Transceiver Optical Interface Specifications

Introduction

These are the most common Optical Interface Specifications for the most common Network Standards.  Some transceivers may perform better which will result in a higher loss tolerance and/or longer fiber runs.

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

Operational Zone

Any optical tranceiver will operate when the power of the optical signal at the receiver is in the range between Receiver Sensitivity and Receiver Saturation.

 

Permanent Damage

Most receivers will be permanently damaged after exposure to an optical power of 5dBm or more.
