This is a cost-effective access technology that provides a reliable and scalable network for triple-play service applications, such as HDTV, IPTV, voice-over-IP (VoIP), and multimedia.

The CS-6300 series is a high-density chassis switch system equipped with 3 or 6 modular slots and redundant power supplies. By offering a variety of combinable management and switching modules, it provides exceptional deployment flexibility for network configurations. For example, the CS-6303R can support up to three CS6-16PON4C4S4X GPON modules, while the CS-6306R can accommodate up to six CS6-16PON4C4S4X GPON modules. Once fully equipped, the maximum number of functional ports is as follows:  

 Carrier-Grade Reliability and Flexibility

The CS-6300 Series is positioned as a core-layer GPON chassis switch. When paired with the CS6-16PON4C4S4X GPON module, it offers advanced intelligence and security features, along with high performance and flexibility. Key components of the CS-6300 Series include the management module, GPON OLT module, power system, fan system, and a redundant power design. All system modules support hot-swapping and seamless failover without manual intervention, making it ideal for large-scale networks and IP metropolitan area networks.

High Split Ratio for a Cost-effective Network Solution

The CS6-16PON4C4S4X GPON module is an ideal solution for FTTx applications. It helps to minimize the investment cost for carriers by offering a high split ratio of 1:128 per port and supporting the usage of PLANET ONUs. The CS6-16PON4C4S4X GPON module provides strong functionalities for Ethernet features such as VLAN, Dynamic Bandwidth Allocation (DBA), Service Level Agreement (SLA) and Access Control List. GPON protocol allows a Gigabit Ethernet communications fiber to be shared by multiple end users using a passive optical splitter.

Flexible and Extendable 10Gb Ethernet Solution

Every CS6-16PON4C4S4X GPON module has four 10G SFP+ uplink ports to deliver ultra-high-speed networking over long distances to service providers. Each of the 10G SFP+ slots supports dual speed and 10GBASE-SR/LR or 1000BASE-SX/LX. With its 4 ports, 10G Ethernet link capability and additional 4-port 1G Ethernet link capability, the administrator now can flexibly choose the suitable SFP/SFP+ transceiver according to the transmission distance or the transmission speed required to extend the network efficiently. The CS6-16PON4C4S4X provides broad bandwidth and powerful processing capacity for FTTx applications for distribution data link.

Layer 3 Routing Support

The CS6-16PON4C4S4X GPON OLT module enables the administrator to conveniently boost network efficiency by configuring Layer 3 static routing manually, the RIP (Routing Information Protocol) or OSPF (Open Shortest Path First) settings automatically. 

• The RIP can employ the hop count as a routing metric and prevent routing loops by implementing a limit on the number of hops allowed in a path from the source to a destination. 
• The OSPF is an interior dynamic routing protocol for autonomous system based on link-state. The protocol creates a link-state database by exchanging link-states among Layer 3 switches, and then uses the Shortest Path First algorithm to generate a route table based on that database.

Robust Layer 2 Features

The CS6-16PON4C4S4X GPON OLT module can be programmed for basic switch management functions such as port speed configuration, port aggregation, VLAN, Spanning Tree Protocol, WRR, bandwidth control and IGMP snooping. It also supports 802.1Q tagged VLAN, Q-in-Q and GVRP Protocol. In addition, the number of VLAN interfaces is 4K. By supporting port aggregation, the OLT allows the operation of a high-speed trunk combined with multiple ports. It enables up to 32 groups for trunking with a maximum of 8 ports for each group.

Efficient and Secure Management

For efficient management, the CS6-16PON4C4S4X GPON OLT module is equipped with console, Web and SNMP management interfaces. 

• With the built-in Web-based management interface, the chassis switch offers an easy-to-use, platform-independent management and configuration facility. 
• For text-based management, it can be accessed via Telnet and the console port. 
• For standard-based monitor and management software, it offers SNMPv3 connection which encrypts the packet content at each session for secure remote management.

Moreover, the chassis switches offers secure remote management by supporting SSHv2, TLSv1.0 and SSLv3 connection which encrypts the packet content at each session.

Extractive Power Supply Design for Enhanced Flexibility

The CS-6300 series is equipped with an extractable 100–240V AC power supply unit, making it easy for users to replace the power module. Additionally, the chassis switch reserves two extra backup power slots on the front panel, allowing users to install a second AC or DC power supply for redundancy. The AC and DC power options are interchangeable. The redundant power system is specifically designed to meet the demands of high-tech facilities requiring maximum power integrity.
