What is the maximum supported distance for 100G Transceivers and Cables?

The maximum currently supported distance for 100G is 40km with a CFP2 form factor and 10km with the QSFP form factor. Additional optics may be released in the future to support longer distances.

What is QSFP28?

QSFP 40 GB Transceiver

The Quad Small Form-factor Pluggable (QSFP) is a compact, hot-pluggabletransceiver used for data communications applications.

The form factor and electrical interface are specified by a multi-source agreement (MSA) under the auspices of the Small Form Factor Committee. It interfaces networking hardware to a fiber optic cable or active or passive electrical copper connection. It is an industry format jointly developed and supported by many network component vendors, allowing data rates from 4×10 Gbit/s. The format specification is evolving to enable higher data rates; as of May 2013, highest possible rate is 4×28 Gbit/s (also known as QSFP28).

12-Fiber MPO Cabling System

MPO fiber cables and related factors are now widely deployed in high speed fiber optic transmission system. MPO cables really provide great performance during 40G and 100G transmission over both short and long transmission lengths. But there are so many types of MPO components like MPO cables, MPO cassettes, MPO adapters, MPO patch panels, and so on And all of these products are usable in different MPO polarity types. Customers can get confused easily by these MPO products.

In gain, unlike traditional duplex transmission on two fibers or BiDi transmission over a single fiber, the MPO system transmits optical signal over 12, 24 or more fibers at the same time. More fibers and cables are applied in the MPO cabling system. Thus, technicians in a data center or server room are even facing a headache problem which is MPO cable management. This post is to provide the details of a commonly used MPO cabling system-12-fiber MPO cable system for better understanding, selecting and management of MPO products.
