1. Pre-terminated Fiber Cabling (1) Overview Sun Telecom’s MPO/MTP solution is pre-terminated solution which means it can easily expand or relocate systems without relocating patch cords and cassette. Therefore it can be applied to maintenance of currently operating solution to respond flexibility to the customers who consider physical configuration, space-efficiency and future scalability. By providing pre-terminated product in the factory, Sun Telecom’s MPO/MTP solution can guarantee high performance & long link length as a result of enhanced insertion loss and decrease of resistance. Also it can reduce human effort when terminating on site with no needs of special tools to terminate optical cables. (2) Features •  High-density connection with multi-core (up to 24-core) support •  Class OF-300 channel support •  Push-pull type connecting for easy & fast installation •  40/100Gbps parallel transmission (IEEE 802.3ba) support ...

CWDM VS. DWDM

图片
Coarse wavelength division multiplexing (CWDM) and dense wavelength division multiplexing (DWDM) are used for increasing the bandwidth of fiber by combining optical signals of different wavelengths on one strand of fiber. This article will discuss the differences between CWDM and DWDM. CWDM and DWDM are both effective solutions to solve the increasing bandwidth capacity of information transmission. But they differ from each other in many aspects. The below parts will discuss some differences between CWDM and DWDM. 1)Channel Spacing The channel spacing is the nominal difference in frequency or wavelength between two adjacent optical channels. CWDM has a wider channel spacing than DWDM. CWDM can transport 18 wavelengths with a channel spacing of 20nm in the spectrum grid from 1470 nm to 1610 nm. On the other hand, DWDM can carry 40, 80, 96, or up to 160 wavelengths with a narrower spacing of 0.8/0.4nm (100 GHz/50 GHz grid). Its wavelengths are from 1525nm to 1565nm (C band) and 15...
