SFP Module:Everything You Need To Know !

SFP (Small Form Factor Pluggable) is a compact, hot-swappable transceiver module that converts electrical signals into optical signals (and vice versa), enabling long-distance communication between devices. One of the main advantages of SFP modules is their hot-swappable nature, which allows them to be inserted or removed without powering down network devices.

What's the Difference Between Fiber Optic Transceivers?

SFP+, SFP+, SFP28, QSFP+ and QSFP28 are all types of optical module packages. These hot-swappable SFP+ optical modules can be used to connect network switches and other network devices for data transmission. Read this article to learn more about YXFiber fiber optic communications.

How to Choose 100g Transceivers for Network Upgrades

With the exponential growth in data, data center operators are continually seeking ways to optimize their infrastructure while reducing costs. One essential component in the data center ecosystem is the 100G transceiver, which facilitates high-speed data transmission.

The Differences between 10G SFP+ SR and 10G SFP+ LR Modules

There are many types of 10G optical modules, but the most classic and earliest are 10G SFP+ SR and 10G SFP+ LR. Both can transmit 10G Ethernet speeds, providing a stable, low-latency, and low-power network environment.

A Comprehensive Guide To 800G OSFP And Connectivity Solution

800G OSFP optical modules are already familiar to many. With 800G optical modules widely used in data centers by the end of 2025, they have become a focal point in the optical communication industry, attracting widespread attention.

A 10G DAC Cable, How Does It Differ From An AOC Cable?

A 10G DAC high-speed cable consists of a dual-core copper wire and SFP+ connectors at both ends, allowing direct connection to active devices. DAC cables include passive and active DACs, both of which can directly transmit electrical signals via copper wires. The difference lies in that the former can transmit without signal modulation, while the latter incorporates electronic components within the optical transceiver to enhance the signal.

Understanding BIDI SFP Optical Transceiver Modules

A BIDI optical module is a single-fiber bidirectional optical module, or BiDi (Bidirectional). Conventional modules are dual-fiber modules (connected by two optical fibers), with two fiber ports at the interface: a transmit port (TX) and a receive port (RX). BIDI modules, however, are single-fiber modules with only one fiber port. Different optical signals are transmitted and received within a single fiber; therefore, BIDI optical modules must be used in pairs. Visually, a BIDI module has only one port and uses only one optical fiber for connection.

400G FR4 vs. DR4 vs. SR8: How to Choose?

The continued growth of global data traffic is driving the upgrade of data center networks from 100G to 400G. As a common, efficient, and cost-effective solution for 400G networks, 400G optical transceivers can significantly improve system performance, increase transmission rates, expand bandwidth, and reduce broadband costs.

How to Choose Between Single-Mode and Multimode Fiber

When the geometric dimensions of an optical fiber (primarily the core diameter d1) are significantly larger than the wavelength of light (approximately 1 μm), dozens or even hundreds of propagation modes can exist within the fiber. Different propagation modes have different propagation velocities and phases, resulting in time delays and broadening of optical pulses over long transmission distances. This phenomenon is called modal dispersion (also known as intermodal dispersion).

25G/100G Module Technology Solutions in 5G Networks

Mobile communications network applications are currently transitioning from 4G to 5G. 5G (fifth-generation mobile communications technology) will rapidly develop and become a hot topic in the information and communications sector. The advanced construction and upgrade of bearer networks will drive a continued increase in demand for telecom network optical equipment. Simultaneously, demand for data center networks is exploding in the cloud computing era, and domestic internet companies, led by BAT, are entering a period of expanding IDC demand. This is leading to a rapid increase in demand for high-speed optical modules, such as 25G and 100G.

Detailed Explanation of Forward Error Correction Technology

As optical communication systems develop toward longer distances, greater capacity, and higher speeds, especially as single-wavelength rates evolve from 40G to 100G and beyond, transmission effects such as chromatic dispersion, nonlinear effects, and polarization mode dispersion in optical fibers will severely impact further increases in transmission rates and distances. To address this, industry experts are continuously researching and developing higher-performing FEC code types to achieve higher net coding gain (NCG) and improved error correction performance to meet the demands of the rapid development of optical communication systems.

Choosing a 400G Optical Transceiver for Data Centers

The key metrics for evaluating data center optical modules are density, power consumption, and cost. Thermal capacity is one of the indicators used to measure optical module power consumption; the greater the thermal capacity, the greater the power consumption the module can withstand. 400G optical modules are primarily categorized by package type: CDFP, CFP8, QSFP-DD, and OSFP. CDFP and CFP8 are larger in size and have higher thermal capacity, primarily used in the telecommunications market. QSFP-DD, backwards compatible with the previous QSFP-28, offers the smallest size and higher density. It is more suitable for short-distance data center use and has numerous supporters, including companies such as Facebook, Alibaba, and Tencent. Supporters of the OSFP MSA include Google and Arista. OSFP is slightly larger than QSFP-DD. QSFP-28 optical modules require an adapter to be compatible with OSFP sockets.

Building a 100G Data Center Leaf-Spine Network

As AI advances, data center computing power is further squeezed. Traditional data center networks can no longer meet the high bandwidth, low latency, and scalability requirements of AI development. To address this issue and accommodate the massive east-west traffic generated by AI computing, engineers are choosing leaf-spine network architectures for next-generation high-performance data centers. This article will introduce you to 100G leaf-spine networks, their topology, and their architecture, to help you better understand high-performance data center networks.

Introduction to 400G QSFP-DD ER4 Optical Transceiver

The QSFP-DD technology can double the number of ports used in data transmission while keeping the same size as the previous version, QSFP. It has been developed to provide better use of bandwidth and supports 400G applications. The interface of QSFP-DD carries both optical and electrical signals over eight lanes that transmit at a rate of 50G each, which adds up to an overall throughput speed of 400 G. This design is backward compatible with current QSFP connections, thus enabling easy adoption into existing network systems.
