ADVANCED FEATURES:

High-Bandwidth Parallel Optical Design :

The GOXQ28-85100G-SR4 transceiver delivers full 100 Gbps throughput using 4 × 25 Gbps parallel lanes, enabling simultaneous high-speed transmission and reception across all channels. This parallel optical architecture minimizes congestion and reduces latency, ensuring reliable short-range connectivity for multi-lane interconnects. It also optimizes fiber infrastructure utilization, making it ideal for dense server-to-switch links, top-of-rack connections, and high-capacity data centre deployments.

Integrated Clock and Data Recovery (CDR) :

Internal CDR circuits on both transmitter and receiver channels maintain precise signal timing, reduce jitter, and preserve signal integrity even in densely populated optical environments. This ensures consistent, error-free data transmission for critical applications such as virtualization, storage replication, high-performance computing, and enterprise backbone networks, maintaining optimal performance under heavy traffic conditions.

Digital Diagnostic Monitoring (DDM) :

The built-in DDM function provides real-time monitoring of module parameters including temperature, supply voltage, transmit/receive optical power, and overall module health. By providing this visibility, network operators can proactively detect and resolve potential issues, plan maintenance effectively, and minimize network downtime. This feature is essential for maintaining reliability and operational efficiency in short-reach, high-density interconnects.

Hot-Pluggable QSFP28 Form Factor :

The compact QSFP28 module supports hot-swapping, allowing installation, replacement, or upgrades without interrupting ongoing network operations. This feature simplifies deployment and maintenance, enabling fast provisioning and minimizing disruption in enterprise, cloud, and HPC environments where uptime and scalability are critical.

Low Power Consumption and Thermal Efficiency :

With typical power consumption under 3.0 W, the module maintains minimal heat output while delivering stable optical performance. Its energy-efficient design improves thermal management within high-density switch chassis and server NICs, enhancing reliability, reducing cooling costs, and ensuring longevity during continuous operation in demanding environments.

High-Density Data-Centre Compatibility :

Optimized for leaf-spine, core, and aggregation network architectures, the module supports seamless integration with major 100G Ethernet switches and NICs across multiple vendors. This ensures high interoperability in mixed environments and makes the transceiver suitable for enterprise networks, cloud infrastructure, and high-performance computing clusters, providing consistent and scalable performance.
