Introduction
These are Optical Interface Specifications for the most common Network Standards. ANY optical tranceiver that lists itself as compliant with the standard, MUST be able to operate correctly when the power of the optical signal at the receiver is in the range between Receiver Sensitivity and Receiver Saturation. Transceivers by some vendors may perform better; resulting in higher limits for loss and length when using them on both ends of the link.
You may read these specifications as "worst case" values; under these circumstances the Network will work as specified by the Network Standard.
These tabels will grow as we come accross the specification for other interface specifications.
Solution
Permanent Damage
Most receivers will be permanently damaged after exposure to an optical power of 5dBm or more.
