What is a 40GBASE-ER4 Optical Module?
The 40GBASE-ER4 optical module is a high-performance solution designed for ultra-long-distance transmission. It operates under the 40G Ethernet standard and uses single-mode fiber for transmission, providing an impressive range of up to 40 kilometers. This module is ideal for applications that require long-distance data transfer, such as large enterprise networks, service provider backbones, and telecom networks.
Specifications of 40GBASE-ER4
The 40GBASE-ER4 optical module offers a data transfer rate of 40 Gbps, making it a high-performance solution for long-range transmission. It uses single-mode fiber (SMF) as the transmission medium, which is ideal for long-distance communication. The module operates across four distinct wavelengths in the range of 1264.5 nm to 1337.5 nm, allowing it to transmit data efficiently over extended distances. With a reach of up to 40 kilometers, the 40GBASE-ER4 is capable of providing seamless connectivity for long-haul network connections. Additionally, it uses an LC duplex connector, ensuring compatibility with most network hardware and simplifying the installation process.
How Does the 40GBASE-ER4 Optical Module Work?
The 40GBASE-ER4 module operates by using four separate optical channels, each transmitting data at 10 Gbps. These signals are carried over single-mode fiber using different wavelengths (WDM). The module is designed for very long-range data transmission, providing seamless connectivity over distances of up to 40 kilometers, which is ideal for metropolitan or wide-area networks.
The data is transmitted in light form over the fiber, where it is converted back into electrical signals at the receiving end, allowing for the high-speed, low-latency transfer of data over extended distances.
