EPON OLT 2 PON ports and 4 uplink ports

EPON OLT 2 PON ports and 4 uplink ports

Features


  •  2 PON ports with 1490/1310 nm PON transceivers

  •  Distance till ONU's up to 20 km

  •  1:64 split ratio and 1:32 supported

  •  Up to 128 ONU's per OLT

  •  Features rich SNMP based EMS management

  •  Layer 2 Convergence Switch

  •  Rich selection of ONU types supported

SPOTLIGHT

EPON OLT with 2 ports & 4 uplink ports - 2 SFP and 2 10/100/1000 UTP based, managed by EMS based on standard SNMP protocol.

Applications

Fiberbit's 2 PON port EPON OLT  get's installed in center - POP's and NOC's, where core IP and phone network connections are available. Connected with one side to splitters and subsequently to ONU's, and another side as an uplink to router and switch to Internet or WAN, this 2 port OLT provides you quick start of a network withough big investment in central POP equipment. You can start with 1 PON port, and later upgrade this OLT to 2 PON ports and 128 ONU's. It is worth to mention that you are not limited to connect only 1 subscriber to each ONU - Fiberbit have a wide selection of multiport ONU's, such as 4, 8 and even 24 ports. This gives you a bigger freedom to plan network. Applications currently covered by EPON is:

  • Small and mid sized and big ISP's;

  • Regional level carriers who want to organize fast development of FTTH access

  • Hotels and resorts who want to establish triple play over a fiber

  • Local Area Networks;

  • CCTV IP camera surveillance 


Below you can see 1 common scenario -  suburban household connected by EPON OLT in center and various ONU's at the CPE - user side.

EPON OLT suburban scenario
Description
2 PON port EPON OLT optical line terminal equipment. It can support 2 GEPON PON ports and connect 128 ONU at most (by 1:64 splitter), and provides 2 uplink GE optic SFP slots and 2 uplink copper SFP slots. This type EPON OLT also have built-in powerful switch modules, supporting full-duplex forwarding, powerful layer-2 protocols.

Main distinction, besides the long list of sophisticated features, that you can review below, we can mention EMS system. Some screenshots are provided below.

EPON OLT EMS system

In EPON system, EPON OLT units PON port is responsible for the registering of ONU, transfers the Ethernet message received from network in the downlink to EPON optical signal, and sent it to ONU by passive network. In up link, it receives EPON optical signal sent by ONU and transfer it to ethernet message then send to swich core equipment. It includes 2 PON port of 1.25G; usually each PON port can access 64 pieces of ONU equipment in the transmission distance of 10kms or 32 for 20 km The equipment is composed by high integrated OLT chips and independent control modules, offering reliable assurance for users in functions and performance.

Modern networks rarely rely on pure topologies like bus, ring, or star. Most common solutions use hybrid topologies, which are combinations of features from those three.   Star-Wired Ring As it is clear from the name, star-wired ring topology has features of star and ring topologies. You can see example of this topology ...
