AVAGO HFBR-1522Z Compatible Domestic Alternative Optical Module

product presentation
The FT-1522Z/2522Z series fiber optic transceiver modules, when used in conjunction with 650nm plastic optical fiber (POF), deliver high-performance and cost-effective fiber optic communication links for industrial, power generation, medical, transportation, gaming, and other application fields. Driven by a 60mA current, the FT-1522Z achieves a typical minimum transmission distance of 90 meters.The FT-1522Z/2522Z series is fully compatible with AVAGO's HFBR-1522Z/2522Z series products. It supports industry-standard plastic optical fiber interfaces and features a horizontal form factor. These modules are compatible with plastic optical fibers of 1mm diameter and HCS (Hard-Clad Silica) fibers of 200μm diameter.

The FT-1522Z is a transmitter, encapsulated with a high-power LED chip that has a peak wavelength of 650nm. When paired with a 1mm-core plastic optical fiber and driven by a 60mA current, its typical output optical power is -5dBm.The FT-2522Z is a receiver, consisting of a high-gain transimpedance amplifier (TIA) integrated with a photodiode. Its output stage adopts an open-drain configuration and supports a maximum output voltage of 18V. To enhance the stability of the receiver's output pulse width, the receiving chip is designed with an automatic pulse width calibration circuit, which ensures the pulse width distortion is within ±20ns.
