Description
The AddOn QSFP28-100GB-ER4L-I-AO is a high-performance 100GBase-ER4L QSFP28 transceiver designed for long-reach 100 Gigabit Ethernet applications over single-mode fiber (SMF). Supporting transmission distances of up to 40 km with wavelengths ranging from 1295nm to 1309nm, this transceiver features a duplex LC connector, digital optical monitoring (DOM), and operates in industrial temperature environments from -40°C to 85°C. Built to MSA standards and fully compliant with TAA requirements, it ensures seamless integration into existing network infrastructures. Each unit undergoes rigorous testing for performance, serialization, and reliability, offering exceptional ESD protection, low EMI, and a limited lifetime warranty — making it ideal for access, enterprise, and data center deployments.
