Applications

The 1.25Gbps PIN-TIA TO-CAN series integrates an InGaAs PIN photodetector with a transimpedance amplifier in a compact TO-CAN package. With a single +3.3V supply, differential output, and 2.0 GHz typical bandwidth, it delivers high sensitivity and low noise at data rates up to 1.25Gbps, making it suitable for both high-speed telecommunications and data communication.

High-Speed Telecommunications

In telecom networks, this receiver is deployed in gigabit-class access and metro systems, where cost-effective, low-noise detection is the primary requirement. Its typical sensitivity of -30 dBm at 1.25Gbps makes it well suited to the ONU side of GPON and other PON deployments, ensuring reliable gigabit-plus service to end users while keeping equipment costs under control. The wide operating temperature range of -40°C to +85°C supports outdoor telecom equipment. As the industry moves toward higher-capacity access standards, the role of 1.25G receivers remains foundational in existing PON infrastructure.

Data Communication

In data communication, the 1.25Gbps PIN-TIA receiver serves as a reliable front-end component in gigabit optical modules, enterprise switches, and short- to medium-reach optical links. Its high linearity and low dark current help preserve signal integrity in high-volume deployments, while the compact TO-CAN form factor supports dense module design. Typical supply current of 21 mA and single +3.3V operation make it an energy-efficient choice for green telecom and datacom deployments.
