Typical applications include SDH Multiplexer systems or ATM-switch and IP-router equipment supporting SDH physical interfaces. The SFP-155E™ module is fully interchangeable with STM-1 or OC-3 optical SFP modules and provides system developers an easy migration to STM-1 electrical interfaces. With the availability of the SFP-155E™ module, any system that already supports STM-1 optical SFP, can now also support STM-1 electrical. The development effort is minimized and a quick time-to-market solution is guaranteed. A single card design can support optical and electrical STM-1 interfaces, resulting in increased flexibility for the equipment user and reduced inventory and spare counts. Changing between optical and electrical STM-1 interfaces can be done in the field to optimize the system port-types to the application, while the system is in operation.
The SFP-155E™ can be used with industry standard coaxial cables and connectors, provided there is 2 mm spacing between adjacent modules.
