IEEE C37.94-2017 PDF
This standard describes the interconnection details for N × 64 kbps, where N = 1, 2…12, connections of teleprotection equipment to digital multiplexers using optical fiber. Requirements for both physical connection and the communications timing are also included.
The purpose of this standard is to allow the interconnection of different vendors’ teleprotection equipment with different vendors’ multiplexer equipment, without any restriction on the content of the N × 64 kbps data using up to 2 km of 50 μm or 62.5 μm multimode or up to 20 km of 9 μm single-mode optical fiber.
Revision Standard – Active. An optical interface for use between teleprotection and digital multiplexer equipment Keywords that can operate at a data rate of N × 64 kbps where N = 1, 2…12 is described in this standard. Requirements for both physical connection and the communications timing are also included.
