IP54 VS IP55 VS IP65 HOW TO CHOOSE THE RIGHT

How to choose the right model from a pigtail brand

When selecting the right automotive connector pigtail, prioritize compatibility with your vehicle's make, model, and year, along with high-quality materials like UV-resistant insulation and corrosion-proof terminals—key factors in ensuring long-term reliability. Check out this automotive connector selection guide and a few ways to find the electrical connector you need in 30 seconds or less. While the concept is the same, pigtails generally fall into two distinct categories based on the medium they transmit: electrical current or light.

How to Choose a Small Network Cabinet Model

That shift means size, accessibility, and thermal realism matter more than ever. If you're a typical user, you don't need to overthink this: start with a 6U–10U wall-mounted cabinet with ≥15" depth, lockable front door, and adjustable rails. This quick reference table shows you exactly which cabinet size works best for different project types. Network cabinets serve as secure and organized storage units for servers, switches, routers, and other network equipment.

How to Choose a Base Station Optical Module

This article explores how to choose the right optical module based on key factors like transmission distance, data rate, wavelength, and future scalability needs. Optical modules are pivotal components in optical fiber communication systems, operating at the physical layer—the foundational level of the OSI model. Their primary role is to facilitate optoelectronic conversion, transforming electrical signals into optical signals, and vice versa. Which optical modules are commonly used in 4G base stations? In this blog, ETU-LINK will talk about 4G base stations and common types of optical modules.

How to distinguish left from right in fiber optic patch cords

When looking at the fiber end-face, fiber positions are numbered from left to right starting with P1. The P1 position is also commonly marked with a white dot on the side of the connector housing. 0 Standard (Commercial Building Telecommunications Cabling Standard) defines the A-B polarity scenario for discrete duplex patch cords, with the premise that transmit (Tx) should always go to receive (Rx) — or "B" should always connect to "A" — no matter how many segments there are. Because fiber duplex links rely on matched transmit-receive alignment, polarity determines how cables, connectors. One of the most common faults when a newly-installed fiber network does not work is the fibers are not. Fiber polarity is the direction that light signals travel from one end of a fiber optic cable (link) to the other.

How to Choose an Industrial Switch for Monitoring

Selecting the right Ethernet switch for your industrial network depends on several key factors, including application requirements, distance, performance, security monitoring and, of course, overall cost. An industrial Ethernet switch is designed specifically to withstand harsh conditions such as extreme temperatures, humidity, vibration, and electrical noise found in manufacturing plants, oil refineries, power stations, and transportation systems. These switches come in two types, managed and unmanaged offer Gigabit, and PoE capabilities with various industry certifications. A managed industrial ethernet switch runs all the same forwarding logic, plus a configuration layer — accessible via web GUI, CLI, or SNMP (v1/v2c/v3) — that lets you define how the network behaves, monitor what it's doing, and recover from faults without a site visit.
