The 100Gbps QSFP28 EZR4 Optical Transceiver is designed for ultra-long-distance optical communication, enabling 100G Ethernet transmission over single-mode fiber (SMF) with a reach of up to 100 kilometers. This high-performance module supports 100GBASE-EZR4 with a line rate of 103.125Gbps and OTU4 with a line rate of 111.81Gbps, making it ideal for long-haul networking, metro networks, and high-capacity backbone systems.

The transceiver incorporates a LAN WDM EML (Electro-Absorption Modulated Laser) and a PIN receiver with SOA (Semiconductor Optical Amplifier) to enhance signal integrity and transmission performance over extended distances. Featuring a 4-lane MUX/DEMUX architecture, it delivers an aggregate bandwidth exceeding 100Gbps, ensuring seamless data flow and reduced signal degradation. It is fully compliant with IEEE 802.3-2012 Clause 88 and ITU-T G.959.1 standards, guaranteeing interoperability with major networking infrastructure.

Designed for easy deployment, the QSFP28 ZR4 transceiver features duplex LC connectors, allowing for straightforward integration with existing fiber optic networks. It supports Forward Error Correction (FEC), significantly improving data transmission reliability by reducing bit errors and optimizing signal recovery over long distances.

Operating on a single +3.3V power supply, the module has a maximum power dissipation of 6.5W, making it energy-efficient for long-haul and metro network applications. It is designed for commercial operating environments with a temperature range of 0°C to 70°C, ensuring consistent performance in varying conditions.

Equipped with advanced digital diagnostic monitoring (DDM) via a 2-wire serial interface, the transceiver provides real-time access to critical performance parameters, including temperature, voltage, bias current, and optical power levels, allowing for proactive network maintenance and increased operational efficiency.

The QSFP28 ZR4 is RoHS compliant, adhering to strict environmental and safety regulations. Integrated built-in safety features protect against optical signal degradation and hardware failures, ensuring a dependable solution for long-distance optical communication in data centers, carrier networks, and high-capacity backbone systems.

All our transceiver products are covered with a lifetime warranty.
