OC-3/STM-1 Coax-to Fiber Distance Extension

The following application shows a typical SDH/SONET network where the SDH/SONET Add/Drop multiplexers drop off STM-1 (OC-3) coax or fiber to customer premises. The SDH/SONET routers at the end of each drop utilize coax interfaces.

The diagram depicts two applications of the iConverter STM1 copper-to-fiber media converter.

In the case of a coax drop from the network (a), two converters are used to convert the coax to fiber, and then back to coax for connection to the router. The use of the media converters allows the STM-1 electrical signal to reach far beyond the distance limitations of the coax.

In the case of a fiber drop from the network (b), a single converter is used to convert the optical fiber to coax, for connection to the router.
