In order to reduce the cost of interconnecting between high speed optical equipments, optical internetworking forum had made a serial of implementation agreements of optic interlink within very short distance, namely VSR interface agreements. Its key intention is to replace high speed serial parallel optic link with low-speed parallel optic link for lower costs. VSR is a kind of physics layers transmitting technology. At present, OIF had put forward VSR interface implementation agreements of 10Gbit/s and 40Gbit/s.

为了降低不同设备间采用高速光互联的成本，光互连论坛(Optical Internetworking Forum，OIF)制订了一系列应用于甚短距离(very short reach，VSR)光互联的协议，也即是VSR接口协议，其核心是采用低速并行光链路代替高速串行的光链路，以降低成本。
