A method of enabling transport of symmetric latency-sensitive constant-bit-rate (CBR) client data streams over an optical transport network (OTN) is provided. The method performs, utilizing an OTN wrapping device, an OTN wrapping operation on a received first constant-bit-rate (CBR) client data stream to form a first framed OTN data stream. The method determines a static wrapping delay induced on the first CBR client data stream by the OTN wrapping operation, performs, utilizing the OTN wrapping device, an OTN unwrapping operation on a received second framed OTN data stream to extract a second CBR client data stream from the second framed OTN data stream, determines a static unwrapping delay induced on the second framed OTN data stream by the OTN unwrapping operation, and equalizes the static wrapping and unwrapping delays by adjusting, at the OTN wrapping device, at least one of the static wrapping and unwrapping delays.
