JDSU EPM 6xx-Series PIN photodiodes are designed for optical network
monitoring applications. The photodiode die is fabricated with a proprietary
InGaAs process in our wafer fab and assembled into a hermetically-sealed
package with antireflective-coated lens. A stainless steel bushing actively couples
the fiber to the package.
The fiber is reinforced with a rubber boot to relieve fiber-bending stresses. EPM
6xx-Series photodiodes can be produced with a variety of industry-standard
connectors or no connector at all. They are also available with mounting brackets
for both vertical panel and horizontal flush-to-board mounting.
Low-leakage versions (EPM 605LL and EPM 606LL) of the EPM 605 and EPM
606 are available with the same features, connectors, and brackets.
Small form-factor (SFF) packages EPM635 and EPM635-75 are designed for SFF
applications.
