Features

The 40G-QSFP-ER4-55 transceiver is a high-performance optical module designed for 40 Gigabit Ethernet (40GbE) applications, particularly for long-range transmissions. It converts four channels of 10Gb/s electrical input data into CWDM (Coarse Wavelength Division Multiplexing) optical signals using a 4-wavelength Distributed Feedback Laser (DFB) array. These wavelengths are combined into a single 40Gb/s optical signal via a multiplexer (MUX) and transmitted over Single-Mode Fiber (SMF), supporting extended reach up to 40 kilometers. On the receiver side, the 40Gb/s CWDM optical signal is demultiplexed into four individual 10Gb/s channels, each detected by a discrete photo diode. The signals are then amplified by a Transimpedance Amplifier (TIA) and a post amplifier before being output as electrical data.
