N CH CWDM Mux Demux Module
CWDM is a low-cost WDM transmission technology for MAN Network, which uses the huge bandwidth of single-mode fiber in low-loss region to couple different wavelengths of light to one fiber for transmission. The protocol and rate of cwdm are transparent and support 1G/10G Ethernet, SDH/SONET and 8/4/2/1g fiber channel on the same fiber link.OPTICO offers WDM products with a very high level of protection, not only using high-quality shell materials, rust-proof and wear-resistant, and the product itself conforms to industry standards, with very good stability and reliability, low insertion loss and excellent channel isolation. At present, CWDM technology has been widely used in telecommunication, broadcasting, enterprise network, campus network and so on.

Highlight

Low insertion loss

High channel isolation

Based on free space technology
Project Case
CWDM is an attractive solution for carriers who need to upgrade their networks to accommodate current or future traffic needs while minimizing the use of valuable fiber strands. The escalated demands for bandwidth and capacity are driving networks to look for agile, cost-effective data optical transport solutions.
Project Quirement:
• Networking Modes: Point-to point • Transmission Distance: 15km
• Transmission Capacity: 18x 10G
• Fiber Link Loss: 6dB (0.4dB/km)
• Fiber Type: G.652D

Different transmission methods

WDM single fiber bidirectional transmission

WDM dual-fiber bidirectional transmission
OPTICO WDM Production
As we've said countless times, CWDM is now the equivalent of the PLC Splitters of a decade or so ago, when FTTH networks began to emerge, just as 5G MAN networks are emerging today. As the largest manufacturer of PLC Splitter in Shenzhen, we also set up four WDM lines in 2018, covering an area of more than 2000 square meters with a monthly WDM capacity of up to 200000 channels.
These years our CWDM, due to the precipitation of technology and mature communist process, our cost control capacity also reached the peak, so this period of CWDM is not only cost-effective, and rapid delivery.
