Single-mode Fiber to Ethernet media converter with ST connector

Hi,

We have a setup with
Procurve Switch >> Ethernet >> (ST) Media Converter >> Single Mode Fiber run >> (ST) Media Converter >> Ethernet >> Procurve Switch

This links a building which is at the end of our playing field.

Media Converter is a Arcutronix EX 100-S (http://www.fibre.co.uk/uploads/DS-EDX100-S_new.pdf)

I would like to replace this with the 1GB converter, however I can only find one with the SC connector. Is there a 1GB converter that has ST connector ?

​

Any help would be much appreciated, thank you.
