The following are publications that Haltec Enterprises' Director, Ross Halgren has authored, contributed to or been referenced by regarding innovative Research & Development activities.
Publication 1 - A Sydney University Electrical Engineering Undergraduate Honours Thesis called "Optical Fibre Communications System" was completed by Ross Halgren in 1976. See the Table of Contents (TOC) of the Thesis. This was the first thesis on optical fibre communications undertaken in this department. Twenty metres of 50/125 um multimode optical fibre for this thesis project work was donated by Dr Don Nicol from AWA Research Laboratories. It had been manufactured using their first generation horizontal fibre drawing machine. The Sydney University Optical Fibre Technology Centre (OFTC), which was pivotal to the formation of the Australian Photonics CRC, was established 15 years later, again with the support of Dr Don Nicol, who pulled the 2nd generation AWA fibre manufacturing equipment out of mothballs after it had been contributed by AWA into the OWA joint venture.
Publication 2 - The Sydney University Warren Centre project on Local Area Networks was the 2nd project overall and the 1st ICT project undertaken by the Centre. In 1983, Ross Halgren was seconded from AWA Communications Research Laboratory to the Warren Centre for 4 months to work full time as the Case Studies Group Leader for the Project under the direction of Dr John Limb. John was renowned for the prior R&D work that he had done on FASNET at Bell Labs and the LAN Project contributed to the design specification of AWA's integrated voice, data and video LAN product (AWANET). Ross was also one of the founding individual donors to the Warren Centre. See the Table of Contents (TOC) of the Report covering the sections contributed to.
3 - In 1990, a Masters of Engineering Thesis called "Optical
Fibre Distributed Access Transmission System" was completed
at the University of NSW by Ross Halgren. The Thesis covered 8
years of Research & Development from the initial Study Phase
through to the development of three products, OMM-2, AWANET and MILNET all of
which were based on the same core optical fibre communications technology developed
by Ross within the AWA Communications Research Laboratory. The Optical Multidrop
Modem (OMM-2) was developed as a dual-bus fibre backbone for Allen Bradley Programmable
Logic Controllers and was first installed as a 30km ring around Queensland International
Airport. AWANET was
developed as a dual-ring backbone for integrated Voice & Data Local Area
Networks and included both optical fibre and multi-pair electrical ring interface
cards. The first AWANET system was installed in the Sydney Police Centre and
2nd system was installed at RAAF Base Tindal. In the latter case, optical fibre
cable was installed for ring segments between buildings and multi-pair electrical
cable was installed for ring segments within each building. MILNET was
first designed as a 4th
Generation Combat System fibre-optic data bus for the new Collins
Class submarines but unfortunately it didn't get included in the winning tender.
It was subsequently upgraded to MILNET-2000, being a more generalised fibre-optic
backbone ring based on the emerging Fiber Distributed Data Interface (FDDI-2)
international standard and this was later deployed in various military communications
systems - some far beyond the author's original expectations (see MILNET-2000
Project 7). As part of the MILNET branch of the project, Ross
attended the ANSI X3T9.5 FDDI standards meetings in the US and influenced sections
of the FDDI-2 standard documents to meet the military application requirements
and wrote various application-oriented sections of the FDDI-2 standards.
