8-to-1 Cable Aggregator DB78 Male to 8x DB25 Female Fan-Out Octopus Cable
This is an unbranded 8-to-1 fan-out aggregator cable, sometimes called an octopus or breakout cable, that connects a single 78-pin DB78 male connector to eight individual DB25 female connectors. This type of cable is used to interface a multi-port serial controller or multiplexer card — which presents a single high-density connector on its back panel — to up to eight individual RS-232 serial devices or terminals. The cable allows a single card slot to serve multiple serial connections simultaneously.

Applications
Fan-out aggregator cables like this one are commonly used with multi-port serial controller cards and asynchronous serial multiplexers in server, workstation, and industrial computing environments. The DB78 high-density connector became a standard back-panel interface on 8-port and 16-port RS-232 serial cards — manufacturers such as Digi International, Moxa, Lantronix, and various OEM card makers used this connector style to pack multiple serial ports into a single card slot. Each DB25 female leg on this cable connects to one RS-232 device: a terminal, modem, POS system, industrial controller, or other serial peripheral. These cables date primarily from the 1990s and early 2000s when RS-232 serial connectivity was a dominant interface in data centers, point-of-sale systems, and industrial automation. While RS-232 has largely been supplanted by USB and Ethernet in consumer applications, it remains in active use in industrial, medical, and legacy system environments where multi-port serial cards are still standard equipment.
This 8-to-1 DB78 to DB25 fan-out aggregator cable has been inspected and is in good used condition. It was pulled from a working environment where it was actively in use. The cable jacket and connectors show normal age-related wear consistent with previous service. All eight DB25 female fan-out legs and the DB78 male single-end connector appear intact with no visible damage to the pins or housings. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
