T1-SFP-25G-SR is an SFP28 module for duplex optical data, and communications up to 25.78GbPs, with an SFP+ 20-pin connector to allow hot plug capability. Digital diagnostic functions are available via an I2C. T1-SFP-25G-SR has a built-in clock and data recovery (CDR) is designed for multi-mode fiber and operates at a nominal wavelength of 850 nm. 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.
