In today's optical communications market, there are a variety of transceiver modules with various types of interfaces. Because different types of cables/connectors/adapters are required for different interfaces, we need to pay more attenti…
The data center 100G has begun to be used on a scale, and the next-generation 400G is expected to begin commercial use by 2020. For 400G applications, the biggest difference is the introduction of a new modulation format, PAM-4, to achieve…
Shenzhen, China, April 30, 2018 − Recently, Gigalight has successfully developed two industrial-grade 100G optical transceivers: 100G QSFP28 LR4 (up to 10km) and 100G QSFP28 4WDM-40 (up to 40km). At the same time, these new products have b…
Twisted-pair cabling in the late 1980s and early 1990s was often installed to support digital or analog telephone systems. Early twisted-pair cabling (Level 1 or Level 2) often proved marginal or insufficient for supporting the higher freq…
Early cabling systems were unstructured, proprietary, and often worked only with a specific vendor's equipment. They were designed and installed for mainframes and were a combination of thicknet cable, twinax cable, and terminal cable (RS-…
The costs that result from poorly planned and poorly implemented cabling systems can be staggering. One company that moved into a new datacenter space used the existing cabling, which was supposed to be Category 5e cable. Almost immediatel…
We cannot stress enough the importance of reliable cabling. Two recent studies vindicated our evangelical approach to data cabling. The studies showed: Data cabling typically accounts for less than 10 percent of the total cost of the netwo…
In the last article, I have introduced the data cabling. Now I will list our own golden rules of data cabling to start the following content. If your cabling is not designed and installed properly, you will have problems that you can't eve…
"Data cabling! It's just wire. What is there to plan?" the newly promoted promoted programmer-turned-MIS-director commented to Jim. The MIS director had been contracted to help the company move its 750-node network to a new location. Durin…
INTRODUCTION Conventional duplex Fiber Optic Connectors, such as the SC Duplex defined by the ANSI Fibre Channel Standard, attain the required alignment tolerances by threading each optical fiber via a precision ceramic ferrule. The ferrul…
A Passive Optical Network (PON) is illustrated schematically in the figure below. A feeder fiber in the Central Office (CO) runs to some Remote Node (RN), which houses a passive optical power splitterkombiner. From there, around 32 fibers …
The throughput potential for optical fiber is extraordinary, and engineers continue to push its limits. In 2002, IEEE published its 802.3ae standard for fiber optic Ethernet networks transmitting data at 10 Gbps. Several variations were ex…
There are mainly three standards for optical fiber networking: 100BASE-FX, 1000BASE-LX, and 1000BASE-SX. 100BASE-FX 100BASE-FX is a version of Fast Ethernet over optical fiber. It uses a 1300 nm near-infrared (NIR) light wavelength transmi…
Optical communication systems' transmission capacity continues to be increasing forever. From telegraph systems carrying a few clicks per second a hundred years ago, towards the state-of-the-art, long-distance, DWDM Network systems carryin…
Thermoelectric Cooler (TEC) circuits are crucial for having accurate wavelength transmissions without wavelength drifts to adjacent channels. Traditionally, Coarse Wavelength Division Multiplexing (CWDM) solutions are chosen over DWDM due …
Combining transmitter and receiver into a single device leads to the concept of the transceiver. CWDM transceivers are based on the CWDM technology. The transceiver revolutionized many areas of optical communications, and the standards inv…
WDM filters provide access to all wavelength channels, where required. In Optical Termination Multiplexers (OTMs), all channels are terminated. Between two OTMs, use of a subset of channels are usually necesary. This leads to the concept o…
A systems analysis continues to be completed to consider dynamical transient effects in the physical layer of an Optical WDM Network. The physical layer dynamics include effects on different time scales. Dynamics from the transmission sign…
There are several trends for transceiver development with the majority of activities occuring at 10 Gbps, where DWDM XFPs are increasingly being deployed. Additionally, there is another new MSA standard called Quad Small Form Pluggable (QS…
The Wavelength Division Multiplexing (WDM) system uses a Multiplexer (MUX) at the transmitter to put multiple optical signals on the fiber along with a DeMultiplexer (DeMUX) at the receiver to split them from the fiber. The signals use dif…
Outlook of the WDM Netorks The throughput in optical networks is increasing inexorably, the backhauling traffic generated by triple-play and video-on-demand services being the main drivers. Therefore, the very first application for 100G sy…
