  • Product Description

    QSFP28-100G-ER4 Lite is a medium-reach optical transceiver module for high-speed data networks, adopting the QSFP28 form factor to deliver 100 Gbps (100GbE) via four parallel 25 Gbps lanes. Operating with LWDM wavelengths over single-mode fiber (SMF) with a Dual LC connector, it supports transmission distances up to 30km. Featuring high density and low power consumption, it is widely used in long-distance data center interconnections, metropolitan area networking, and telecommunications transmission scenarios.QSFP optical transceiver module provides a compact and efficient solution for high-speed data transmission in data centers, telecom networks, enterprise systems and other demanding communication environments. Designed for pluggable deployment, it enables electrical-to-optical and optical-to-electrical signal conversion while supporting high-density network connections.

    With compact dimensions, flexible application options and compatibility with suitable switches, routers and fiber-optic systems, the module helps network operators optimize rack space and simplify connectivity. Different specifications can support various transmission rates, wavelengths, fiber types and link distances, allowing customers to select solutions according to their actual network architecture.

    For data centers and system integrators, stable optical connectivity is essential for handling growing data traffic. QSFP modules can help reduce connectivity complexity, facilitate maintenance and provide a scalable path for network upgrades. Customers can select the appropriate model according to equipment compatibility, transmission distance, optical parameters and operating conditions, creating a reliable foundation for high-performance networking.
