When optical transceiver was first deployed, verifying the performance of it was straightforward. The entire network was installed and owned by a single company, and if the system worked, extensive testing of the subcomponents was unnecessary. Today, however, most optical networks use components tha

Definition:Optoelectronics is the study and application of electronic devices that source, detect and control light, usually considered a sub-field of photonics. In this context, light often includes invisible forms of radiation such as gamma rays, X-rays, ultraviolet and infrared, in addition to vi

Definition:The small form-factor pluggable (SFP) is a compact, hot-pluggable transceiver used for both telecommunication and data communications applications. The form factor and electrical interface are specified by a multi-source agreement (MSA) under the auspices of the SFF Committee. It interfac

DefinitionSingle-mode optical fiber (SMF) is an optical fiber designed to carry light only directly down the fiber - the transverse mode. Modes are the possible solutions of the Helmholtz equation for waves, which is obtained by combining Maxwell‘s equations and the boundary conditions. These modes

Introduction:BiDi transceivers communicate using only one fiber, where traditional communication is with two lines of fiber. To achieve this they use two different wavelengths (colors). For the 10G, these are the 1270nm/1330nm combination. On one side you will have the transceiver which is sending o

DefinitionWavelength division multiplexing (WDM) is a technology or technique modulating numerous data streams, i.e. optical carrier signals of varying wavelengths (colors) of laser light, onto a single optical fiber. WDM enables bi-directional communication as well as multiplication of signal capac

DefinitionMulti-mode optical fiber is a type of optical fiber mostly used for communication over short distances, such as within a building or on a campus. Typical multi mode links have data rates of 10 Mbit/s to 10 Gbit/s over link lengths of up to 600 meters. In fiber optics technology single mode

As a widely used and powerful optic component, optical modules are irreplaceable in fiber optic communication. With the increase of demands for bandwidth and performance of fiber optic communication and network system, the types and performance of optical modules are getting rich and strong, how to

In the field of optical communications, there are many devices with similar functions. For example, optical modules and fiber media converter are equipment for photoelectric conversion, and sometimes they have different names. Optical module is also known as optoelectronic module while fiber media c
