COMMUNICATIONS COMPONENTS
C-Band, L-Band, Pass Band Low Leakage PIN Photodiodes
EPM 6xx Series
Key Features
• Electro-optical
- Low back reflection
- High responsivity in L-band at 1625 nm (EPM 606)
• Packaging
- Single mode 900 µm fiber with or without a connector
- Single mode 250 µm fiber without a connector
- Small form factor (SFF) package available
Applications
• C- and L-Band monitoring
• High sensitivity monitoring
• EDFA and DWDM
• 40 and 10 Gb/s line monitoring
• 980 forward pump
• 1310 and 1550 PONs
The 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 an hermetically-sealed
package with antireflective-coated lens. A stainless steel bushing is used to actively
couple the fiber to the package.
The fiber is reinforced with a rubber boot, which relieves fiber bending stresses.
EPM 6xx Series photodiodes can be produced with or without a variety of
industry standard connectors. They are also available with mounting brackets,
allowing 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.
Besides, we also offer the small form factor (SFF) packages (EPM635 and
EPM635-75) that are designed for the SFF applications.
