Currently, some established network companies offer mature 400G solutions, but they tend to be pricey. So, is there a more budget-friendly choice? Perhaps from white box switch manufacturers? Some of the noteworthy 400G white box switch manufacturers include : Asterfusion, Accton, UfiSpace, Edgecore Networks, Delta Networks, and Celestica
In the wake of COVID-19, network carriers constantly face the challenge of keeping up with bandwidth demands. Over the past three years, there has been a surprising surge in network traffic. Top Cloud Service Providers (CSPs) and networking forecast reports show that, since 2020, 400G Ethernet is becoming the dominant technology. This explosive growth in traffic can be attributed to factors like video streaming, cloud computing, data centers, Artificial Intelligence (AI), Machine Learning (ML), and the growing number of IoT devices.
Also known as 400 Gigabit, 400GbE, 400Gb/s, or Terabit Ethernet, 400G (400 Gigabit Ethernet) is the newest cloud infrastructure generation and offers four times the speed of its predecessor, the 100G standard. Terabit Ethernet refers to Ethernet transmission at a staggering one trillion bits per second (1 Tbps). Although true Terabit Ethernet is a future concept, for now, it implies speeds exceeding 100 Gbps.
Initially labeled as IEEE 802.3bs, 400G technology was officially approved in December 2017. It introduced new standards such as Forward Error Correction (FEC) for enhanced error performance. Adhering to these guidelines, early trials and initial deployments of 400G network elements have been successful.
The various applications for 400G Ethernet networks can differ based on specific industries, but here are some popular situations where they prove advantageous:
Did you know that a 400G Ethernet link actually has a line rate of 425 Gbps? It’s all thanks to the IEEE 802.3bs standard, which was developed for 400G networks. like metioned before; adding to its awesomeness, it incorporates a forward error connection (FEC) process that detects and fixes transmission errors with an extra 25 bits.
So, what makes 400G transmission possible? Say hello to 4-level pulse amplitude modulation (PAM4)! With PAM4, operators can use either 8 lanes of 50G or 4 lanes of 100G for various form factors like OSFP and QSFP-DD. This innovative optical transceiver design allows up to 400 Gbit/s Ethernet data transmission over multiwavelength or parallel fibers.
However, multilevel modulation leads to greater analysis complexity. No worries though – advanced tools such as PAM4 eye diagram histograms and pre-emphasis and equalization capabilities come to the rescue!
Here’s a handy chart breaking down distance, fiber mode, designation, and number of fibers requirements for both 200G and 400G.
The traditional manufacturers of 400G switches include: Cisco, Arista Networks, Juniper Networks, Aruba, Nvidia……
