iConverter Single-Fiber CWDM Multiplexers and Add/Drop

MUX/DEMUX and Optical Add/Drop Mux Modules

iConverter Single-Fiber Course Wave Division Multiplexing (CWDM) modules provide a flexible and cost effective solution for increasing fiber capacity over single fiber networks. CWDM over single-fiber increases network bandwidth capacity by enabling multiple wavelengths, or data channels that carry independent services over existing fiber infrastructure.

iConverter Single-Fiber Course Wave Division Multiplexing (CWDM) modules provide a flexible and cost effective solution for increasing fiber capacity over single fiber networks. CWDM over single-fiber increases network bandwidth capacity by enabling multiple wavelengths, or data channels that carry independent services over existing fiber infrastructure. Up to eight separate data channels can be transported on a singlefiber link with iConverter Single-Fiber CWDM modules.

 

Single-Fiber CWDM/X Multiplexer/Demultiplexer Modules

Single-Fiber iConverter CWDM/X modules are available in 2, 4 and 5-Channel models, supporting a variety of wavelength combinations and port configurations.

The figure above shows a pair of 2-Channel, single-fiber CWDM/X modules that operate using the 1550nm, 1570nm, 1590nm and 1610nm wavelengths. Note that each wavelength is unidirectional and only flows in one direction. The channel ports of iConverter CWDM/X model 8872 receive 1570nm and 1610nm, while the channel ports of model 8873 receive 1550nm and 1590nm.

The 5-Channel Single-Fiber CWDM/X modules support five bidirectional wavelengths channels between 1431nm to 1611nm in 20nm increments with a 1310nm Pass Band Port. An optional Optical Time Domain Reflectometer (OTDR) port is available which provides the ability to test the integrity of the fiber optic link without disturbing the wavelength channels.

The 5-Channel Single-fiber CWDM models also support up to ten unidirectional data channels for data/video overlay networks.

Single-Fiber CWDM/AD Add & Drop Multiplexers

iConverter 1-Channel Single-Fiber CWDM/AD modules are Course Wave Division Multiplexing (CWDM) Optical Add and Drop Multiplexers (OADM). The CWDM/AD modules add (multiplex) and drop (de-multiplex) one channel on both directions of a CWDM single-fiber route. Nine standard models of the 1-Channel Single-Fiber CWDM/AD modules are available.

 iConverter CWDM/AD modules add new access points anywhere on a single-fiber CWDM network, without impacting the remaining channels traversing the network. Access points can be added to linear, bus, and ring networks, where the dualdirection ring design provides redundant protected architecture.

Chassis Options

The small and compact size of the CWDM modules yields one of the highest port densities in the industry. Using the 2U high iConverter compact chassis, up to 38 CWDM modules can be installed. They can also be installed in any iConverter chassis.

Since the iConverter CWDM modules are passive devices that require no external power, they can be installed in any OmniLight™ chassis using the LGX Adapter bracket.

OmniLight LGX Chassis

 

In this application, 1-Channel SF OADMs and a 4-Channel SF MUX/DEMUX module creates a linear network dropping services off to four sites on a single-fiber common link.

At the headend, a 4-Channel single-fiber MUX/DEMUX is used to connect four Ethernet switches each supporting two wavelengths over a common fiber link. At the first site, a 1-Channel OADM is installed to remove and add the 1470/1490nm wavelength which is associated with Network A. The remaining wavelengths (1510/1530nm, 1550/1570nm and 1590/1610nm) are passed through the OADM to the next site.

The 1510/1530nm wavelength associated with Network B is dropped at the second site while the 1550/1570nm and 1590/1610nm wavelengths are passed on to the last two sites. The 1550/1570nm wavelength associate with Network C is dropped at the third site and the 1590/1610nm wavelength is dropped at the last site.

 CWDM_Single-Fiber_App.jpg

CWDM technology provides the flexibility to increase capacity of existing fiber infrastructure by enabling multiple channels (wavelengths) over the same fiber cabling. Each channel carries data independently from each other, allowing network designers to transport different data rates and protocols (T1, T3, Ethernet, Serial, etc) for different customers or applications.

The wavelengths used with CWDM implementations are defined by the International Telecommunications Union, reference ITU-T G.694.2, listing eighteen wavelengths from 1270nm to 1610nm with 20nm wavelength spacing.

ITU-T G.652 single-mode fiber optic cable is not optimized for CWDM applications due to the high attenuation around the water peak region centered at 1383nm (wavelengths between 1390nm and 1410nm). When using the 1390 and 1410 wavelengths, the water peak attenuation should be factored into the design before implementing.

* Note: The ITU standard specifies the exact center wavelength as 1271nm, 1291nm, 1311nm, etc. However, for clarity (and to comply with general industry conventions) this data sheet refers to these wavelengths as 1270nm, 1290nm, 1310nm, etc.
