Product Details

SFP-155E TM  – Electrical Pluggable Interface


The SFP-155ETM electrical transceiver offers full duplex STM-1 electrical (155 Mbit/s) SDH transport over

coaxial cables. The interface is fully compliant to ITU-T G.703 (ES1) signal specification. The module is

compatible with the SFP Multi-Source Agreement (MSA) standard. Typical applications include SDH Multiplexer systems or ATM-switch and IP-router equipment supporting SDH physical interfaces. The SFP-155ETM 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-155ETM module, any system that already supports STM-1/OC-3 optical SFPs 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-155ETM can be used with industry standard coaxial cables and connectors, provided there is 2 mm spacing between adjacent modules.
