Transporting a single data stream through an optical fiber can be costly and inefficient. Wavelength Division Multiplexing (WDM) can transmit multiple, independent data streams through a single optical fiber to better utilize the bandwidth…

NETGEAR AGM732F is a RoHS compliant SFP transceiver module designed expressly for high-speed communication applications that require rates of up to 1.25 Gbps. It is compliant with the Gigabit Ethernet standards, as well as the SFP Multi-So…

Several years ago, there was a report which said that the 10G/40G/100G optical transceivers would hit 1.44 billion dollars by 2014, driven by 10G SFP+ and tunable XFP modules. It is now 2014, and the forecasts have came true.Infontetics Re…

Optical transceivers are classified by wavelengths, data rates, reaches, packaging types, electrical and optical interfaces, temperature ranges, etc. The mannfacturing followings a process from discrete optics to optical subassembly and in…

What is an OTDR?OTDR, short for optical time-domain reflectometer, is an optoelectronic instrument used to characterize an optical fiber. It can be considered as the optical equivalent of an electronic time-domain reflectometer.OTDR inject…

Since the 1990s, many small form factor (SFF) fiber optic connectors have been developed to fill the interest in devices that may fit into tight spaces and permit denser packing of connections such as fiber patch cables. Some are miniaturi…

What is SFP+ Direct Attach Copper Cable?SFP+ direct attach copper cable, also known as Twinax Cable, is a SFP+ cable assembly used in rack connections between servers and switches. It consists of a high speed copper cable and two copper SF…

SFP Media Converter is a Fiber to Ethernet Media Converter with Fast Ethernet ports, dual-rate Fast/Gigabit Ethernet ports, or Gigabit Ethernet ports. The ports allow for flexible network configurations using SFP transceivers. And the Fast…

As we all know, SFP-OC48-LR2 is a type of Cisco SFP modules. But do you really know the meaning of the words in the SFP-OC48-LR2? I think the “SFP” and “LR2″ are known as SFP modules with 80km transfer distance by most people, while the “O…

What is an Optical Transceiver module?Optical Transceiver is a computer chip that uses fiber optic technology to communicate between other devices. This is opposed to a chip that transfers information electrically through metal wires and c…

What is really a SFP transceiver? SFP transceiver is a hot-pluggable fiber transceiver, of which the SFP stands for Small Form-factor Pluggable. The mechanical, electronic, and optical design and gratifaction derive from a Multi-source Agr…

The utilization of fiber optic cables for communication has opened up gates for communication multiplexing technologies that increase the capabilities at minimum costs. Coarse wavelength division multiplexing (CWDM) modulates different wav…

What is an Optical Switch?Optical Switch is a switch that enables signals in optical fibers or integrated optical circuits (IOCs) to be selectively switched from one circuit to another in telecommunication. Away from telecom, an optical sw…
