MF443 MF443 PT 13451.11 TO-46 Package 15169.11 Pigtail including 1.4m of 50/215mm multi mode fibre and SC connector
Note: The rated Responsivity applies to all options.
Description
This device consists of a PIN photodiode and a transimpedance amplifier assembled in a TO-46 package. It is designed for FDDI, ATM and SDH/ Sonet up to 155 Mbps. The AGC (Automatic Gain Control) ensures a wide dynamic range. Its doublelens optical system is designed for single-mode fiber as well as for multimode fiber with core diameter up to 62.5m.
