The R768 is a 40 Gbits/s fiber-optic receiver with high data rate, single-mode fiber connector and compact butterfly package.
The R768-Type OC-768/STM-256 Lightweight Receiver is a 16‑pin surface‑mount device with a single‑ended V‑connector, designed for high‑speed fiber‑optic applications up to 40 Gb/s. It incorporates a PIN photodetector, a wide‑band linear pre‑amplifier, and a single‑mode fiber pigtail with an FC/PC connector.
The receiver is intended for L‑band (1.6 µm) SONET OC‑768 and SDH STM‑256 networks, extended‑reach datacom, digital video, and other high‑speed telecom uses. The data sheet lists electrical and optical characteristics, absolute maximum ratings, and ordering information, including part numbers for various connector options.
