1. Type A connection

One end of Type A MPO/MTP patch cord is A-B normal patch cord, the other end A-A. Between MPO/MTP patch cord and normal patch cord is Type A MPO/MTP cassette and Type A MPO/MTP adapter (The two keys of type A adapter is opposite levels)

2. Type B connection

Both ends of Type B MPO/MTP patch cord are A-B normal patch cord. Between MPO/MTP patch cord and normal patch cord is Type B MPO/MTP cassette and Type B MPO/MTP adapter (The two keys of type B adapter is same level)

3. Type C connection

Both ends of Type C MPO/MTP patch cord are A-B normal patch cord. Between MPO/MTP patch cord and normal patch cord is Type A MPO/MTP cassette and Type A MPO/MTP adapter (The two keys of type A adapter is opposite levels)

All kinds of duplex patch cables and MPO patch cables are available and in stock for same-day shipping in OEMfibers.com.

The CFP module is a hot pluggable form factor designed for optical networking applications. CFP is acronym from 100G (C = 100 in Roman numerals; Centum) Form factor Pluggable. As name suggests, CFP is introduced to serve as optical transceiver for 100G interfaces. There are several CFP types introduced – CFP, CFP2 and CFP4, but let’s begin with general CFP architecture. General CFP architecture of CFP divides in two parts – Electrical interface interacting with equipment line card interface and optical line interface.

From equipment line card electrical interface aspect CFP has several “M-Lines” with are working 10Gbps speed and separate management interface used for clock & signaling data. If CFP is working 100GBase-LR4 mode, then it has 10 x 10Gbps M-Lines, if 40GBase-LR4 mode, then 4 x 10Gbps M-Lines. So called “Gear Box” is electrical 10:4 Mux/DeMux module aggregating up to 10 M-Line interfaces in maximum 4 N-Line interfaces. In case of 100GBase-LR4 each N-Line speed is 25Gbps and in case of 40GBase-LR4 N-Line speed is 10Gbps. Each N-Line is converted to optical signal with different wavelength and all four wavelengths are transmitted to CFP line interface using built in passive optical multiplexers.

CFP form factor is oldest from CFP family and it has current MSA (Multi Source Agreement) Rev 1.4. It can support both – 100GBase-X and 40GBase-X, and it’s general principle is following:

CFP electrical interface for 100G transmission is called CAUI – C (it again represents Roman Centum for 100G) Attachment Unit Interface. CAUI interface was standardized by IEEE802.3ba – Annex 83A, defining that CAUI interface is a parallel electrical interface with each lane running at a nominal rate of 10.3125 Gbps.

The 802.3bm standard was approved. The 802.3bm standard specifies four-lane chip-to-module and chip-to-chip electrical specification (CAUI-4). In new version of CAUI-4 interface are 4 M-Lines, each running speeds 25.78 Gbps for 100G Ethernet and 27.95 Gbps for SONET/SDH OTU4.
