Hong Kong Broadband Network Deploys Cisco ROADMs

Hong Kong Broadband Network (HKBN) is expanding its coverage and capacity with a Cisco IP Next Generation Network (IP NGN), using Cisco ROADM (Reconfigurable Optical Add/Drop Multiplexer) technology together with HKBN's existing ONS 15454 Multiservice Transport Platform (MSTP) optical core. The expanded optical core will assist HKBN in achieving its goals of increasing the scope of its service offerings and expanding its network coverage to 80% of homes in Hong Kong.


ROADM enables service providers to add, drop or pass through any combination of the available wavelengths by remote control without having to manually configure or adjust node configurations.


HKBN is the first service provider to deploy Cisco's ROADM. The deployment will start at the end of August and finish by early October. Upon completion, HKBN's optical core will consist of multiple rings spanning the territory of Hong Kong. The new network capacity will be about 2 Terabits.

  • In April, Hong Kong Broadband Network (HKBN) officially launched its 1 Gbps symmetric service for the residential market. Approximately 800,000 households, out of a total of 2.2 million households in Hong Kong, are wired to receive the service. The 1 Gbps symmetric service is priced at US$215 per month. HKBN noted that its 1 Gbps service is up to 166x faster downstream and 1,950x faster upstream than the advertised bandwidth of the incumbent's ADSL service. HKBN Premium bb1000 service is being offered on the same metro Ethernet infrastructure that delivers the company's Mass Market bb100 (symmetric 100 Mbps for US$34/month) and Entry Point bb10 (symmetric 10 Mbps for US$16/month) services.


  • HKBN is installing more than 10,000 Cisco Catalyst LAN switches and more than 800 Cisco routers in buildings throughout Hong Kong. Category 5e copper cables are wired from the LAN switch cabinet to the apartments of each target customer. Fiber-to-the-building (FTTB) was deployed between the buildings using the Cisco ONS 15454 Multiservice Transport Platform (MSTP) and Cisco Catalyst 4507R Switches.


  • HKBN is also using a Cisco Optical Core network. The deployment includes the Cisco ONS 15454 SONET/SDH Multiservice Provisioning Platform (MSPP); Cisco Catalyst 6500, Catalyst 4500, Catalyst 3350, and Catalyst 2950 series switches; and Cisco 2600XM Series routers. Cisco's ONS 15454 MSPP enables the carrier to converge its legacy voice and data services and a new pay-TV service into a single platform, and at the same time offer Layer 2 and 3 IP services using Resilient Packet Ring (RPR)-ready ML Series line cards. The network enables HKBN to deliver up to 200 digital pay-TV channels via MPEG-2 at 4.5 Mbps to 10 Mbps with DVD visual quality. Its service also features interactive pay-TV elements and enables PC or TV connection with the aid of a set-top box.
