With 10G and 25G Ethernet tools coexisting available today, we might frequently encounter the compatibility issues linked to SFP+ and SFP28 form factors. Anyway, the newer 25GbE technologies are backward compatible with 10GbE, allowing customers to build and cross-connect a heterogeneous-speed Ethernet network. Here we list the faqs coming through average customers.

1.What's the difference between SFP28 and SFP+?

The pinouts of SFP28 and SFP+ connectors are mating compatible. However, SFP+ is made to operate at increase to 10 Gb/s whereas SFP28 can handle 25Gbps, 10Gbps and even 1Gbps. SFP28 has increased bandwidth, superior impedance control and less crosstalk compared to the SFP+ solution. Besides, the SFP28 copper cable offers considerably greater bandwidth and lower loss when compared to SFP+ version.

2.Can the SFP28 be used in SFP+ slot, and what speed will I get?

Theoretically, plugging an SFP28 transceiver or cable into the 10G interface can be simple for certain devices to get 10Gb/s data rate, but this solution isn't recommended, because it will be tied to the NIC and switch port that you have. Only once your SFP28 module is 100% compatible together with your server or switch is it possible to ensure that the links can go seamlessly and efficiently.

3.Can the SFP+ be utilized in SFP28 slot, and what speed am i going to get?

Theoretically, plugging an SFP+ transceiver or cable in to the 25G SFP28 slot is feasible. Nevertheless, you also need to ensure make sure that your existing modules will be appropriate for your switch gear. In other words, although a switch that accepts the SFP28 form factor can physically accept a SFP+ connector in the same port, it doesn’t imply that your SFP+ modules will continue to work on your own equipment.

The performance of optical fiber connectors, we ought to first consideration the optical properties, furthermore to taking into consideration the interchangeability, repeatability, tensile strength, temperature and mating cycles.

(1) Optical properties: optical performance requirements for fiber optic connectors , mainly insertion loss and return lack of both of these basic parameters.

The insertion loss (InsertionLoss) connection loss, refers to the effective optical power loss because of the import of the connector link. Insertion loss no more than possible, the overall requirements shouldn't be higher than 0.5dB.

Return Loss (ReturnLoss, ReflectionLoss) identifies the suppression of the connector to link optical power reflection, the normal value shouldn't be less than 25dB. The request of the connector, the pin surface after a particular polishing allows greater return loss is generally not less than 45dB.

(2) Interchangeability, repeatability The fiber optic connector is a common passive devices, for the same kind of fiber optic connectors, can generally be any mixture of uses, and can be utilized repeatedly, which to import the excess loss is normally in the number of significantly less than 0.2dB.

(3) Tensile strength to accomplish fiber optic connectors, and general requirements for the tensile strength ought to be no less than 90N.

(4) Temperature General requirements, fiber optic connectors should be temperature-40oC to 70oC the standard use.

(5) Mating cycles At the moment, the fiber optic connectors Could be inserted and grab over l000 times.

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.
