Features: Download DOC:EPON C1500 ◇ IEEE802.3ah compatible ◇ 8 downstream PON ports ◇ 32 optical branches per OLT port for connection of up to 32 ONUs ◇ Downstream transmission up to 20kilometers ◇ 256 subscribers served in one compact 1U chassis ◇ Advanced L2/L3 switching and routing functions ◇ Remote provisioning and management ◇ Advanced security via Access Control List(ACL) ◇ Support unblocked wire speed forwarding ◇ Support TCP/IP, ICMP, ARP, OSPF, BGP, RIP, PIM-SM, PIM-DM, IGMP protocol Description The GEPON system uses a single optical fiber for both upstream and downstream transmission. Downstream traffic is sent via 1490nm wavelength and upstream traffic uses the 1310nm wavelength. The 1550nm wavelength is reserved for future CATV or wavelength division multiplex (WDM) upgrading. It is a fiber to the Home (FTTH) platform providing up to 1Gb/s Ethernet data and optionally video and voice on IP(VOIP)services to commercial and residential end users.
