What Fiber Optic Attenuator Do You Use? LC Attenuator or SC?

Fiber optic attenuator is an essential passive component in the optical communication system. With the advancement of DWDM technology, as well as the potential to flexibly upgrade the reconfigurable optical add-drop multiplexer (ROADM), the demand for optical attenuator is sure to soar, especially for optical variable attenuator. Types of Fiber Optic Attenuators Optical attenuator takes a number of different forms….

which type of splitter should i select

How to Choose PLC Splitters

PLC splitter is a simple passive component which plays an important role during the applications of technologies like GPON, EPON, and BPON. It allows a strand of fiber optic signal being equivalently split into several strands of an optical signal, which can support a single network interface to be shared by many subscribers. During the selection of a PLC splitter, split…

Fibre Channel SFP: Why Fibre Channel?

With the advent of SFP transceiver communication, there have been many different standards. In network hardware, the advantage of SFP transceivers is that they allow a single device, such as a switch, to support different cabling and transmission formats. However, when you try to find out which optical transceiver type you need, you will encounter problems. Because there are several…

Half Duplex vs Full Duplex: What Are They

Half duplex and full duplex are two communication channels in telecommunications and computer networks. These communication channels provide a way to convey information. The communication channel can be a physical transmission medium or a logical connection on the multiplexing medium. Physical transmission medium refers to substances that can propagate energy waves, such as lines in data communication. Logical connections usually…


Understanding 1000BASE-LX SFP and 1000BASE-LH SFP

As the industry of optical communication develops rapidly, the design of optical fiber transceiver is more and more diversified, so as to meet the needs of Gigabit Ethernet. Therefore, various types of mini GBIC (SFP, Small Form-factor Pluggable) and SFP+ emerged. Gradually, we always see 1000BASE-LX SFP and 1000BASE-LH SFP on many websites. However, many people are puzzled about them….
