Fiber cassette is an integral part of cable management in the data center. It provides ease of management, high flexibility, and time-saving. This article provides a comprehensive introduction to fiber optic cassettes. What is a Fiber Cassette? A fiber cassette is a type of networking device for effective cable management. It offers integrating splicing solutions and patch cords into a compact package, thereby realizing simple access to the adapters and connectors. Just taking rack-mounted fiber cassette as an example, it is usually used in data centers. Rack-mounted fiber cassette is typically a standard 19 inches, and it can vary in height, including 1 RU, 2 RU, 3 RU, 4 RU, etc. Fiber Cassette Types Fiber cassette is divided into the use case, front panel, and fiber termination. Use Case According to the use case, 1RU rack-mounted fiber cassette is divided into three types: clamshell, sliding, and rotational fiber cassettes. Clamshell fiber cassette is the earliest type of

Direct attach cable (DAC) and active optical cable (AOC) is crucial high-speed interconnect cabling solutions in data centers and high-performance computing applications. DAC and AOC cables are plug-and-play, allowing the users to optimize the existing network without new optical fiber cabling. This article will discuss the differences between DAC and AOC cables. DAC Cable VS. AOC Cable DAC cable consists of a Twinax copper cable terminated with SFP+/SFP28/QSFP+/QSFP56/QSFP28 connectors on both ends, which can provide an electrical connection directly to active equipment. DAC cable can be passive or active. Passive and active DAC cables can transmit electrical signals directly over copper cables. The passive DAC cable can deliver without signal conditioning, while the active DAC cable has electric components inside the transceivers to boost signals. AOC cable consists of a multi-mode fiber optic cable terminated with SFP connectors on both ends, which requires external power to comp

Direct Attach Cable (DAC) is used in data centers. It provides low latency, low power consumption, low cost, and high-density alternative cabling solution for high-speed 10G-400G interconnect to fiber optic transceivers. This article will introduce DAC cable and its types and applications. What is a Direct Attach Cable? A direct attach cable (DAC), also called direct copper cable or high-speed cable is a type of factory-terminated Twinax cable that connects directly into transceivers and can be brought in several lengths for short distances of up to 15 meters. DAC cable consists of fixed lengths of shielded copper coaxial or fiber optic cable with fixed pluggable transceivers on either end with varying gauges from 24 to 30AWG. DAC cable can achieve interconnection up to 15m via twin axial copper cable, and reach 100m over active optical cable at 10Gbps, 40Gbps, or beyond. Direct Attach Cable Types There are different types of DAC cables: direct, breakout, passive and active. Dir

As data rates rise and data center grows in size, copper cable is getting stretched to its limits. However, active optical cable (AOC) has emerged to replace copper cable in data centers and high-performance computing (HPC) applications. It provides high-speed, high reliability, high flexibility, and low power consumption. This article will provide some knowledge of AOC cable. What is an Active Optical Cable? Active optical cable (AOC) is an optical fiber jumper cable terminated with optical transceivers on both ends. It uses electrical-to-optical conversion on the cable ends to improve the speed and distance performance of the cable without sacrificing compatibility with standard electrical interfaces. Active Optical Cable Structure AOC cable consists of the fiber optic connector and fiber cable. The connection between fiber cable and fiber optic connectors is not separable. If the fiber optic connector or fiber cable needs to be changed, they should be removed together. The el

A fiber optic attenuator is mainly used in fiber optics to debug optical power performance and optical instrument calibration correction, and fiber signal attenuation to ensure the optical power is stable and desired level in the link without any changes on its original transmission wave. This article provides a comprehensive understanding of fiber optic attenuators. What is a Fiber Optic Attenuator? A fiber optic attenuator also called an optical attenuator is a passive device used to reduce the power level of an optical signal in free space or an optical fiber. It provides low insertion loss, precise attenuation values, and easy operation features. In addition, fiber optic attenuator is usually used in single-mode long-haul applications but is also available in multi-mode attenuators. Working Principle of Fiber Optic Attenuator There are three working principles of fiber optic attenuators:gap-loss, absorptive and reflective principle. 1.Gap-loss Principle The gap loss princip

With ever-greater bandwidths and network connections to deal with in data centers, traditional duplex fiber patch cords like LC fiber patch cords no longer meet the demands. To solve this issue, MTP/MPO fiber optic cable that houses more fibers in a multi-fiber MTP/MPO connector was introduced in the market as a practical solution for 40G/100G/400G high-density cabling in data centers. This article will introduce different MTP/MPO cable types and their applications. What is MTP/MPO Cable? MPO (multi-fiber push-on) is the first generation of clip-clamping multi-core fiber optic connectors. MTP is an advanced version of MPO with the better mechanical and optical performance. They look similar and are fully compatible and interchangeable. MTP/MPO cable consists of MTP/MPO connector and optical fiber. MTP/MPO connector has a female type (without pins) or a male type (with pins). MTP/MPO connector increases the fiber optic cable density and saves circuit card and rack space, which is w

The fiber optic patch cord and fiber optic pigtail are crucial in the fiber optic network. They have many similarities and also differences in some aspects. Understanding the similarity and differences will help you to make the best choice for your project. This article will explain the similarity and differences between fiber optic patch cords and fiber optic pigtails. Similarity of Fiber Optic Patch Cord and Fiber Optic Pigtail Fiber optic patch cords and fiber optic pigtails have a similar structure. They are available in single-mode (SM) and multi-mode (MM) fibers, simplex, and duplex. In addition, they can terminate with many types of fiber optic connectors, including SC, LC, FC, ST, MTRJ, MTP/MPO, MU, E2000, etc. Fiber Optic Patch Cord Vs. Fiber Optic Pigtail 1. The fiber optic pigtail has only one end with a fiber connector installed, and the other end is left open. While both ends of a fiber optic patch cord have connectors installed. 2. The fiber optic patch cord could

Fiber optic pigtail provides a fast way to make communication devices in the field. It is designed, manufactured, and tested according to protocol and performance dictated by industrial standards, which will meet your most stringent mechanical and performance specifications. This article provides some basic knowledge of fiber optic pigtails. What is a Fiber Optic Pigtail? A fiber optic pigtail is a single, short, usually tight-buffered fiber optic cable with a factory-installed connector on one end, and un-terminated fiber on the other end. A fiber optic pigtail is used to terminate fiber optic cables via mechanical or fusion splicing. The end of the pigtail is stripped and fusion spliced to a single fiber or a multi-fiber trunk. The pigtail is spliced to each fiber in the trunk and "breaks out" the multi-fiber cable into its component fibers for connection to the end equipment. Fiber Optic Pigtail Types Fiber optic pigtail is available in several types: fiber, connec
