Frequently Asked Questions
What is 100GBase-OWDM and how does it differ from standard 100GBase-LR4?
100GBase-OWDM (O-Band Wavelength Division Multiplexing) operates in the O-Band spectrum (1260-1360nm), offering extended reach and reduced latency compared to traditional C-Band systems. The QSFP28 transceiver at 1297.80nm enables higher channel density and cost-effective long-distance fiber deployments over single-mode fiber.
What does DOM (Digital Optical Monitoring) provide?
Digital Optical Monitoring allows real-time monitoring of optical signal strength, laser bias current, module temperature, and supply voltage. This enables proactive network management, early fault detection, and optimized performance tuning for your 100GBase-OWDM infrastructure.
Is this QSFP28 transceiver compatible with my existing network equipment?
Yes. The AddOn module is MSA (Multi-Source Agreement) and TAA (Trade Agreements Act) compliant, ensuring compatibility with standards-based QSFP28 ports on switches, routers, and optical networking equipment from major vendors. Verify your equipment supports O-Band wavelengths and 100GBase-OWDM protocols.
What is the maximum transmission distance for single-mode fiber?
This 100GBase-OWDM QSFP28 transceiver supports up to 20 kilometers of transmission over single-mode fiber, making it suitable for data center interconnects, metropolitan area networks (MANs), and campus backbone applications requiring extended reach without signal regeneration.
