- If I put too much power into the OWM, will I damage the device?
No, the OWM cannot be damaged, however, it will saturate the detector and will notify the user
Back to top
- How many levels of security access are available on the OWM?
There are 4 levels of security
Back to top
- How many software images can be loaded on the OWM at one time?
The OWM can have up to 3 software images loaded at one time, while only one software image can be active. The GUI can be used to toggle between different software images

- What type of network management support is available on the OWM?
SNMP v1/v2 agent and MIB, with a JAVA based GUI application.

- What is the switch time between optical ports on the OWM?
The optical switch toggles between ports every 30 seconds on a 2 port (will be 3 sec in near future) to 1 sec on an 8 port OWM
Back to top
- How many fibers can the OWM monitor, and how is this accomplished?
The OWM includes an optical switch which allows up to 8 fibers to be monitored, 1 fiber at a time. Each fiber can be monitored automatically or manually

- What is the MTBF of the OWM?
The MTBF of the OWM is 20 years.
Back to top
- How often does the OWM need to be calibrated?
This product does not require cyclical calibration service, and existing units may be labeled with a No Calibration Required (NCR) Sticker.
Back to top
- What is the dynamic range of the OWM?
The OWM dynamic range is 60dB with an absolute noise floor of –70 dB
Back to top
- What is the wavelength accuracy of the OWM?
The OWM wavelength accuracy is +/- 0.02nm
Back to top
- What type of power is required for the OWM?
The OWM uses –48Vdc power but comes compete with an AC adapter.
Back to top
- What are the power requirements for the OWM?
Less than 10 Watts
Back to top
- What tap power is required for the OWM to operate and how do you work with different optical tap powers on different devices?
The OWM is non-intrusive, where it only requires as little as 0.5% of the light on a given fiber to make its measurements. Given that DWDM devices have different optical tap values, the OWM can be configured through the GUI (graphical user interface) to accommodate any optical tap value from 0.5% to 100% (e.g. plugging directly into a laser).
Back to top
- What technology does the OWM employ?
The OWM is based on a patented diffraction grating technology that uses an InGaAs Detector Array to rapidly detect power, wavelength and OSNR (Optical Signal to Noise Ratio)
