Why Buy Used?
The compelling argument for considering second user equipment can be summed up in three areas: cost, speed of delivery and availability.
Used equipment costs anything from 20-80% less than the equivalent new, can be delivered within days rather than weeks.
Additionally, second user equipment is more reliable. Out of box failure rates for new/sealed equipment can range from 2-5%. Second user equipment is more reliable, in the fraction of a percent range, as any factory faults would have been exposed in first use.

Digital Diagnostics Monitoring
Inveho optical SFP transceivers support standard digital diagnostics monitoring (DDM) functions where applicable (this feature is also known as digital optical monitoring, DOM). Modules with this capability give the end user the ability to monitor operational parameters of the SFP, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage, in real time. This functionality is commonly implemented for monitoring on routers, switches and optical transport equipment via SNMP.
