Product Description
The FluxLight SFP-10/25G-CSR-S is SFP28 module for duplex optical data, communications up to 25.78Gb/s. It is with the SFP28 20-pin connector to allow hot plug capability; Digital diagnostic functions are available via an I2C. It has built-in clock and data recovery (CDR). This module is designed for multi-mode fiber and operates at a nominal wavelength of 850nm. The transmitter section uses a Vertical Cavity Surface Emitted Laser (VCSEL) and is a Class 1, laser compliant according to International Safety Standard IEC 60825. The receiver section uses, an integrated GaAs detector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC.
