Features

The 40G-QSFP-ER4 transceiver is a high-performance optical module designed for 40 Gigabit Ethernet applications, particularly for long-range transmissions. It converts four channels of 10Gb/s electrical input data into CWDM optical signals using a 4-wavelength DFB Laser array. These wavelengths are combined into a single 40Gb/s optical signal via a MUX and transmitted over 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 and a post amplifier before being output as electrical data.

FAQs

I need to transmit 4K video and real-time transaction data. How is the stability of ER4 ensured?

Does the warranty policy cover optical performance degradation of modules?

Can the module be used in an outdoor cabinet at -20°C?

Can the 40G port of the ER4 module be split into four 10G interfaces for use?

How to use the DOM function of the module?
