The transceiver's ability to support 40G data rates over long distances with low power consumption is critical for modern fiber-optic networks.

Understanding Single-Mode Fiber and the Role of 1310 nm Wavelength

Single-Mode Fiber (SMF)

Single-mode fiber (SMF) is designed to carry light signals over long distances with minimal loss. Unlike multimode fiber (MMF), which uses larger core diameters and supports multiple light paths, single-mode fiber allows a single light path to propagate, minimizing signal dispersion and ensuring long-distance signal integrity. The 40G-QSFP-ER4 module leverages the superior capabilities of SMF, enabling high-speed data transmission at a distance of up to 40 km, which is crucial for long-range networking in large-scale infrastructures.

The 1310 nm Wavelength

At the heart of the 40G-QSFP-ER4 module's efficiency is its use of the 1310 nm wavelength. This wavelength is ideal for long-range data transmission over single-mode fiber because it experiences less attenuation and dispersion than other wavelengths like 850 nm or 1550 nm. The 1310 nm wavelength ensures that signals travel with minimal distortion, maintaining the integrity of the data over extended distances. Additionally, the 1310 nm wavelength is widely supported by existing fiber-optic infrastructure, making it an ideal choice for modern optical communication systems.
