Download Datasheet Technical Support

TheFCI-InGaAs-XX-XX-XX with active area of 70µm and 120µm are part of OSI Optoelectronics family of high speed IR sensitive detectors with fiber pigtail package. The single/multi-mode fiber is optically aligned to either the hermetically sealed InGaAs diode in TO-46 lens cap package enhancing the coupling efficiency and stability or directly to the InGaAs diode mounted on a ceramic substrate. High responsivity and low capacitance make these devices ideal for very high-bit rate receivers used in LAN, MAn, WAN and other high speed communication and monitoring/instrumentation systems. Angle polished connectors and custom packages are also available.

For solution involving FC connector and TO-46 attachment, user(s) may consider either FCI-InGaAs-70-SM-Fc or FCI-InGaAs-120-SM-FC in single-mode operation. Similarly, the multi-mode variant is available in FCI-InGaAs-120-MM-FC using 62.5/125 fiber. The back-reflection of -30dB typical is to be experienced in multi-mode based solution.
