compatible optical modules such as QSFP-DD DCO and OSFP DCO, optimized for 400ZR/ZR+ and regional interconnects. While primarily focused on coherent DSP-based modulation, these modules support NRZ in short-reach scenarios and are designed for metro, regional, and hyperscale networks. ApplicationsNRZ-based coherent modules are suitable for: Short- to mid-reach Ethernet links (10G–100G)Data center interconnects where cost and simplicity are prioritizedHyperscale computing clusters requiring low-latency, high-reliability optical linksPluggable and co-packaged optical engines for 25T–50T Ethernet switches Technical ConsiderationsNRZ modules are simpler and consume less power than PAM4 or advanced coherent formats.

Coherent NR

Z modules may integrate with DSPs for error correction and signal processing, especially in hybrid deployments. Form factors include QSFP-DD, OSFP, and co-packaged optical engines, with ongoing development for higher-speed 400G–1. 6T systems.

In summary, Coherent and Link-PP are leading suppliers of NRZ-capable optical modules, offering solutions for both pluggable and co-packaged applications, with a focus on reliability, low power consumption, and integration into modern high-speed networks.

Coherent optical module refers to a typically hot-pluggable coherent optical transceiver that uses coherent modulation (BPSK/QPSK/QAM) rather than amplitude modulation (RZ/NRZ/PAM4) and is typically used in high-bandwidth data communications applications. Optical modules typically have an electrical interface on the side that connects to the inside of the system and an optical interface on the side that connects to the outside world through a fiber optic cable.
