From both technical and economic perspectives, the ability to provide potentially unlimited transmission capacity is the most obvious advantage of DWDM technology. The current investment in fiber plant can not only be preserved, but optimized by a factor of at least 32. As demands change, more capacity can be added, either by simple equipment upgrades… Continue reading Why DWDM?
Simply put, RAN is the base station, which is the network. Before the advent of the 5G era, the base station (RAN) consisted of three parts: the antenna, the RRU (radio-frequency pull-out unit), and the BBU (baseband processing unit). RRU is used to transmit and receive signals, while BBU is used to process signaling messages.… Continue reading What are D-RAN, X-RAN, C-RAN and O-RAN? What’s the relationship between them?
What is an MTP/MPO-LC branch jumper? A branch jumper is a fiber optic component with a multi-core MTP/MPO connector at one end and an outer sheath branch with a single or double core LC connector at the other end. It provides a conversion for the MTP/MPO connector for the trunk cable, trunk extension cable or… Continue reading How does the switch select the correct branch jumper?

WDM technology has many advantages and is developing rapidly. Main features include: 1)The bandwidth resources of the optical fiber can be used to increase the transmission capacity of an optical fiber several times to several tens of times compared with single-wavelength transmission; 2) multi-wavelength multiplexing in single-mode optical fiber transmission can save a lot of optical fiber… Continue reading DWDM/OTN Application Scenario
OLP-Optical Line Protection is a product that is used in the protection of network transmission line,the product can realize optical power monitoring and automatic switching. In optical communication network, OLP real-time monitoring optical power of working optical fiber and standby optical fiber. When the optical power value of working optical fiber is below the set… Continue reading What is OLP in DWDM ( Optical Line Protection) ?
The WDM Transponder(OEO) is widely used in many networks, and the most classical function is wavelength conversion. When adding a CWDM/DWDM Mux to the WDM network, there is a requirement to convert the optical wavelengths like 850nm, 1310nm and 1550nm to corresponding CWDM/DWDM wavelengths. Then the WDM Transponder comes to assist,it can convert incoming optical… Continue reading What is the main function of the WDM Transponder (OEO)?
Is it possible to add EDFA and DCM modules in CWDM system? No, EDFA and DCM modules can not be used in CWDM system. Since the EDFA and DCM modules‘ operating wavelength range is C- Band (1528~1564nm) which can not cover all the CWDM operating wavelength. Generally, the amplifier is used for DWDM systems.
