&lt;p style=&quot;margin-bottom: 10px; font-family: Catamaran, sans-serif; font-size: 14px;&quot;&gt;BDCOM P3310B complies with IEEE802.3ah and P.R.C intercommunication standard, YD/T 1475-2006, supports CTC20/2.1, automatically discovers and cooperates with ONUs of different manufacturers.&lt;/p&gt;&lt;p style=&quot;margin-bottom: 10px; font-family: Catamaran, sans-serif; font-size: 14px;&quot;&gt;BDCOM P3310B OLT supports the symmetric uplink/downlink 1.25Gbps PON transmission rate, efficient bandwidth usage and Ethernet services, helping carriers to provide reliable services to their users.&lt;/p&gt;&lt;p style=&quot;margin-bottom: 10px; font-family: Catamaran, sans-serif; font-size: 14px;&quot;&gt;Its coupling ratio, 1:64, and its support of different hybrid ONU networks minimize the carrier’s investment.&lt;/p&gt;&lt;p style=&quot;margin-bottom: 10px; font-family: Catamaran, sans-serif; font-size: 14px;&quot;&gt;BDCOM P3310B, based on the edge-cutting technologies, is strong in functions. A few of its functions such as QoS guarantee, SLA and DBA can be easily listed out.&lt;/p&gt;&lt;p style=&quot;margin-bottom: 10px; font-family: Catamaran, sans-serif; font-size: 14px;&quot;&gt;BDCOM P3310B can support four PON systems and has the following advantages:&lt;/p&gt;&lt;p style=&quot;margin-bottom: 10px; font-family: Catamaran, sans-serif; font-size: 14px;&quot;&gt;EPON: P3310B supports IEEE802.3ah and PRC Community Industry Standard (YD/T 1475-2006). It adopts the point-to-multipoint network topology, effectively collects separate Ethernet services and aggregates them on the MAN node. It connects the upper-layer devices through the GE interface and can be connected to the existing network smoothly.&lt;/p&gt;&lt;p style=&quot;margin-bottom: 10px; font-family: Catamaran, sans-serif; font-size: 14px;&quot;&gt;The Dynamic Bandwidth Allocation (DBA) mechanism enables all users to share the 1Gbps bandwidth reasonably, guaranteeing a reliable QoS.&lt;/p&gt;&lt;p style=&quot;margin-bottom: 10px; font-family: Catamaran, sans-serif; font-size: 14px;&quot;&gt;System’s capacity: The modularized PON card of BDCOM P3310B can support four EPON systems simultaneously, up to 256 ONUs and the 1/64 coupling ratio.&lt;/p&gt;&lt;p style=&quot;margin-bottom: 10px; font-family: Catamaran, sans-serif; font-size: 14px;&quot;&gt;Uplink interface: Its flexible design supports various MAN interface type groups. The optical ports or the electrical ports are selected according to network conditions.&lt;/p&gt;
