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.

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.

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.

What do MMF and SMF Stand for in Optical Modules?

Generally speaking, there are two types of optical fiber: Fiber that supports multiple propagation paths or transverse modes is called multimode fiber (MMF), while fiber that supports a single mode is called single-mode fiber (SMF).

Solutions for 400G Optical Modules in Data Centers

A 400G optical module, also known as a 400G optical transceiver, converts electrical signals into optical signals at the transmitting end, which are then transmitted via optical fiber. At the receiving end, the optical signals are converted back into electrical signals. They are primarily used for the conversion of electrical and optical signals in optical communications. Optical modules are very small and are generally used in servers, switches, routers, and wireless base stations across various network architectures.

What is the difference between 100G CWDM4 and 100G PSM4?

The QSFP28 100G CWDM4 optical module uses the QSFP28 form factor. It is a 100G transmission mode based on single-mode Coarse Wavelength Division Multiplexing (CWDM) technology. It is hot-swappable and employs a duplex LC interface. It transmits optical signals at four central wavelengths: 1271nm, 1291nm, 1311nm, and 1331nm. Each wavelength transmits 25G. Using CWDM technology, the QSFP28 100G CWDM4 optical module multiplexes these four central wavelengths onto a single-mode fiber for transmission. When used with single-mode fiber, the transmission distance can reach 25G. km, meeting the various long-distance transmission requirements of data center networks.
