Key Characteristics of CWDM Laser Diode
Working Window
CWDM mainly operates in the optical fiber low-loss window of 1270nm-1610nm, covering the O -band (1260-1360nm), E-band (1360-1460nm), S-band (1460-1530nm), C-band (1530-1565nm) and L-band (1565-1625nm).
Channel Count
Due to the wide wavelength spacing and limitations of optical fiber loss and device characteristics, the maximum number of channels in a CWDM laser diode is usually 16 ( some simplified systems can support 8 or 4 channels).
Transmission Distance
The transmission distance of CWDM laser diode is relatively limited, typically 20-80 kilometers (without repeaters). Extending the distance can be achieved by adding optical amplifiers or dispersion compensation modules, but this increases costs.
Data Input
Data from various sources like Ethernet is fed into the CWDM system.
01
Wavelength Multiplexing
The data is then converted into optical signals using lasers with different wavelengths. These wavelengths are spaced apart to avoid interference.
02
Transmission
The multiplexed optical signals are then combined and transmitted over a single fiber optic cable.
03
Demultiplexing
At the receiving end, the signals are separated based on their wavelengths using a demultiplexer.
04
Data Output
Finally, the separated signals are converted back into electrical signals and delivered to their respective destinations.
05
Metropolitan Area Networks (MANs) and Access Networks
● Applicable to the interconnection between various computer rooms and base stations in the city, and transmission of data, voice and other comprehensive services;
● Supports the expansion of backbone links of enterprise networks and campus networks to meet the needs of multi-service aggregation.
Data Center Interconnect (DCI)
● Connect different data centers over short distances (e.g., 10-40 kilometers) to achieve high-speed data transmission between servers and storage devices;
● Supports multiplexing transmission of multiple protocol signals such as Ethernet (10G/40G/100G) and FC (Fibre Channel).
Cable Television (CATV) Networks
● It is used for the transmission and distribution of broadcasting and television signals, while carrying video, broadband and other services, improving the utilization rate of optical fibers.
Industrial Control and Monitoring
● In scenarios such as industrial parks and transportation hubs, long-distance transmission of surveillance videos and control signals is achieved, simplifying wiring.
