Why Is Single-mode Fiber So Attractive?

Since the invention of optical fibers in the early 1970s, the use of and demand for optical fiber today are quite numerous. With the explosion of information traffic due to the Internet, electronic commerce, computer networks, multimedia, voice, data, and video, the need for large amount of signal transmission is [ Continue reading…]

Are You Familiar with EDFA?

Signals travel through fibers over large distances with attenuation. Then the optical amplifiers are needed in the CWDM (corse wavelength divsion multiplexing) and DWDM (dense wavelength divsion multiplexing). Optical amplifiers are devices that can amplify optical signals directly without the need to convert them to electrical signals. EDFA (erbium doped fibre amplifier) [ Continue reading…]

SFP+ Cable Interconnect Assemblies Overview

SFP+ passive copper cable assemblies were developed specifically as a costeffective and lower-power alternative to optical fiber cables for short reach links in high-speed interconnect applications such as high performance computing (HPC), data center networking and network storage markets. The assemblies support data transfer rates up to 10 Gb/s per [ Continue reading…]

What Is Main Difference Between Single Mode SFP and Multi Mode SFP?

SFP transceivers are commonly used and necessary in our daily life. And there are two kinds: single mode SFP and multi-mode SFP. However, maybe most people don’t know these two SFP transceivers are different. The following are the differences between single mode SFP and multi-mode SFP.   Diameter of the Core [ Continue reading…]

An Irresistible Trend- 100 Gigabit Ethernet

In 2006, the IEEE 802.3 working group formed the Higher Speed Study Group (HSSG) and found that the Ethernet ecosystem needed something faster than 10 Gigabit Ethernet. Because the growth in bandwidth for network aggregation applications overpasses the capacities of networks employing link aggregation with 10 Gigabit Ethernet. HSSG is the [ Continue reading…]

Copper SFP Transceiver for 1000BASE Applications

In the past, because of low cost and compatibility with existing LANs, 100Mb/s Ethernet was very popular. As people’s increasing demands for faster delivery of information, high bandwidth Ethernet LAN is evolving. 1000BASE (1 Gbps Gigabit Ethernet) came around and brought Ethernet technology to a new stage. Gigabit Ethernet, as [ Continue reading…]

General Understanding of LC to LC Fiber Optic Cables

Fiber optic patch cords are also known as fiber optic jumpers or fiber optic patch cables. Fiber optic patch cords are designed to provide optical connection for fiber networks within structured cabling systems. It’s a quick and easy method for routing fiber patches in data centers, head-ends, cellular hubs and [ Continue reading…]

Why Is CWDM so Popular?

WDM (wavelength division multiplexing) technology transmitting multiple signals on a single optical fiber by using different wavelengths to carry each signal has been used since 1980s. In the middle of 1990s, dense wavelength division multiplexing (DWDM) enabled carriers to extend the capacity of the SONET/SDH rings in the network core, [ Continue reading…]

Multi-fiber Connectors for High Port Density

As the introduction of multimode optical fibers of the categories OM3 and OM4 are used for implementing 40 GbE and 100 GbE, though the small diameter of the optical fibers poses no problems in laying the lines, the ports suddenly have to accommodate four or even ten times the number [ Continue reading…]
