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 m fiber with or without a connector - Single mode 250 m 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.

Precautions for Use
Electrostatic discharge protection is imperative. Use of grounding straps, anti-static mats, and other standard ESD protective equipment is required when handling or testing an InGaAs PIN or any other junction photodiode. The flexible 250 m fiber coating can be mechanically stripped and provides protection for the optical fiber, under normal handling characteristics. Soldering temperature of the leads should not exceed 260 C for more than 10 seconds. Fiber pigtails should be handled with less than 10 N pull and with a bending radius greater than 1 inch.
