MCF-i ühendamiseks on vaja mitte ainult ujuvat mehhanismi, vaid ka pöördenurga täpset joondamist ümber kiu telje. Oldhami haakeseadis on mehhanism, mis rahuldab need vastuolulised tingimused ja mida on pikka aega kasutatud masinaehituse valdkonnas. Selle siduri ülesanne on pöördenurga täpne edastamine ka võlli ekstsentrilisuse esinemisel, kuid vastupidi, võlli ekstsentrilisus ilmneb ka siis, kui see ei pöörle, seega on võimalik täita MCF-pistikute jaoks vajalikud tingimused.
The first practical optical connector for MCF was the MU-type MCF connector developed in Japan in 2012 (Figure 1). By applying Oldham's coupling mechanism, positioning accuracy, including rotation angle, is maintained. It has the property that the connection loss does not fluctuate even when a tensile load is applied to the cable. The SC-type MCF connector was developed in 2019 to achieve the same principle with a simplified structure (Figure 1). The practical application of optical connectors to optical communication networks using MCF is progressing.
