Application of Mux/Demux in the field

GigaTech Products Multiplexer / Demultiplexer solutions utilize Wavelength Division Multiplexing (WDM) technology to allow bidirectional transfer of multiple data streams over a single fiber. Using either coarse or dense wavelength division multiplexing (CWDM or DWDM) a multitude of point source data streams can be aggregated to a single point of transmission and sent to another location. The network architecture benefits through the reduction of costly fiber runs and consolidation of network real estate.

CWDM (Coarse Wavelength Division Multiplexing)

Coarse Wavelength Division Multiplexing (CWDM) uses the wavelengths from 1270nm through 1610nm
with a channel spacing of 20nm. While CWDM cannot be amplified, these signals can be transmitted up to 80km with speeds up to 10G ethernet and 16G fiber channel, suitable for use in most metropolitan applications.

DWDM (Dense Wavelength Division Multiplexing)

Dense wavelength division multiplexing (DWDM) uses optical signals multiplexed within the 1550nm band using 0.8nm spacing. DWDM pluggable transceivers are capable of operating on 40 or 80 channels. Through the use of amplification, these signals can reach long haul transmissions of 1000km and above as well as speeds exceeding 100Gbps.

GigaTech Products utilizes the 100Ghz C-Band frequency range in the DWDM solutions allowing for up to 44 total DWDM spacings in each 1RU unit. Channels 1-72 are available through the 100GHz C Band spectrum, with C21-C60 being the most commonly used.

Industries that benefit from WDM

• Telecommunications

• Education

• Security / Surveillance

• Medical

• Corporate Infrastructure

• Data Centers

GigaTech Products and our reseller partner worked with United Regional Hospital to design a secure, custom dark fiber network enabling all facilities to connect to an off-site data center, offloading all mission critical applications and creating much-needed redundancy in information storage. Dark fiber also enables the hospital to continue to advance and implement technical solutions without having to secure more bandwidth to support new capabilities.

Using dark fiber to connect an existing facility to a datacenter 30km away

Goal: The hospital research facility needed to incorporate an off-site data center in order to further offload mission critical information, as well as establish priority redundancy in information technology and storage.

Solution: By incorporating DWDM technology, the facility was able to optimize the data transmission between locations without major capital expenditure. Designed to incorporate a maximum of 40 10G channels (400G worth of data) between a pair of fiber lines, the facility created enough resources for current to operations as well as allow for the potential for future growth.

By placing the transceiver ranges in the C band 100GHz (0.8nm spacing), there was enough room to incorporate 40 channels easily and effectively while avoiding crosstalk.

The transceivers transmit and power the laser from the host location, use the Mux/Demux boxes to package the information tightly in their specific wavelengths, and carry the data over long distance to be broken apart at the target location. This allows for data to be compacted and run 30km over a single pair of fibers.
