High-speed optical connector NRZ available now
High-speed NRZ optical connectors are available today with data rates from 25Gbps to 56Gbps per channel, supporting multi-mode and single-mode fiber for data center, HPC, and AI applications.
Available NRZ Optical Transceivers and Connectors
1. Amphenol LEAP On-Board Transceiver
- 12-channel duplex optical transceiver
- Up to 25Gbps per channel (300Gbps cumulative) on multi-mode fiber
- Qualified to Telcordia standards and in production since 2016
- Designed for datacenters, supercomputers, and 5G broadband applications
- Supports non-standard protocols in this data rate range 2. NVIDIA Mellanox LinkX InfiniBand Transceivers
- Single-mode 1310nm wavelength transceivers available in NRZ and PAM4
- NRZ options support 10G/25G per channel for short to medium reaches (up to 500m for PSM4, 2km for CWDM4/FR4, 10km for LR4)
- Compatible with QSFP+, QSFP28, QSFP56, and OSFP form factors
- Extensively tested for low bit-error-rate and high reliability in GPU-accelerated AI systems 3. Samtec High-Speed Board-to-Board Connectors
- NovaRay® Extreme Performance (EP) and AcceleRate® High-Performance (HP) arrays
- Rated for 56Gbps NRZ applications
- Pitch options: 0.80mm and 0.635mm
- Suitable for 5G networking, industrial, aerospace, AI/ML, automotive, and instrumentation
- Designed for tight impedance control and high signal integrity 4. Molex QSFP Connector System
- Supports 28G NRZ, 56G PAM4, 112G PAM4, up to 400Gbps aggregate
- Low insertion loss, low crosstalk, and EMI containment
- Thermal management options for high-power plugs (up to 5W)
- Ideal for server farms and high-bandwidth wireless infrastructure 5. Amphenol Aerospace QEPT Series
- QEPT 100G NRZ module supports 25Gbps NRZ backward compatibility
- QEPT 200G PAM4 modules are backward compatible with NRZ
- Compact design with excellent heat dissipation for space-constrained applications
- Supports 850nm multi-mode fiber and scalable channel configurations
Key Considerations
- Data Rate: NRZ connectors typically support 25–56Gbps per channel; PAM4 is used for higher aggregate rates.
- Fiber Type: Multi-mode for short-reach (<500m), single-mode for longer distances (up to 10km).
- Form Factor: QSFP, OSFP, and board-to-board arrays are common.
- Applications: Data centers, HPC clusters, AI/ML systems, 5G infrastructure, and industrial or aerospace environments.
- Thermal Management: High-speed NRZ connectors may require heat sinks or airflow optimization for reliable operation. These products are commercially available now and widely used in high-performance networking and computing environments, providing reliable NRZ signaling for both short and long-reach optical links.
