케이블링 산업 현황
For years, we’ve heard about FTTX making its way into the horizontal LAN—fiber to the desktop, fiber to the office, fiber to the enclosure, fiber to the zone, etc. Often referred to as “fiber to the edge” or FTTE, most of these deployments have traditionally been for high-security government environments or specialty applications or devices. Now, as bandwidth requirements continue to increase and the commercial real estate industry is trending towards smarter and more sustainable buildings, the question of using fiber vs. copper is more relevant.

Driven by large hyperscale and cloud data center providers, advancements in signaling and transceiver technology have led to the development of next-generation transmission speeds. There are now multiple options available for 400G Ethernet applications over multimode and single-mode fiber with more on the horizon. And it doesn’t stop there—big players like Google, Facebook, and Microsoft are driving innovation to support 800 Gig and 1.6 Terabit applications, and the IEEE Beyond 400 Gig Ethernet Study Group is already defining objectives.

What is Insertion Loss?
Insertion loss is the amount of energy that a signal loses as it travels along a cable link. It is a natural phenomenon that occurs for any type of transmission—whether it's electricity or data. This reduction of signal, also called attenuation, is directly related to the length of a cable—the longer the cable, the greater the insertion loss. Insertion loss is also caused by any connection points along a cable link (i.e., connectors and splices).

사용 중인 구성 요소의 유형에 따라 다양한 유형의 광 커넥터가 있지만, 네트워킹 산업 전체에 걸쳐 LC 커넥터가 매우 흔해졌습니다.
플라스틱 LC 커넥터
연결부에 플라스틱을 사용하는 경우 플러그를 꽂은 다음 거의 건드리지만 않으면 완벽하게 작동합니다. 하지만 예를 들어 광케이블 테스트 참조 코드를 사용하여 이러한 연결을 반복적으로 수행하고 분리해야 하는 경우, 반복적인 구부림으로 인해 하우징의 신축성 래치가 파손되는 경우가 많습니다.

Since the original IEEE 802.3af Type 1 power over Ethernet (PoE) standard that delivered up to 15.4 Watts (W) was first introduced in 2003, the technology has evolved to include Type 2 (up to 30 W), Type 3 (up to 60 W), and Type 4 (up to 90 W). That means PoE voltage now supports everything from phones, Wi-Fi access points, and surveillance cameras, to laptops, digital displays, and even facility-wide LED lighting—all requiring various levels of PoE power.

In the data center space, cross connects and interconnects via patch panels are commonly used between active equipment purely for management and flexibility, typically residing between switch tiers or between switches and servers. Some scenarios even call for using multiple cross connects or interconnects within the same channel, or a combination thereof.

Cleanliness has long been a best practice in fiber optic installation, but it’s not just the fiber end faces you need to worry about. If you think about how often your cabling tools and testers are touched by you and others on the job site, it’s clear that they too need to be cleaned.
While a fiber end face and your Fluke Network tester are cleaned for two different reasons, the goal in both instances is to clean without causing any damage.

Equipment cords are an integral part of any network—whether it’s a fiber jumper used to make connections between fiber patching areas and switches in the data center or a copper patch cord out in the LAN to connect end devices to the work area outlet.
