Mature production process
Free space technology
Low loss
High channel isolation and low crosstalk
Can real reach industrial Grade
The higher isolation value enables CWDM devices to perform sufficient signal isolation during multi-signal transmission in a wavelength division multiplexing system, effectively preventing crosstalk between signals from causing transmission signal distortion 3 port CWDM device produced by OPTICO has a mature production process.
CATV Network
Enterprise Network
5G Connectivty
The lower insertion loss enables CWDM devices to have lower signal attenuation when used in wavelength division multiplexing systems, thereby reducing the power requirements of the signal transmitter
The optical path is made by non-glue and semi-automatic packaging. The performance is stable and reliable. It can work in harsh environments from -40°C to +85°C to ensure stable signal transmission
The production information management system independently developed by OPTICO has a complete electronic process for each product to ensure the quality reliability and traceability of the device
CE
ISO
ROHS
3 port CWDM devices provided by OPTICO comply with RoHS, meet Telcordia GR-1209-CORE and GR-1221-CORE, and also meet the industry's 168-hour PCT reliability test.
