Alloptic Ge-PON (Gigabit Ethernet Passive Optic Network)

One of our core products is Alloptic’s Symmetrical Ge-PON (Gigabit Ethernet Passive Optical Network) FTTP technology. FTTP (Fiber to the premises) technology brings one optic fiber into the customer’s premises and provides triple play services (Video, Audio, Data) at gigabit speeds to the end user. This technology is a thousand times faster than existing DSL or cable connections and is virtually limitless when it comes to future expansion. The Alloptic Gigabit Ethernet PON solution is based on IEEE TCP/IP standards, which with the advent of the personal computer and the Internet, has become the fastest growing technology of choice for the future. Alloptic’s Ge-PON technology is based on open IEEE standards and not on proprietary protocols, which means Alloptic’s product is compatible with third party Ge-PON equipment.

Alloptic’s Ge-PON system does however offer some very unique features that are not found on other Ge-PON systems, which sets it apart from competing Ge-PON systems. Features like field-hardened ONU’s, TDM voice with E1/T1 ONU ports, variable packet lengths, special traffic handling for IPTV, internal SIP and TDM codecs.

What does Alloptic’s Ge-PON give you?

In short - everything! On a single fiber optic, we can supply all the telecommunications into a business or home that you will ever need. This technology is ideal for deployment in gated communities, office parks and even mining environments. Alloptic’s products is successfully replacing legacy copper networks on a daily basis in brown-field sites. The following services can be supplied to a premises (single home, apartment, business, site etc):

• Secure LAN / WAN / Internet service over standard 10/100 or Gigabit Ethernet ports
• VoIP service with guaranteed QOS (Quality of service) with built-in SIP ATA
• TDM (Not VoIP) Telephone service over standard telephone (POTS) ports with built-in TDM service
• Business telephone service over E1 ports (Basic rate or primary rate ISDN / E1)
• IP-Television service over standard Ethernet ports that hook up to IP Set-Top-Boxes (STB’s)
• Video on Demand (VoD) service over standard Ethernet ports in conjunction with IP-Television service
• Terrestrial television (UHF and VHF) signal service over coax port
• Satellite service over coax port, both Single L-Band and full transparent Quad L-Band service
• Secure and guaranteed QoS (Quality of Service) IP-CCTV service with IP-video codecs over standard Ethernet ports
• Private VLAN services between business users
• Low headend cost sue to Alloptic’s common privatized VLANs per service, which still allows VLAN QoS
• Electricity and water meter reading over standard Ethernet ports

All of this over one single fiber that runs into one field- hardened ONU in the customers premises or on the Curb.

The Structure of Alloptic’s Ge-PON network

Ge-PON networks are Point-To-Multipoint fiber-optic networks utilizing multiple optic wavelengths to convey services in both directions. Convergence of communication happens at the head-end chassis (Alloptic’s EdgeGEAR models). In a gated community this would be some central equipment room where the outside communication technologies are routed to. This could be Primary rate or basic rate E1 or ISDN lines, VSAT or direct data links, satellite television feeds or terrestrial antenna television signals. There is typically also a PBX or VoIP Server (VoIP PBX) at the head-end. There could also be IP-TV equipment and Video on demand servers (VOD) at this location. All the different services are tied into the head-end chassis. From there a single optic fiber is routed to a particular area where it is spliced directly onto a tiny passive optic splitter (the size of a splice protector or about 4cm long and less than 5mm thick). The splitter requires no power and is spliced directly onto the fiber. It requires no special housing other than what would normally be needed for a fiber splice. Form there, the fiber is split up to 32 ways to a drop fiber that goes directly to each ONU at the customer premises where all the services are made available on the ONU’s ports

So this looks nice, but does it actually work?

And the answer is - absolutely yes!. Alloptic has the largest number of GePON deployments in the world today. And we are not talking about demo or small trial systems, we are talking about real systems in full daily operation. Not only in the rest of the world, but here in Africa as well. Alloptic was the first in Africa with a working system operated by Terracom in Rwanda. In South Africa, Alloptic was also first to install a fully working FTTB system at Lonmin Platinum in the North West province. More recently, Alloptic systems were also successfully deployed in Mozambique, Musina, Delmas and Umhlanga.

Why GE-PON?

Alloptic’s GePON system is based on IEEE network standards for Gigabit Ethernet Passive Optic Networks. Why GePON? - the reason is simple: Ethernet technology is the fastest growing network communications technology today. Not only is it becoming exponentially faster by an order of magnitude every other year, it is also getting cheaper every year. In 1981 Ethernet started off at 1Mbps, but quickly moved to 10Mbps. By 1983 the ISO adopted the 100Mbps standard and its popularity has resulted in a flurry of activity to push its capabilities even further. We now have Gigabit and even 10 Gbps Ethernet. There are dozens of companies producing standards based ethernet chips world wide. The worlds largest manufacturer of exported electronic goods, China, has also standardised on GePON technology. They now have 3 different standards based GePON vendors, meaning that you will in the near future be able to purchase ONU’s from these low cost manufacturers that will be interoperable with the Alloptic GePON architecture. There are other standards when it comes to PON systems - there are BPON systems as well as GPON systems. Unfortunately BPON and GPON capable products contain ATM technology, the chips or Intellectual property of which is extremely expensive, since traditionally ATM is only used in legacy core telco networks, meaning that it is rapidly diminishing in popularity.
