HSP Optical line terminal with PDH multiplexer

 Optical line terminal with PDH multiplexer


          SparkLight is a compact, powerful, highdensity and user-friendly, next generation SDH multiservice node for provisioning of PCM (voice, data), PDH (E1, E3), SDH (STM- 1, STM-4, STM-16) and Ethernet (FE, GbE) over SDH/xWDM. 
          SparkLight HSP is a compact, powerful, user-friendly and easy to install device for providing PDH (E1, E3) and Ethernet over optical fibers, that enables service providers to offer subscribers reliable, high-performance, high-speed communications services such as LAN interconnection, Internet access, voice & data services, etc. Any combination of up to 40xE1, up to 4xE3 and up to 2xEthernet (10/100BaseT/ X) is possible in common capacity 72xE1 equivalent.
