Difference between CWDM and DWDM networks Wavelength-division multiplexing (WDM) has become increasingly popular in fiber-optics communications as it allows transmission of multiple signals onto a single optical fiber. WDM enables bidirectional (BiDi) communication over one strand of fiber by sending signals utilizing different wavelengths that can be spaced apart. WDM systems are very popular in… Read More

BiDi Transmission BiDi or bidirectional transmission relies on transceivers that have two different wavelengths in order to accommodate transmission in both directions on just one fiber. Unlike conventional optical transceivers which have two ports, BiDi transceivers only have one. Bidi transceivers are able to transmit signals in both directions by different center wavelength using wavelength… Read More

What is DDM in Transceivers? DDM stands for Digital Diagnostic Monitoring according to the industry standard MSA (Multi-Source Agreement). DDM is also commonly known as DOM which stands for Digital Optical Monitoring. When purchasing a transceiver today you are given the option with or without DDM/DOM. Most of the transceivers in use today feature the… Read More

Light sources used for fiber optic transmission need to meet several criteria: they must be the right wavelength, be able to be modulated fast enough to transmit data and be efficiently coupled into fiber. Lasers have proven to be ideal light sources because of their high bandwidth capability and narrow spectral output. There are 3… Read More

Bandwidth requirements have led to an explosive growth in hyperscale datacenters. Cisco predicts that by 2020 global cloud IP traffic will meet or exceed 14 zettabytes. IP video traffic will account for 82 percent of all IP traffic. All this means that 100G and higher data centers are becoming the norm. The 100G QSFP28 transceiver… Read More

Do you sell to the government? Are your products on the GSA schedule? If you want to sell your products to the federal government, they must be TAA (Trade Agreement Act) compliant. This rule is now more strictly enforced than before and not complying may lead to penalties and suspensions. To be TAA compliant, Customs… Read More

Fiber optic cables are now being used in a wider variety of applications than ever before. There are two types of fiber – Single Mode and Multi-Mode. Most people know that single mode fiber is more popular for longer distances while multi-mode is preferred for shorter links, but what is the real difference? We try… Read More

MPO or MTP terminated cables are widely used in high density cabling environments like data centers. Traditional, tight-buffered multi-fibre cable needs to have each fiber individually terminated by a skilled technician. MPO cable which carries multiple fibers, comes pre-terminated. Factory terminated MPO / MTP connectors  commonly have either 12 fiber or 24 fiber array. People… Read More

Rapid demand for bandwidth has led datacenters to upgrade networks from 10G and 40G to 100G and now 400G. Cisco predicts that by 2020 global cloud IP traffic will meet or exceed 14 zettabytes. To meet this continuously growing demand of IP traffic, transceiver manufacturers have been working on viable 400G interconnects. Here, we look… Read More

Silicon photonics has been getting much interest lately. In simple terms, silicon photonics is building advanced optical components with silicon materials and related CMOS manufacturing technology. Datacom is by the far the most important application for silicon photonics. Other emerging applications include gas/chemical sensors, circuit-level interconnects, video connectivity devices, and automotive lidars. Traditionally optical components have… Read More

Optical multiplexers (muxes) and demultiplexers (demuxes) form the foundation of DWDM networks deployed by the telecommunications industry. In addition to their use at terminal points, mux/demux components are also used as building blocks of advanced network elements such as optical add/drop multiplexers (OADMs) and optical-crossconnect switches. This post talks about different mux technologies currently used… Read More

Reducing cable congestion in constrained spaces is an important factor in designing fiber systems for data centers and large enterprise equipment rooms and data centers. Network designers turn to multi-fiber MTP/MPO cabling to overcome this challenge. Ensuring correct polarity across the system becomes more complex with higher data rates. TIA-568 standard has approved 3 methods… Read More

100G QSFP28 transceivers use different optical technologies to transmit data to different distances. Shorter reaches typically use Vertical Cavity Surface Emitting Lasers(VCSELs) and longer reaches use Electro-absorption modulated lasers (EMLs) or Directly Modulated Lasers (DMLs). The recent shortage of EML lasers in the market forced design engineers to come up with an alternate solution for… Read More

QSFP28 has become the dominant form factor for 100G networks. The interconnect offers four channels of high-speed differential signals with data rates ranging from 25 Gbps up to potentially 40 Gbps, and meets 100 Gbps Ethernet (4×25 Gbps) and 100 Gbps 4X InfiniBand Enhanced Data Rate (EDR) requirements. There are many products with QSFP28 form… Read More
