Secure Uni-Directional, Simplex Cable/Links

Starting in software version 6.3.00 on the GigaVUE HC Series and GigaVUE TA series, 40/100/400Gb network ports are enhanced to support secure uni-directional, simplex cable/links between network and tool/hybrid ports.

Normal 40/100/400Gb link negotiation requires bi-directional signals, which is not allowed in some highly secure organizations that require isolation of data through unidirectional links.

Uni-directional, simplex cable contains fiber strands for one direction of traffic flow. Data flows in one direction only with no physical path in the cable for the other direction. Setting the port to forcelinkup forces the network port up into an RX-only mode and ignores link-based errors caused by the simplex cabling.

For the port command, refer to port. For show command output, refer to Displaying Ports Configured with Uni-Directional, Simplex Cable/Links.

From software version 5.12.00, GigaVUE‑HC3 node equipped with Control Card version 2 (CCv2) and its line cards such as ; SMT-HC3-C05, PRT-HC3-C08Q08, PRT-HC3-C16 will also support secure uni-directional, simplex cable/links in network ports at 100 G speed.

From software version 6.3.00, GigaVUE‑HC3 node equipped with Control Card version 2 (CCv2) and its line card SMT-HC3-C08, GigaVUE-HC1, GigaVUE-HC1P, GigaVUE-HC2P, GigaVUE-TA200, GigaVUE-TA200E, GigaVUE-TA25, GigaVUE-TA25E, GigaVUE-TA400 will also support secure uni-directional, simplex cable/links in network ports at 40/100/400 G speed.

Note:  40G SR/LR and 100G SR /LR optics are qualified with simplex cable on all the supported platforms. 400G DR4, 400G DR4+, and 400G FR4 optics are qualified with simplex cable on GigaVUE‑TA400.
