The Dense Wave Multiplexing DWDM channel or light wavelength matrix (please see chart below) has brought tremendous benefit to the metropolitan and long haul data transmission world.
Bandwidth hungry applications are requiring more information over the same transport infrastructure with the explosive growth of the internet. With CWDM and DWDM Optics, the carrying capacity of the physical medium (fiber) is increased because each DWDM/CWDM channel is transmitted at a different frequency. Many engineers refer to this as the ‘rainbow’ of light, where each channels represents a color of light available within or over the medium (fiber).
DWDM also has the ability to amplify all the wavelengths at the same moment, without first having to convert them to electrical signals, as well as the ability to carry signals of different speeds and types simultaneously over the medium (fiber). This is called protocol and bit rate independence.
DWDM is a big winner in the Metropolitan backbone. It is fast and flexible in the provisioning of protocol- and bit rate-transparent, data centric, protected services, and has the ability to offer new and higher speed services at less cost.
The key requirements for DWDM systems in the Metropolitan area include: Multi-protocol support, cost effectiveness, reliability and availability, openness (interfaces, network management, standard fiber types, electromagnetic compatibility, ease of installation and management, size and power consumption, and scalability.
Overall, the technical advantages to DWDM (Bandwidth Aside) are: DYNAMIC PROVISIONING (Provides engineers the ability to provision in days, not months, because of its fast and simple connections), SCALABILITY (DWDM leverages the available dark fiber to meet the demand for capacity on point to point links and existing SONET/SDH rings), and TRANSPARANCY (It can transparently support TDM and data formats such as Gigabit Ethernet, ATM, ESCON, and fiber channel wit open interfaces over a common physical layer.
DWDM enables a large savings on regenerators (RPTR) and amplifier infrastructure compared to the typical SONET/SDH optical networks, greatly reducing up front infrastructure cost barriers. Besides the lowered infrastructure cost benefit, the DWDM systems have simplified the of network capacity by problem in many ways.

Shipping
Lately, we have been getting a lot of questions about international shipping so we've decided to post some of the answers right here. Read on to find out just how easy it is to get quality optical transceivers either shipped directly to you or drop shipped to a location of your choice.
We at Approved Networks, Inc. take pride in our highly flexible logistics capability. Drop shipping to international and multi-site locations is a daily occurrence at our facility. Our shipments test and ship the same day the order is received, unless the order is received past 3pm Pacific, but we will most certainly try to get it out if that’s needed. Larger shipments of 1000+ optics can sometimes take a day or so to test and ship, but nevertheless, we do pride ourselves in the ability to ship product faster than anyone in our industry. Typically the optics are at your site waiting for the switches/routers to be delivered. Besides your typical clear channel 1000base through 100G receivers, we pride ourselves on the ability to quick-ship channel specific DWDM and CWDM product. The channel just can’t compete with our ability to direct support and price colored optics.

The international shipping capability of our
on-line check out process makes drop shipping to most world locations
easy. Any VAT or tariff pricing, along with the chosen shipping
charge according to your delivery needs, is added and the summation price is typically
well below the in-country OEM cost for the same optics by the OEM. We not
only save the largest domestic end users in the world by drop-shipping to
multiple locations, but we also support non-U.S. Headquartered companies
directly.
Approved leverages every major shipping
company (Fed Ex, UPS, DHL, and others) in order to calculate the best price for
our customers. Although we always send a tracking number to the
recipient when product is shipped, many of our customers prefer that we use
their shipper number so that everything is reported on their internal shipping
ledger. Approved has shipped to the most remote areas of Africa, Asia,
and Latin America, bringing ‘light’ to the most rural areas and the largest
companies in the world.
Approved Networks Inc. takes pride in its
ability to ship and track multiple orders. Please let us know if you have
any questions regarding our logistics. Call: 800.590.9535
