As artificial intelligence (AI), machine learning (ML) training clusters, high-performance computing (HPC), and 5G telecommunication networks demand unprecedented bandwidth, the migration of physical layer interconnects from legacy speeds to high-density 100G, 200G, and 400G form factors has transitioned from an upgrade strategy to an operational necessity.
Utilizing 4x25G NRZ electrical lanes, QSFP28 remains the backbone of modern enterprise switching. Supporting architectures like SR4, LR4, CWDM4, and PSM4, it balances cost, power efficiency, and long-term deployment reliability.
Stepping stone using PAM4 (4-level Pulse Amplitude Modulation) technology. By transmitting 2 bits per symbol on 4x50G lanes, QSFP56 doubles bandwidth efficiency over QSFP28 without scaling up physical fiber pathways.
Leverages 8x50G PAM4 or 4x100G PAM4 technologies. Designed to resolve the extreme density bottlenecks of AI engines, incorporating complex digital signal processors (DSP) to handle dispersion over distances from 100m up to 80km.

Zyqora operates a advanced 386-square-meter manufacturing facility dedicated to cleanroom optical assembly, precise alignment, laser welding, and automated component-level performance analysis. With 8 years of export trade experience and 10 years of deep industry expertise, Zyqora has successfully developed a footprint spanning North America, Western Europe, the Middle East, Southeast Asia, and Latin America, yielding an annual export trade volume exceeding USD 18 million.
Quality assurance is the absolute foundation of our operations. Supported by 42 specialized Quality Control (QC) engineers, every single module undergoes rigorous optical-electrical testing, sweep-aging under extreme temperature zones, real-switch platform compatibility validation, and bit error rate (BER) checks to ensure compliance with MSA (Multi-Source Agreement) requirements.
The optical transceiver manufacturing cluster in China provides a significant advantage in engineering turnaround times, high-density component sourcing, and raw cost efficiencies that direct manufacturers in other regions struggle to match. By leveraging this integrated manufacturing ecosystem, Zyqora delivers high-end optical transceivers with unmatched speed-to-market and strict cost controls.
From micro-optics, TOSA/ROSA sub-assemblies, and specialized laser diodes (EML, DML, VCSEL) to state-of-the-art semiconductor substrate boards and specialized metal housings, our factory capitalizes on raw materials and components sourced directly from a network of over 860 regional partners. This density of suppliers drastically minimizes turnaround and assembly times for custom configurations.
Proximity to component fabs allows us to build, test, and adapt customized physical layer prototypes within days instead of weeks, accelerating system deployments.
Utilizing high-end automated die attach and precision optical alignment machines to assure sub-micron alignment accuracy across multi-lane PAM4 transmitter modules.
Continuous process optimization minimizes material scrap rates, allowing us to maintain stable pricing even amid global chip supply fluctuations.

Modern data center network layouts often utilize a mix of hardware from different vendors. Deploying optical links in Cisco, Juniper, Arista, Dell, or Mellanox switch architectures requires transceivers programmed with exact, vendor-specific firmware signatures to bypass port lockout codes and ensure proper link state communication.
At Zyqora, our 65 R&D design engineers specialize in advanced firmware tuning, EEPROM writing, and multi-platform validation. Our custom OEM/ODM services cover custom labeling, specific packaging layouts, customized register tables, and diagnostic parameter tuning to guarantee seamless interoperability right out of the box.
Last year alone, Zyqora engineered and deployed 168 new product variations. This includes specialized transceivers featuring customized thresholds for digital diagnostic monitoring (DDM), enabling network administrators to monitor parameters like TX/RX power, internal temperature, and bias current in real-time across various network monitoring platforms.

NRZ (Non-Return-to-Zero) uses two voltage levels to represent 1s and 0s, sending 1 bit per clock cycle. This is standard in 10G, 25G, and legacy 100G (4x25G lanes) setups. However, scaling NRZ to higher speeds introduces high high-frequency attenuation. PAM4 (Pulse Amplitude Modulation 4-Level) utilizes four signal levels to transmit 2 bits per clock cycle, doubling the data rate over the same physical bandwidth. PAM4 is essential for 50G-per-lane systems, making it the standard technology for 200G (4x50G) and 400G (8x50G or 4x100G) transceivers.
No. Zyqora transceivers are programmed with host-specific EEPROM signature configurations designed for exact compatibility with Cisco, Arista, Juniper, Dell, HPE, Mellanox, and other manufacturers. Our testing facility contains switch racks from these brands to perform rigorous validation testing before shipment. This ensures that when our transceivers are plugged in, they are recognized as native modules without requiring CLI warning bypass commands.
These suffixes specify reach and fiber requirements:
• SR4 (Short Range): Uses 4 lanes of multimode fiber (MMF) over 850nm up to 100m, typically utilizing MPO connectors.
• DR4 (Datacenter Range): Uses 4 lanes of single-mode fiber (SMF) over 1310nm up to 500m.
• FR4 (Far Range): Multiplexes 4 lanes onto a single duplex SMF line using CWDM over 2km.
• LR4 (Long Range): Designed for 10km transmission over single-mode fiber using duplex LC connections.
400G transceivers generate significant heat (up to 12W per port) due to high-speed DSP processing. We use custom zinc-alloy die-cast housings with high-conductivity thermal pads to maximize heat dissipation. Furthermore, every batch undergoes thermal cycle chamber aging tests from -40°C to +85°C to ensure the laser diodes maintain precise wavelength stability under extreme operating temperatures.
Our customization services include laser-engraved custom labels, serialized tracking codes, customized EEPROM firmware coding for specific host systems, custom DDM threshold settings, and retail/bulk packaging. Zyqora's engineering team can also modify hardware properties to meet specific thermal and electrical requirements.
