What size pins are used for LC FC and SC pigtails
The size of the pins and sleeves used by the LC connector is the same as that used by ordinary SC and FC, which is 1. 25mm, so its size is only half of that of SC/FC. What is a Fiber Connector? The optical fiber connector is a kind of detachable passive optical component used. Here are the five most widely used fiber connector types: 1. Known for its square shape and push-pull coupling, SC is widely used in FTTH (Fiber to the Home) deployments and data. They are small, often overlooked components, yet they are essential for ensuring high-speed, low-loss, and reliable optical transmission. As data centers, telecom networks, and enterprise infrastructures migrate to fiber, understanding connector types becomes critical for engineers, technicians. The primary function of a fibre optic connector is to facilitate the transmission of optical signals between optical fibres to the target device, thereby enabling high-speed, stable, and high-quality data transmission.

ONU optics splitter OLT
A GEPON system usually consists of an OLT (Optical Line Terminal) at the service provider's central office and multiple ONU (Optical Network Units) or ONT (Optical Network Terminals) close to the end user as optical splitters. It is a passive device connecting OLT and ONU. The optical splitter has one upstream optical interface and several downstream optical interfaces. It forms the backbone of the PON architecture. The ODN can typically cover distances up to 20 km or more, depending on the network design.

What size cable tray should be used for wiring in the workshop
Best Size: Here, deep trays (75mm to 150mm) are used since power cables are typically thick and heavy. Data cables, such as your Wi-Fi or computer ones, are extremely sensitive. They do not get hot; however, they do not like to hang or sag. In practice, cable tray dimensions are a system of interrelated measurements —width, depth, length, and material thickness—that directly affect cable fill compliance, heat dissipation, structural loading, and long-term expandability. What Is the Standard Size of Cable Tray? What Is. Choosing the appropriate size and dimensions for a cable tray is critical for performance, maintenance, and potential future improvements. It is grounded on 40 years of experience in the manufacturing. Ladder cable tray is available in widths of 6, 9, 12, 18, 24, 30, 36, 42 and 48 inches with rung spacings of 6, 9, 12 or 18 inches.

AI server handed over to Iranian company
Stargate is a $500 billion joint venture between OpenAI, SoftBank, and Oracle to build AI data centers, announced in January 2025. War in the Middle East is having unfortunate consequences for AI giants, with infrastructure emerging as a new pressure point. Now, OpenAI's US$30bn AI data centre in the UAE – which is currently under development – has been singled out by the Iranian Revolutionary Guard Corps (IRGC) in a video. Iran has issued a new threat against a US interest: the $30 billion Stargate AI data center in Abu Dhabi. The IRGC released a video vowing retaliatory. This Amazon data centre sits on the outskirts of Abu Dhabi, directly across the water from the Iranian coast. Stocked with high-powered computers that run day and night, this structure is where “the cloud” takes on physical form. Amazon has six data centres across Bahrain and the United Arab. Iran has launched its National Artificial Intelligence (AI) Platform, developed by 100 Iranian researchers, marking a significant milestone in the country's pursuit of technological advancement and self-sufficiency. However, two key factors — Tehran's global economic isolation, and its deeply.
