Coarse wavelength-division multiplexing (CWDM) is used to increase the bandwidth of an optical fiber by multiplexing several wavelengths (or colors) onto it—just like dense wavelength-division multiplexing (DWDM).

Fiber-enabled global transformation

DWDM increases the bandwidth of an optical fiber by multiplexing several wavelengths(or colors) onto it. Even though it costs more than CWDM, it is currently the most popular WDM technology because it offers the most capacity.

Assessing Ethernet business services, from turn-up testing, to baselining, troubleshooting, monitoring and SLA conformance.

When it comes to high-speed transmission, especially when transmitting at 10G, 40G/100G, assessing fiber quality is a must. Once the basic parameters (i.e., loss, ORL, etc.) are under control, the next step is to qualify the fiber and to ensure that it is fit for transporting actual customer traffic. Polarization-mode dispersion (PMD) and chromatic dispersion (CD) optical testing become crucial at high speeds.

Stay in control of your fiber optic network's availability and quality. Always.

Learn all about fiber testing and ensure your network has the basics covered to deliver high reliability and availability to your customers.

DSL still remains the most widely deployed broadband access technology across the globe to bring triple-play services to business and residential customers. For many, the copper plant is the only economical basis for broadband, high-value service delivery that is still competitive.

Deploy and activate FTTx (FTTH, FTTA FTTB and FTTC) successfully—the first time—and maintain networks effectively

High-speed technology is complex, testing shouldn’t be

Fiber optic link characterization and troubleshooting

Following the FTTH trend to deliver more bandwidth to the consumers, a new technology is rising to provide more bandwidth, more services and future-proof networks to the enterprises: passive optical LAN (POL). Also called OLAN or fiber-to-the-desktop, this GPON-based technology creates a very cost-effective local area network (LAN) with virtually unlimited capabilities.

Get your network ready for next-gen PON. Make sure field crews see and test through the complexity.
