Introduction:
QSFP (Quad Small Form-factor Pluggable) is a compact, hot-pluggable transceiver module used primarily for high-speed data communication applications. CWDM4 is a specific variant of QSFP that utilizes coarse wavelength division multiplexing (CWDM) technology to achieve high data rates over single-mode fiber.
Design and Functionality:
The QSFP 100G CWDM4 module is designed to provide enhanced performance and reliability in transmitting data at a rate of 100 Gigabits per second (Gbps). It consists of four individual CWDM lasers, each operating at a specific wavelength, which are combined in the module for transmitting and receiving data signals. A key feature of the module is its small form-factor, enabling high-density connectivity in limited rack space.
Transceiver design and components:
The module’s transceiver design incorporates electrical-to-optical and optical-to-electrical conversion components, such as laser drivers, photodetectors, and signal conditioning circuitry. These components ensure efficient conversion and transmission of data over the fiber optic link.
Working principle of CWDM4:
CWDM technology enables the transmission of multiple signals at different wavelengths over a single fiber. In CWDM4, four wavelengths are used to achieve a total data rate of 100Gbps. Each wavelength carries a 25Gbps signal, collectively forming a high-bandwidth data path.
Transmission distance and power budget:
QSFP 100G CWDM4 has a maximum transmission distance of up to 2 kilometers (km) over single-mode fiber. It also offers a power budget that allows for connectivity in diverse network environments, including data centers, metropolitan area networks (MANs), and long-haul networks.
