 Simplify Your 100G Transport: The Power of Coherent QSFP28 Pluggables

The demand for 100G connectivity beyond the data center is exploding. Whether for connecting data centers, building metro rings, or upgrading 5G backhaul, traditional solutions involving separate, bulky transponders are costly, complex, and power-hungry. Now, you can break free. Optech's 100G QSFP28 Coherent modules integrate advanced coherent optics into a standard, hot-swappable QSFP28 form factor, revolutionizing long-haul and metro network design.

What is 100G Coherent Technology?

Unlike traditional direct detect optics, coherent technology is the gold standard for long-distance transmission. It uses techniques like Dual-Polarization Quadrature Phase Shift Keying (DP-QPSK) modulation and sophisticated Digital Signal Processing (DSP). This allows it to encode more data onto a single laser wavelength, simultaneously combating physical fiber impairments like chromatic dispersion and polarization mode distortion. The result is robust, high-capacity links over incredible distances.

The QSFP28 Form Factor Revolution

The true innovation lies in the packaging. By embedding this powerful coherent engine into a standard QSFP28 form factor, we have eliminated the need for proprietary, chassis-based transponders. This brings the benefits of coherent technology—once reserved for large telecom carriers—to a much broader market, including cloud providers, enterprises, and cable operators.

Key Technical Advantages of Optech's 100G QSFP28 Coherent

• Extended Reach without EDFAs: Our modules are engineered to achieve links of up to 1000 km and beyond using standard single-mode fiber (G.652), making them ideal for regional and long-haul DCI applications.

• High Spectral Efficiency with DWDM: Seamlessly integrate into existing Dense Wavelength Division Multiplexing (DWDM) systems. Maximize the capacity of your fiber plant by transmitting multiple 100G channels on different wavelengths.

• Built-In Performance Monitoring: The integrated DSP provides real-time monitoring of key parameters like Optical Signal-to-Noise Ratio (OSNR), Chromatic Dispersion (CD), and Polarization Mode Dispersion (PMD). This enables proactive network maintenance and quick fault isolation.

• Low Power Consumption: Designed for efficiency, our modules typically consume less than 7W, allowing for high-density deployments in modern switches and routers without overheating.

Target Applications & Use Cases

• Data Center Interconnect (DCI): Create simple, high-capacity, and cost-optimized links between data centers over distances from 80km to 1000km.

• Metro and Regional Transport Networks: Simplify metro aggregation and regional transport rings, replacing complex legacy systems with a pluggable, router-centric approach.

• 5G Midhaul and Backhaul: Deliver the high bandwidth and robust performance required for 5G network infrastructure, connecting cell sites to core networks.

• Cable Operator Infrastructure: Upgrade and expand the core network for cable multiple-system operators (MSOs) to support growing video and broadband data demands.

Optech 100G QSFP28 Coherent vs. Traditional Solutions

Why struggle with a stack of discrete components? Our pluggable solution dramatically reduces:

• Cost: Lower CapEx (no standalone transponder) and OpEx.

• Complexity: Plug directly into a compatible switch or router port—no additional equipment needed.

• Footprint: Save valuable rack space and power.

Conclusion: Future-Proof Your Network with Coherent Pluggables

The era of bulky, proprietary transport hardware is over. By adopting Optech's 100G QSFP28 Coherent technology, you are not just solving today's capacity challenges—you are investing in a simpler, more agile, and cost-effective network architecture for the future.
