25G SFP28 Active Optical Cable

25Gb/s SFP28 Active Optical cable transceiver consists of several key components, including the LD driver, limiting amplifier, digital diagnostic monitor, VCSEL laser, and PIN photo-detector. This module is designed to support data links up to 100m in 50/125um multimode optical fiber. Additionally, the SFP28 SR module meets SFI electrical specifications for the electrical interface.

The transmitter input and receiver output impedance is 100 Ohms differential, with internally AC coupled data lines. Differential termination is provided to reduce common mode conversion and ensure quality signal termination for minimal electromagnetic interference. SFI operation typically requires improved FR4 material or standard FR4 with one connector.

The transmitter within the module converts 25Gbit/s serial PECL or CML electrical data into optical data compliant with the 25GBASE-SR standard. Additionally, a Transmit Disable (Tx_Dis) feature is included for compatibility with open collector systems.
