FIBERWDM Dispersion Compensation Module (DCM) is designed to fix the form of optical signals that are deformed by chromatic dispersion.  In case of  SM fiber ,it has dispersion at 1550nm(C-band) . When the 1550nm(C-Band) signal transmit too long distance ,it will lead to high error rate , because of the dispersion influence.   FIBERWDM DCM feature   Dispersion compensation value range is 10-120KM optional. Adapt to standard single mode optical fiber G.652/G655, 1525~1565nm transmission channel. Low insert loss, low polarized mode dispersion. Excellent performance price ratio.  

Fiberwdm Active DWDM system is built from transponders , providing full optical demarcation point agnostic to the routers , switches and ADMs within the network . Fiberwdm Active DWDM offers a way to transport large amounts of data between sites in a data center interconnect setting.The transponder takes the outputs of the SAN or IP switch format , usually in a short wave 850nm or long wave 1310nm format, and converts them through an optical-electrical-optical(OEO) DWDM conversion, in long-haul DWDM networks , several EDFAs are installed sequentially in the line . The number of amplifiers in one section is determined by the fiber cable type , channel count,data transmission rate of each channel,and permissible OSNR value.   Besides ,the maximum transmission distance of the active DWDM system also depends on the influence of chromatic dispersion--the distortion of transmitted signal impulses .When designing a DWDM network project, permissible values of chromatic dispersion for the transceiver should be considered,and ,if necessary,chromatic dispersion compensation modules are included in the line . DCM fixes the form of optical signals that are deformed by chromatic dispersion and compensates for chromatic dispersion in fibers.   Passive DWDM VS. Active DWDM Choosing passive or active DWDM system depends on your requirements and current setup. Because both of them have pros and cons.    

Last time , Fiberwdm factory introduced the dual-fiber solution for optical network transmission . However, not all regions can meet the condition of sufficient fiber. How do we transmit when we only have single one fiber . In the case of single fiber, Fiberwdm factory can provide a RB filter for DWDM single fiber bidirectional transmission. Using RB filter， we can multiplex different wavelengths onto the same fiber. In this way, single-fiber bidirectional transmission is realized.However, there are still many situations encountered in the actual application process. If you have some needs in DWDM  optical network transmission . Share your situation with Fiberwdm factory and complete the optical transmission business together.

Using two-core fiber , Fiberwdm factory can provide a 40CH DWDM optic transmission solution .                       In 10G system , this 40CH DWDM Optic transmission solution , can transmit up to 100 kilometers, and the maximum transmission capacity is 400G.   OBA、OPA are the optic amplifier , we usally call them EDFA , It can help increase the power of light emitted, thereby offsetting the loss of light on the optical fiber line.  

FIBERWDM provide reliable continuous visibility 100% of network traffic to support performance and security with no network performance degradation or disruption.   The design of the FIBERWDM Optical Network Taps is optimized and tested for high-performance fiber networks ranging from 1G to 100G.   FIBERWDM Optical Network Taps are deployed at any inline connection on the network, therefore no additional overhead or management burden is added to the network devices to copy traffic for the monitoring/security infrastructure.   The FIBERWDM Optical Network Taps is compatible with all major manufacturers’ monitoring devices, including protocol analyzers, probes, and intrusion detection systems, and is protocol agnostic.   Application solution as below:      

Celebration that FIBERWDM’s Half active CWDM device and passive CWDM are worked well in 5G  fronthaul system in CMCC. And abtained customer’s approval and favorable.   In 5G fronthaul system, if use optical fiber direct to connect RRU and DDU, it is simple, but it tales up a lot of optical fiber resources, and many times, the optical fiber resources are scare. In this case, if use WDM system, can save your fiber resources.   FIBERWDM are mainly producing WDM products, our 6ch /12ch CWDM, 12CH LMDM, 12ch MWDM are used in 5G fronthaul system.   Application solution as below:         Passive WDM applied in 5G fronthaul system

    In 2017,FiberWDM company completed data collection and analysis projects for the Vietnamese Mobifone in Hanoi and Ho Chi Minh. And won the recognition and appreciation of the partners.  

wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths of laser light. This technique enables bidirectional communications over one strand of fiber, as well as multiplication of capacity.  

In the application of optical fiber communication system, we often encounter a problem, the quality of optical fiber insertion loss is large, which causes the optical module to fail to work or to cause packet loss. So we will use the optical amplifier to amplify the optical signal at this time.
