The Security Exhibition & Conference will be on in Sydney this year from 24 to 26 July and we are looking forward to exhibiting at the International Convention Centre, Sydney. Please come along to stand G52 to look at OSD’s latest industrial Ethernet transmission solutions ranging from Fast Ethernet to 10GbE and PoE up to 90W.

The OSD2892 is an industrial managed Layer 3 Ethernet Switch with 36x 10/100/1000BASE-T and 4x10G Trunk SFP ports. The OSD2892 is temperature rated from -20 to +75°C and is available in one of several powering options including dual redundant DC powering (10 – 36VDC @ 45VA Max), AC powering and dual redundant AC powering (90 – 264VAC @ 55VA Max)
A PoE version is also currently in development and will be released shortly.
The OSD2010 is a device used to convert between different fiber modes or operate as an optical repeater. The OSD2010 has two SFP ports which work in a “plug and play” operation, without the need for user settings. The device allows the user to introduce a CWDM to an existing fiber network. SFPs operating at up to 10Gbps may be used with the OSD2010.
The OSD2524 is an Industrial Managed Layer 2 Ethernet Switch with 20x 10/1000/1000BaseT, 4x RJ45/SFP Combo and 2x 1G Trunk SFP ports. The OSD2524 is temperature rated from -20 to +75°C and is available in one of several powering options, including dual redundant DC powering (10 – 36VDC @ 40VA Max), AC powering and dual redundant AC powering (90 – 264VAC @ 50VA Max).
A PoE version is also currently in development and will be released shortly.
Further to our last PoE Tech Note, this brief tech note discusses the current situation with PoE above 30W (or the IEEE802.3at standard).
Although there are many IP cameras requiring greater than 30W, there is no current standard for this. However, PoE++ is being ratified (perhaps late 2017) and will be known as IEEE802.3bt.
How will IEEEE802.3bt work?
IEEE802.3bt will support power over 4 pairs as well as single or dual signature PD operation. While PDs have operated with a single signature for PoE up to 30W, the new standard will also allow for dual signature detection where a PD derives power from two PSEs.
Currently all PoE++ implementations are flying in the dark to some extent: OSD has come across a number of different interpretations which need to be resolved, almost on a case by case basis.
OSD Approach to PoE++
OSD will continue to work with its customers in the supply of PoE operating at >30W and can support dual signature if required.
OSD currently uses Linear Technology chipsets which are widely accepted by most PDs.
OSD will offer IEEE802.3bt when it is ratified and this will include single and dual signature detection.
Thanks to all who attended OSD’s stand at Security 2017 in Sydney. It was great to have the exhibition in OSD’s hometown of Sydney however we will be off to Melbourne for next years event.
