Transceiver Optical Interface Specifications

Introduction

As an alternative to Fiber Optic Link Certification, you may consider measuring Optic Power of the signal at the receiver's end and compare those results with the tables below.

These are Transceiver Optical Interface Specifications for the most common Network Standards.  ANY optical tranceiver that lists itself as compliant with the standards, MUST be able to operate correctly when the power of the optical signal at the receiver fals in the range between Receiver Sensitivity and Receiver Saturation.  Transceivers by certain vendors may perform better, resulting in higher limits for loss and length.

These tabels will be updated we come accross specification for other interface types.

Permanent Damage

Most receivers used in enterprise networking will suffer permanent damaged when exposed to an optical power input of +5dBm or more. 

This should not be a problem, as Average Launch Power of an transmitter does not exceed +4.0dBm.
