SRP00254x

The SRP00254x / SRP00255x is an optical receiver module which uses a highspeed PIN photodetector coupled with a hybrid low noise transimpedance amplifier (TIA) for 1300 nm or 1550 nm optical communications. The PIN-Photodiode is made of InGaAs/InP and has an active diameter of 75 m.
 
The function of the PIN-TIA module is to detect input optical power, to transduce the incident radiation into current and then to convert the current into a voltage and drive 50 line.The low input noise current density of the transimpedance amplifiers provides the optical receiver module, when used with appropriate filtering, with ample sensitivity for realizing minimum input power requirements.Designers of optical receivers can use the module in any application that benefits from integration of the photodiode and TIA into a TO coaxial package. Typical for such applications of SRP00254x / SRP00255x are receivers for digital crossconnects, digital loop carriers,add/drop-multiplexers and optical network units.

The SRP00254x / SRP00255x is also beneficial because it operates from a single +5 volt supply and is packaged in a compact, hermetically sealed module. In addition,the SRP00254x / SRP00255x, which has three isolated leads, requires fewer electrical connections and no additional shielding compared with discrete implementations of the photodetection / TIA-function. These features make the SRP00254x / SRP00255x an excellent optical receiver module of benefit in other fiber optic receiver applications.
