Salira Optical Network Systems is supplying a “triple-play” optical network solution to GuangZhou Pantong Information Broadband Network (Panyu Cable), which provides cable TV and associated services to the Panyu district of the city of GuangZhou, China. The Ethernet, passive optical network (EPON) architecture is expected to scale to reach 260,000 endpoints and deliver 80 channels of broadcast TV, video on-demand (VOD), VoIP and high-speed Internet access.
Panyu will be using Salira’s 2500 optical line terminal, Salira 2300 multi-customer optical network unit and Salira Access Management (SAM) system, which combines service creation, subscriber management and EMS functionality. Salira’s ASIC driven platform allocates upstream and downstream bandwidth across the PON based on pre-defined class of service parameters at the port level, thereby enabling uniquely-defined SLAs for individual customers. The Salira 2500 supports up to 14 optical line cards or PON circuits. Each optical line card can support 16 Salira 2300s that can be located at up to 20 kilometers from the central office on the same PON. The Salira 2300 is configured with eight fixed 10/100 Mbps Fast Ethernet ports and two bays for modular plug-ins. One plug-in is configured with eight 10/100 Mbps Fast Ethernet ports, and another contains four T1/E1 ports. The Salira 2300 could be used to support multiple customers from the same PON termination.
Initially, Panyu will be using an RF video overlay design in which a separate wavelength is used to carry all TV channels directly to the ONUs. Coax cable inside the buildings carries the video to each apartment and subscribers use conventional set-top boxes to decode channels. In a later phase, Panyu plans to implement an IPTV architecture with IP multicasting occurring in the optical network.

- In July 2003, Salira announced that China Netcom Corporation is deploying its optical access platforms in Beijing and in Changsha City (Hunan province) to deliver advanced voice, video and data services to business customers in a variety of Fiber-to-the-Premises (FTTP) deployments. More specifically, China Network will use the Salira 2000 Platform to connect customers to existing SDH rings in order to deliver traditional E1 TDM services. China Netcom will also use the optical network for Layer Two Tunneling Protocol (L2TP) for VPN services, Video-on-Demand (VOD) and VoIP. Salira’s passive optical network (PON) architecture provides a 1:16 split.
- In October 2002, China’s Ministry of Information Industry (MII) certified the Salira platform for commercial deployment. The company has sales offices in Beijing, Shanghai, Chongqing and Shenzhen.
