What does SFP+ stand for?

Small Form-Factor Pluggable Plus. It is the second generation of the SFP interconnect systems designed for 10G performance.

What is your standard turn around time for delivery?

F2H Store carries high levels of inventory on standard lengths (0.5m, 1m, 1.5m, 2m, 2.5m, 3m, and 5m). Other lengths are available in 3 to 5 days.

Do you offer custom EEPROM programming?

Yes, upon request. Cables with custom EEPROMs will be supplied under a different part number.

What product documentation do you offer?

Product specification sheets, customer use drawings, signal integrity reports, 3rd party interoperability reports and EEPROM content tables are available on our website.

Do you have design qualification test data?

Yes, mechanical and electrical test data is available upon request.

Do you offer production test data?

We can provide production test data for insertion loss and return loss, NEXT and FEXT upon request. Standard production testing includes insertion loss and return loss. All test data is stored by cable serial number.

What are the other key product attributes?

Our automated termination process insures our cable assemblies exhibit best in class impedance and cross talk performance.

What cable jacket color is available?

Standard jacket color is black. Red, white and blue jackets are also available.

Where are these cable assemblies used?

These are “point-to-point” cables that are used to directly connect two pieces of active network equipment like switch-to-switch or switch-to-server applications. They are most commonly used in data centers for ToR (top of rack) or MoR (middle of rack) aka leaf-spine applications that require increased bandwidth.

Can I use SFP+ cables in SFP ports?

Yes, SFP+ cables are compatible to SFP ports and will work fine. SFP cables are not compatible to SFP+ ports. SFP cables can be plugged into SFP+ ports but they are not designed for 10Gb/s data rates.

What is the difference between SFP+ and SFP?

The pinouts of SFP and SFP+ connectors are identical. However, SFP has a maximum data rate of 5Gb/s whereas SFP+ is designed for 10Gb/s. The SFP receptacles and plugs are not as well impedance matched as SFP+ receptacles and plugs. Also SFP+ cable is designed for 10Gb/s whereas SFP cable may not be able to satisfactorily transmit that rate.

Do these products support 25G per lane data rate and for what standards?

Yes, per SFF-8402, SFF-8419, SFF-8432, SFF-8472 and IEEE 802.3by, these cables support 25G Ethernet

Do these products support 10G per lane data rate and for what standards?

Yes, per SFF-8431 and SFF-8083, these cables support 10G Ethernet, 8G FibreChannel, 10G FCoE, 10G InfiniBand and various unified architecture link applications.

Will these products support 25G per lane data rates?

Our SFP+ product will not support 25G per lane data rates. We currently offer SFP28 interconnect (25GBASE-CR) per the IEEE 802.3by specification
