What is 100G CWDM4 QSFP28?

Let’s analyse the acronym and language that describe 100G CWDM4 QSFP28 technology in high-speed data transmission.

100 gigabit or 100 G: This denotes the data rate, which is astoundingly high at 100 gigabits per second (Gbps). In other words, it can send 100 billion bits of data every second.

CWDM4 is a four-channel coarse wavelength division multiplexing system. Multiple data streams can be delivered over a single optical cable utilising distinct wavelengths of light for each stream in CWDM. The “4” indicates that four unique channels or wavelengths are used.

QSFP28 is an abbreviation for Quad Small Form-Factor Pluggable 28, which describes the physical form factor and interface type. Because QSFP28 modules are small and hot-swappable, they are ideal for high-density network deployments.

100G CWDM4 QSFP28 is a technique that uses four unique wavelengths of light to carry data at a blistering 100 Gbps, all while being encased in a tiny, standardised form factor.

Underlying Technology and Principles

To accomplish high-speed data transmission, 100G CWDM4 QSFP28 technology is based on the principles of wavelength division multiplexing (WDM). This is how it works:

Coarse Wavelength Division Multiplexing (CWDM): CWDM is a method of assigning various data streams to different wavelengths of light in the optical spectrum. In the case of CWDM4, four distinct wavelengths are employed to simultaneously transmit four distinct data channels.

CWDM Multiplexing & Demultiplexing

The Quad Small Form-Factor Pluggable (QSFP28) form factor is intended for high-speed data transfer. It has four transmission channels and four reception channels, which correspond to the four Coarse Wavelength Division Multiplexing wavelengths.

Optical Transceivers: Optical transceivers are built inside the QSFP28 module and transform electrical data signals into optical signals and vice versa. These transceivers are highly designed to operate at the Coarse Wavelength Division Multiplexing wavelengths.

Multiplexing and demultiplexing devices guarantee that the four wavelengths are mixed for transmission and separated for reception at both ends of the transmission.

Data is transferred through ordinary single-mode optical fibres, which are capable of transmitting high-speed communications across great distances with low signal loss.
