Optics in Datacenter Interconnection

Fiber optics is no longer an optional technology, or only reserved for the toughest interconnect problems. Bandwidth, port density and low-power demands now require fiber optics. And fiber optics is now a pervasive, high-volume, low-cost set of technologies that make it an easy choice for switch interconnect and server I/O.

Etern Optoelectronics have the complete optics solution in transceiver and MPO cabling for datacenter interconnection, with scale production capacity, and years delivery experience.

The transceiver including 10G, 25G, 40G, 100G, 200G, 400G and beyond, applying in the first generation 40G, or mainstream 100G structure, or next generation 200G&400G structure datacenter. Scale production and delivery is Etern Optoelectronics advantage to meet customer demands. For more transceiver information, refer to: https://www.szetern.com/collections/transceiver

Three factors impact choosing the correct MPO cable for transceivers, keyway orientation, connector ‘gender’, and polarity. MPO transceivers have alignment pins built into the transceiver, therefore MPO connectors installed in transceiver must be ‘female.’ Additionally, MPO transceivers are also designed with the keyway on top, therefore any MPO cables plugged into transceivers must be the keyway up to ensure proper fiber handling and continuity.

MPO cable polarity is critical to connecting network elements. However, with three polarity options, choosing the correct MPO cable can be confusing to even the most seasoned of network professionals. These guidelines will assist in choosing the correct cable for the application, we mainly introduce two types polarity here.

Type A polarity

Application: Transceiver to MPO Adapter Panel

Type A, or direct Through, cables are configured in a keyway up to keyway down orientation so that each fiber (1, up to 24) from the transceiver will arrive at position 1, up to 24 on the other end.

Type B polarity

Application: Transceiver to Transceiver (8-fiber parallel transceivers 40G/100G, SR4, PSM4, and 16cores for next 200G&400G transceivers)

When directly connecting two transceivers to one another a Type B polarity MPO Cable is required. Type B cables cross over the fibers within the cable to ensure the Transceiver Tx and Rx are properly connected. Type B cables are configured keyway up to keyway up.
