Description
MTP Conversion Cable Overview
MTP conversion cables, also known as conversion harness cables, are designed with the same fanout form as MTP breakout cables but differ in fiber counts and types. They are terminated with only MTP connectors on both ends, making it especially fit for high-density cabling. Specifically, they can be applied for 10G-40G, 40G-40G, 40G-100G, 40G-120G direct connections, which avoid fiber wasting and largely increase the capacity and flexibility of the existing base-12 and base-24 MTP cabling systems. Compared to purchase and install separate conversion cassettes, applying MTP conversion cables is a more cost-effective and lower-loss option.
MTP Conversion Cable Applications
1×2 MTP conversion cables, 1×3 MTP conversion cables, 2×3 MTP conversion cables are designed with different structures fit for diverse connections.
1×2 MTP Conversion Cable
This MTP conversion cable is terminated with a 24-fiber MTP connector on one end and two 12-fiber MTP connectors on the other end, which enables a base-24 MTP cable to be integrated into the existing base-12 backbone MTP links to carry the signals. The transmitted data are split equally across two 12-fiber previously installed within the MTP system. As shown in the figure below, the base-24 100G connection is converted into the 12-fiber MTP backbone trunks via 24-fiber to 2×12-fiber MTP conversion cables, so as to extend further value of the legacy infrastructures.
1×3 MTP Conversion Cable
This MTP conversion cable is terminated with a 24-fiber MTP connector on one end and three 8-fiber MTP connectors on the other end, which allows a base-24 backbone link to be converted into three base-8 cables so as to achieve 40G to 120G deployment. When connected to 40G, this conversion cable can create three 40G interfaces for QSFP+ modules, fully utilizing all the 24 fibers. Thus, three 40G dual-way transmissions are achieved in the existing 24-fiber MTP cable. In addition, 24-fiber to 3×8-fiber MTP conversion cables can be also used to break the 120G CXP module signals into three 40G QSFP+ links to realize the migration from 40G to 120G networking.
2×3 MTP Conversion Cable
This MTP conversion cable is terminated with two 12-fiber MTP connectors on one end and three 8-fiber MTP connectors on the other end, which allows converting the signals from three four-channel modules to two 12-fiber trunks and achieves full utilization of the 12-fiber system. 2x12-fiber to 3×8-fiber MTP conversion cables can be used for 10G-40G and 40G-40G connections. In 10G-40G connection, the three 8-fiber MTP connectors can be plugged into three 40G QSFP+ transceivers on the switch. And the two 12-fiber ends are terminated with a 2x12-MTP to 12x duplex LC cassette, converting the three 40G signals to 12 x10G signals.
As for the 40G-40G connection, the three 8-fiber MTP connectors of the 2×3 MTP conversion cable are linked to the three 40G QSFP+ transceivers on the switch. And the two 12-fiber MTP connectors of both two MTP conversion cables are plugged into MTP 12-fiber adapters. In this way, the Base-8 MTP links are able to transmit on the existing Base-12 cabling system to fully leverage the fiber resource.
