Project 8 - In 1999, Redfern Broadband Networks Pty Ltd (RBN) was foundedby Ross Halgren and Richard Lauder as part of the Redfern Photonics group of companies to capitalise on the expected capacity growth in optical metro and access networks. RBN's vision was the gradual replacement of legacy TDM and ATM protocols with Gigabit Ethernet over wavelengths. RBN was seed funded by Redfern Photonics to develop a first prototype GigaWave Enterprise DWDM platform supporting 8 x Gigabit Ethernet services on a single fibre strand. The demonstration of this platform at OFC'2000 in Baltimore and Supercom'2000 in Atlanta USA led to RBN's first major round of funding (US$28M) led by Optical Capital Group and development / marketing relationships with Corvis USA. The 8-DWDM wavelength GigaWave Enterprise and subsequent 64-DWDM wavelength GigaWave Metro platforms included several world firsts, such as an optical backplane that eliminated all the front-panel optical connectors, that for traditional fibre-optic platforms, had to be unplugged in order to replace a faulty line card. Another first (before Meriton Networks and Infinera) was the development of an Optical-Electrical-Optical (OEO) Switch Shelf for the GigaWave Metro platform with all-optical backplane interconnects between the GigaWave Line-Card & Trib-Card shelf, the OEO Switch Shelf and the DWDM Filter Shelf. The GigaWave Metro was therefore an OEO Reconfigurable Optical Add-Drop Multiplexer (ROADM). The GigaWave Enterprise Shelf included a built-in Craft Terminal using a VGA Graphics Interface Module and a Single-Board Computer running Linux OS. For the larger GigaWave Metro platform, 100BaseT management interfaces were used between the Management Shelf and the other active Equipment shelves. The GigaWave Metro was first demonstrated at Supercomm' 2001 in Atlanta. The demonstration included a 1-Rack Unit, 1-lambda Optical Add/Drop Multiplexer (OADM) and Gigabit Ethernet 3R Regenerator interface co-located on the World Wide Packets Ethernet Booth carrying Gigabit Ethernet around the GigaWave DWDM Ring, via the 7' high, GigaWave ROADM Rack located on the RBN Booth. The GigaWave fibre ring also went to the Corvis Booth in the next pavilion (thanks to Bell South contractors running the cable for RBN) where CCTV video cameras were installed and interfaced to the another GigaWave Mux co-located with Corvis's DWDM equipment. The video cameras were interfaced to the DWDM ring using Optical Systems Design (OSD) video modems and the clipped FM-modulated video transported over the GigaWave DWDM ring using 2R regeneration. The video channel was then demultiplexed, demodulated and shown on a video screen located on the RBN Booth.

Project 9 - Following the global optical market collapse in 2001, RBN responded accordingly to the changed market conditions and reduced its 7' high, 64 wavelength OEO ROADM prototype platform (the GigaWave Metro) to a low footprint, low power, extended temperature range CWDM ROADM called the GigaEdge 8200. Advanced Fibre Communications (AFC) and Marconi became US and global partners/resellers respectively of this high-functionality yet lower cost RBN product. For AFC, RBN rebadged the product as the TransMax1500. Sprint US standardised on the TransMax1500 for fibre backhauling their FTTN access networks comprising not just AFC DSLAMs but multiple different vendors DSL and POTS Multiplexer platforms fitted to the same or different cabinets in a FTTN backhaul CWDM ring. DSL platforms included the then-existing ATM-DSLAMs and new IP-DSLAMs with different CWDM wavelengths allocated to backaul each platform to the Central Office (CO) exchange. Due to the low first-in and incremental cost of the TransMax1500 compared to under-utilised DWDM platforms, Sprint and other Independent Operating Companies (IOCs) in the USA subsequently deployed the carrier-class TransMax1500 as an alternative or supplement to DWDM platforms for inter-office ring applications. For example, the TransMax1500 released six congested fibres carrying SONET OC48 traffic so that these fibres could then be redeployed for the new Gigabit Ethernet backhaul services or for facilitating a graceful DWDM network upgrade.

Project 10 - In 2005 a range of passive, low cost, extended temperature range, Single Fibre Working (SFW) filter modules were customised by Finisar for RBN so that customers could add/drop bi-directional CWDM channels between GigaEdge 8200 regenerator nodes. This complementary SFW CWDM platform was sold by RBN as the GigaEdge 6100 series. The GigaEdge 6100 tributary interfaces were then terminated by the GigaEdge 2300 muxponder/Mini-MSPP platform. Seamless GigaEdge 2300 - 6100 - 8200 network solutions were thus facilitated and Embarq were one of the lead customers for this integrated GigaEdge solution-set. In 2007, using this same solution set with a simple 6100 tributary port upgrade to support low reflectance SC/APC optical connectors, RBN supplied for a Ericsson US trial in Singapore, a CWDM PON overlay network that multiplexed 2 x Gigabit Ethernet (GbE) point-to-point services (using a pair of GigaEdge 2320s) with standard Ericsson GPON point-to-multipoint services and RFoG PayTV services on the same SFW passive-split (1:32) FTTP access network.
