Answers

Q: What copper cable should I use to connect CX4 transceivers?
The CX4 interface uses the same physical connector as Infiniband, but Infiniband cables are not rated for the distances that CX4 can achieve. Users are advised to purchase CX4 cable assemblies that meet the IEEE CX4 specifications and support 10-Gigabit communication at distances up to 15 meters.

CX4 cables are factory-terminated and cable vendors offer them in various lengths. Some vendors who offer CX4 cables are:
Gore Electronics (www.goreelectronics.com) Non HP site
click on the "High Data Rate Copper" link
Molex (www.molex.com) Non HP site
search for "10Gbase-CX4"
Amphenol (www.cablesondemand.com) Non HP site
search for "CX4"
Leoni (www.leoni-telecom.com) Non HP site
search for "CX4"
click on the link with the words "Paralink cable assemblies"

Q: What fiber optic cabling should I use to connect CX4 media converters?
The CX4 Optical Media Converter (OMC) connects directly to the CX4 port, and a 12-strand multimode ribbon cable between OMCs supports 10-Gigabit communication at distances up to 300 meters, depending on the modal bandwidth of the fiber.

The 12-strand multimode ribbon cable can have either 62.5 or 50 micron cores, terminated by standard MTP™ (Multiple Terminations Push-pull Latch) connectors in a crossover configuration. Users should specify a "crossover" (often called "key up/key up") configuration for the ribbon cable. Also, specify Female-Female cables to connect to ProCurve 10-GbE CX4 Media Converters. The ribbon cables are known as MPO (Multi-fiber Push On) cables.

A vendor who offers MPO cables is:
Pro-Link LLC (www.dataaccessories.com) Non HP site
click on the link with the words "10GB Patch Cords",
then click on MTP Cable Assemblies
The MPO cables offered by Pro-Link LLC provide these modal bandwidths and distances:
Transceiver type Fiber type Core diameter (microns) Modal bandwidth (MHz*km) Supported range (meters)
CX4 Optical Media Converter multimode 62.5 150 1 to 50
CX4 Optical Media Converter multimode 50 500 1 to 100
CX4 Optical Media Converter multimode 50 2000 1 to 300


Q: Which type of fiber surface termination (finish/polish/endface) should I use for my patch cords?
To connect to ProCurve 10-GbE optical transceivers, use patchcords with UPC (Ultra Physical Contact) surface termination. The APC (Angled Physical Contact) termination is not recommended.



Q: Which ProCurve 10-GbE transceivers are supported in which ProCurve products?
The ProCurve Networking 10-GbE Transceiver Support Matrix specifies which 10-Gigabit transceivers are supported on which ProCurve products. General rules are:

  • only genuine ProCurve transceivers are supported on ProCurve products
  • when using the J8694A Switch yl 10-GbE 2-Port CX4 and 2-Port X2 Module, the J8439A CX4 Media Converter is supported on only the fixed CX4 ports


Q: What software versions are required to support the J8438A 10-GbE X2-SC ER Optic in ProCurve switches?
The J8438A is supported on all ProCurve switches that have X2 transceiver slots. For only the Series 3400cl and 6400cl Switches, software release M.08.75 or later is required to use the J8438A.



Q: What software versions are required to support the J8440B 10-GbE X2-CX4 Transceiver in ProCurve switches?
The J8440B (which replaces the J8440A) may require new software on the switch into which you install the transceiver. See the document titled Support for the J8440B 10-GbE X2-CX4 Transceiver for software requirements to use the J8440B transceiver in ProCurve switches.



Q: What software versions are required to support the J9144A 10-GbE X2-SC LRM Optic in ProCurve switches?
The document titled Support for the J9144A 10-GbE X2-SC LRM Optic specifies software requirements to use this 10-Gigabit optic in ProCurve switches. The document also identifies ProCurve switches and modules that do not support the J9144A ProCurve 10-GbE X2-SC LRM Optic.

Q: What preventive maintenance steps should I consider for my fiber optic cable ends and switch optics?
As transmission speeds increase over fiber optic cabling, dirt and debris on the connectors become more of an issue. A dirty fiber optic cable that works properly for 100 Megabit transmission might cause bit errors when the same cable is used for Gigabit or 10-Gigabit transmission. The document titled Preventive Maintenance of Fiber Optic Cables and Optics provides a set of recommendations for cleaning both the fiber optic cable ends and the switch optics to which the cables connect.
