Proline CWDM/DWDM SFP+ transceivers offer a cost-effective solution in long-haul networks by supporting single mode dual fiber applications with CWDM and DWDM wavelengths.
To ensure network equipment compatibility, small form factor pluggable (SFP) is designed to meet Multi-Source Agreement (MSA) standards. By using wavelength-division multiplexing (WDM) technology – a fiber-optic transmission technique that allows different data streams to be sent simultaneously over a single optical fiber network – SFP+ modules can transmit data on discrete & specific wavelengths to improve density on existing fiber.
These two main types of WDM technologies are categorized into coarse (CWDM) and dense (DWDM). CWDM and DWDM are both effective methods to solve the increasing bandwidth capacity of information transmission at present, but they differ from each other in many aspects. The primary difference between the two is the width of each discrete wavelength band. DWDM employs a greater number of narrower wavelength bands (channels) while CWDM utilizes wider ranges per brand.
