The TE Connectivity (TE) SDH128A is a single-mode optical grid transformation array designed to be used in the networking and communication industries. It is a point-to-multipoint connectivity device with a drop-and-insert port that enables the establishment of a high-capacity link between multiple interconnected nodes. Its port capacity is 128 ports, with each port being able to provide data rates up to 12.5 Gbps. The SDH128A also features integrated digital signal processing (DSP) technology, allowing it to detect, monitor and protect signals of various types while ensuring high data integrity in communication links. It also offers secure, standardized management protocol support (e.g. SNMP, DHCP, etc.) and a web-based interface for ease of use. The SDH128A is suitable for applications such as P2P (Point-to-Point) gigabit level access, data center node connection, or fast Ethernet access.
