Abstract
A pluggable OTDR is disclosed that is utilizes a specific architecture that separates its passive optical elements from the remaining active optical and electrical elements. The set of active elements (i.e., laser, photodetector, and control/processing electronics) can arranged in a manner similar to a small form-factor pluggable (SFP) optical transceiver and assembled within a housing that meets these requirements. The passive optics may be incorporated into a separate optical fiber pigtailed component that is attached between the active OTDR module and a fiber span under test.
