Direct Connect/Fiber Conversion Application
This application shows two 10G switches with SFP+ ports in two different locations. The switches are connected via longhaul, single-mode fiber (>80km) with a pair of iConverter XG+ 8599R-01-AZ (SFP+to XFP) media converters. In the top location, a low-cost SFP+ Direct Attach Cable is used to connect the 10G switch port to the media converter because the distance is within the 10 meter limit of the Direct Attach Cable. In the bottom location, a pair of multimode SFP+ transceivers provide the connectivity between the media converters and the switches.
OTN Long-Haul DWDM Application
This application shows three 10G DWDM connections across an OTN network. Three iConverter XG+ modules with high-power XFPs are installed in a 5-Module Chassis and connected with fiber patch cables to DWDM Multiplexer. The iConverter XG+ modules function as fiber repeaters and wavelength transponders. The high-power XFPs perform Forward Error Correction on the incoming signal, then amplify and reencapsulate the outbound OTN signal.
iConverter XG+ and Tunable Transceivers
Tunable XFP transceivers are configurable to support a specific channel in a DWDM optical network. Tunable XFPs allow network operators to remotely change wavelengths (channel paths) when they need to redistribute bandwidth, or reconfigure/upgrade traffic patterns and services.
The iConverter XG+ management system supports the configuration of these tunable XFPs. When the XG+ is used in conjunction with an iConverter management module, it provides a user interface that allows the network operator to change the DWDM channel of the transceiver, eliminating the need to be physically on-site with external programming equipment.
In addition to changing the DWDM channel by specifying the wavelength or the transceiver-specific channel ID, the DWDM channel can be selected by inputting the industry-accepted ITU channel number.
Using tunable transceivers not only ensures quick responses to changes in network topology, it also lowers OpEx and CapEx by reducing truck rolls and eliminating up to hundreds of fixed-wavelength DWDM XFP transceivers from spares inventory.
