xPON network description
PON (Passive optical networks) it is a set of quickly developing perspective technologies of broadband multiservice access via optical fiber.The core of PON technology is that, its distribution network is built withoutusing of active components:optical signal splitting on one fiber optical line is realized with splitters. Structure of any passive optical network consists of three basic elements: OLT (optical line terminal), passive optical splitters and ONT (optical network terminal).OLT provides PON network interaction with internal networks. Splitters perform splitting of optical signal on PON. ONT has all required subscriber interfaces. PONarchitec...
CaTV services over PON network
When building PON network based on equipment produced by Eltex Enterprise LTD, providers can provide cable television services (analog or digital) by one cable along with data transmission on different wavelength. Data transmission is realized on 1490nm/1310nm wavelength to/from subscriber correspondingly, but cable television signal is transmitted on 1550nm wavelength. At the same time CaTV signal coming to ONT (NTE-2c, NTE-RG-1402GC and so on) is given by triplexer and output to RF port to which TV set is connected via coaxial cable. Advantages saving of investments on optical cable; convenience for subscr...
PON network deployment model
One of PON network deployment variant based on equipment produced by Eltex Enterprise LTD (OLT)LTE-8ST and ONT NTE-2, NTE-RG series, represents a topology, where each LAN port of subscriber terminal is used for definite service providing. Servers are located on provider`s network and operate on leased VLAN. VlanA – intended for IP telephony service arrangement; VlanB – intended for data transmission (Internet); VlanC – intended for IPMulticast packets transmission; VlanD – intended for Set-Top-Box control (middleware and monitoring); VlanE – used for control of subscriber terminals (TR-069) an...
