xWDM Technology
Wavelength Division Multiplexing (WDM) technology multiplies fiber capacity by multiplexing optical light signals of different wavelengths onto a single optical fiber. The technology is well standardized in the ITU G.695 and G.694 recommendations and widely used in datacom and telecom networks.

Passive Filters
Mux/Demux: A Mux/Demux unit terminates all wavelengths on the WDM system and is at the heart of point-to-point connections, The optical combining and splitting of wavelengths is a passive technology and a Mux/Demux unit requires neither electrical power nor software resulting in greatly increased reliability.

OADM: An Optical Add/Drop Multiplexer (OADM) unit terminates a limited subset of wavelengths in WDM systems. OADMs typically add/drop 1, 2 or 4 wavelengths and the remaining wavelengths are bypassed (expressed) through the fiber. It is possible to reuse the terminated wavelengths on the remaining span.

Due to the physical nature of light, the signals on WDM wavelengths are completely independent from each other and data streams with different line-rates and protocols can be transported on a single fiber or fiber pair. Traditional telecom signals (PDH, SDH/SONET), IP data (Ethernet, Gigabit Ethernet or 10G Ethernet) and storage data (8G/4G/2G/1G Fibre Channel) can therefore be transported over a single infrastructure without complex protocol conversion technologies To build a passive WDM system, two types of components are required:

CWDM and DWDM
WDM comes in two flavours; CWDM and DWDM Coarse WDM is a robust technology able to create 18 independent channels and was first to adapt a transceiver footprint. The CWDM channel spacing is 20 nm and a specific color coding is used which enables simple industry standard setup procedures. CWDM is typically used for un-amplified transmission up to 200 km.

At WareX we think of High-Performance Computing (HPC) as the interconnection of many compute, storage and networking systems that unlock high levels of computational capabilities for the hardest mathematical problems. Whether its weather-forecasting, biotech simulations, seismic data analysis or big data analytics, the interconnection of many individual devices using high-speed fiber optics provides value greater than the sum of the parts.

WareX provides fiber optic interconnects for HPC. Our products span a wide range of solutions from Active Optical Cables (for ease of use), to high-bandwidth pluggable transceivers (for greatest flexibility). Common across all our products is the continual evolution of bandwidth density and lowest power per bit, without compromising quality, reliability and supply.

Expanding business internet services, cloud computing, mobile bandwidth and residential gigabit broadband services are all driving the need for higher bandwidth while pushing fiber closer to the customer premises. To meet these demands, Operators must continuously upgrade and add capacities to their existing fixed-line access networks (e.g. VDSL, Cable Broadband and PON), while supporting legacy Customer Premises Equipment (CPE). To support long term growth, Operators continue to look for higher data rates, more scalable and higher-density next-generation access solutions such as 10G PON, NGPON2, and RF-over-Fiber, to name a few.

WareX offers a broad portfolio of optical components to support access network upgrades, including EPON/GPON, legacy SONET/SDH (OC-3/STM1, OC-12/STM4, OC-48/STM-16), Fast Ethernet, Gigibit Ethernet, and 10 Gigabit Ethernet. Products are available in form factors including SFP, SFP+, XFP . WareX products are designed to optimize fiber usage such as CWDM/DWDM SFP and Bidirectional (BiDi) SFP+ modules. In addition, WareX delivers cost-effective high speed, tunable components and bidirectional module technology that enable network consolidation, scalability for continuous network expansion and better bandwidth efficiency required for next generation access networks

WareX is a supplier of optical transceivers for a wide array of industrial applications. Harsh environments present a number of challenges for networking devices, including wide temperature variations, dust, vibration and shock. Often electromagnetic interference prevents the reliable transmission of data over copper wiring, and noisy or dangerous voltage environments necessitate the strict isolation of equipment. Fiber optics technology provides a reliable solution for data transmission in these environments.

As the industrial shop floor becomes more connected and Ethernet or IP networking becomes more ubiquitous, your choice in fiber optics technology and supply becomes more critical. WareX industrial solutions build upon the same technology building blocks that have been developed for our Ethernet and Fibre Channel products over decades of operation. Ruggedized form factors, wide operating temperature ranges and more stringent quality requirements ensure our fiber optic components and modules work reliably in the harshest of environments.

The data center landscape is changing rapidly. Broad investments are driving demand for new optical modules to address the needs of increasing bandwidth, lower power and longer reach. Significantly more fiber is being deployed today than ever before. Data rates of 10 Gb/s and higher are now commonplace in the modern data center, easily exceeding the capability of electrical interconnects on copper cabling. The data center market now demands access to a broad portfolio of fiber optic modules to connect servers, switches and storage.

Multimode Fiber (MMF) continues to provide the lowest cost and lowest power connectivity with trouble-free handling for the majority of data center deployments for links up to 300 meters. Active Optical Cables represent a simple, low cost interconnect for short reach interfaces less than 20 meters.

Single Mode Fiber (SMF) is preferred for longer reaches application , WareX offers a broad portfolio of products ,These fiber optic solutions are suited for applications within the datacenter, as well as for longer distances bridging one data center to another. These products span 10G Ethernet, 40G Ethernet and 100G Ethernet over reaches from 2-10km to 80km in form factors such as SFP+, QSFP+,CFP2, X2 and XFP.

The rapid scaling of data center infrastructure to meet the needs of consumers and enterprise cloud services requires a supplier that can ramp production to meet sudden-order demands, without compromising quality or reliability. For optical interconnects, trust WareX as your partner to help you meet your datacenter needs.
