Raytrans 16E1 SDH Optical Terminal Features and Applications

The Raytrans 16E1 SDH Optical Terminal is a multi-service STM-1 level SDH optical terminal built on SDH and EOS technologies, fully compliant with ITU-T standards. The SDH Optical Terminal provides users with access and transmission of multiple services. It offers two 155.52Mbps optical interfaces (A and B), four 10M/100M physically isolated Ethernet interfaces, supports up to 24 shared 10M/100M Ethernet interfaces, and 16 groups of E1 interfaces. It features ITU-T G.813 standard network element timing, VC-12 cross-connection, and channel protection functions. Additionally, the IDM MSTP155-16 can serve as an add-drop multiplexer or terminal multiplexer for building point-to-point, point-to-multipoint chain, and ring transmission networks. The Raytrans 16E1 SDH Optical Terminal is widely applicable in telecom data services, power, banking, public security, military, and other sectors for public telephone network access or dedicated line information transmission.

The Raytrans 16E1 SDH Optical Terminal adopts a 19-inch 1U standard chassis structure for easy installation. The SDH Optical Terminal integrates SDH, PDH, and IP access functions to meet most remote service access requirements. The SDH Optical Terminal supports 3 service slots, accommodating E1 service boards, FXS/FXO boards, V.24/V.35 boards, Ethernet expansion cards, video cards, and universal service boards for flexible configuration as needed. The SDH Optical Terminal features multiple clock modes to meet clock requirements in various application environments, including local crystal oscillator clock, line-extracted clock, and external clock 2MBIT/2MHZ. The SDH Optical Terminal provides comprehensive monitoring and alarm functions. Panel indicators display specific alarm statuses, and the device can output alarm information. The SDH Optical Terminal offers dual optical or dual electrical SDH interfaces for easy construction of chain or redundant ring topologies. The SDH equipment supports point-to-point, chain, and ring networking, and can also be jointly networked with centralized MSTP systems. The cross-connection capacity is 252×252 VC-12. In optical port mode, FC/SFP optical modules are available. It can interconnect with the STM-1 optical interfaces of any standard SDH/MSTP equipment. The SDH Optical Terminal supports DC-48V, AC220V power supply, or dual power options.
