The Series Smart Cassette EPON OLT are the high-integration and medium-capacity cassette and They are designed for operators’ access and enterprise campus network. It follows the IEEE802.3 ah technical standards and meets the EPON OLT equipment requirements of YD/T 1945-2006 Technical requirements for access network——based on Ethernet Passive Optical Network (EPON) and China telecom EPON technical requirements 3.0. EPON OLT possesses excellent openness, large capacity, high reliability, complete software function, efficient bandwidth utilization and Ethernet business support ability, widely applied to the operator front-end network coverage, private network construction, enterprise campus access and other access network construction.
The EPON OLT series provides 4/8/16 * downlink 1000M EPON ports, and other uplink ports. The height is only 1U for easy installation and space saving. It adopts the advanced technology, offering efficient EPON solution. Moreover, it saves a lot cost for operators for it can support different ONU hybrid networking.
