Optowiz has released 10G High-Density CWDM BiDi SFP+. It use half of the CWDM spacing as downlink and the other half as uplink in 2WL HD-SFP. It could double the effective fiber cable capacity by simply replacing old general 1WL SFP+ with the 2WL SFP+ without any additional change in device on the present structure. It will provide simple & low cost solutions for 5G WDM fronthaul and CWDM networks.

The 338 Series Optical Wavelength Meter combines speed and affordability to address the most critical requirements of optical transceiver manufacturers. The wavelength of CW and modulated signals is measured to an accuracy as high as ± 0.3 pm. A measurement rate of 25 Hz results in reduced testing times.
