IRM-8602S is an application field of an optical sensor and a photo-detector, not just representing the designation of a specific processor type. It is also classified as a type of remote receiver (RR).

An RR is an active optical transceiver used in long-distance communication networks. It has two ports, one to the host computer for transmission and one to the remote receiver for receiving data. The remote receiver uses its own receiver optics, processing capability, and amplification operations to process an incoming signal, amplify it, and convert it into an output data format compatible with the host computer. The IRM-8602S operates on an optical wavelength of 1550 nm.

The IRM-8602S is an integral part of fast Ethernet, Gigabit Ethernet, and Fibre Channel networks. In particular, the IRM-8602S RR makes it possible to quickly and cost-effectively reach the required data rates in the 2 ms to 10 ms window, thus eliminating the need for additional short-range receiver equipment in long distance networks.

The IRM-8602S platform consists of an in-house designed miniature receiver module with a 16-pin DIP form factor. This is combined with a wide variety of power supply and control interfaces. An integrated industry standard I/O power line and the communication protocols for signal transmission and control provide various configuration options.

The heart of the IRM-8602S is a high-speed, integrated photo-detection module. The detector core is a buried InP (Indium Phosphide) pre-amplifier. The metal-coated InP is used to achieve the highest optical sensitivity. The amplifier is optimized for double gain for both direct radiation and reflective radiation detection.

The IRM-8602S can detect and receive optical signals from distances up to 10 kilometers. This means it can serve as a remote receiver, effectively eliminating the need for long-range receivers. In addition, the IRM-8602S has a wide dynamic range (DR) of up to 13.6 dB, allowing it to operate in various transmit power conditions over a range of up to 150 kilometers. This further improves the cost efficiency of the system.

To further improve the system performance and signal decoding in the presence of ambient noise, the IRM-8602S uses a proprietary algorithm for noise rejection. This algorithm is able to reject noise up to 30 dB below the received signal level, allowing the receiver to efficiently decode weak signals. It also provides a wide range of threshold and gain adjustment for the individual receive channels.

The receiver electronics of the IRM-8602S is designed to run autonomously and in parallel with the host computer. This allows the receiver to process incoming signals quickly and accurately, without burdening the host computer. The continuous monitoring of the receiver’s operations is also done by the host computer.

In conclusion, the IRM 8602S is an evolutionary optical sensor and photo detector specifically designed for applications requiring a reliable and fast optical data transmission over a wide range of distances. Its integrated pre-amplifier and powerful signal processing algorithms make it highly effective in long-distance communication networks. Its robust design and high-quality components ensure a long service life.
