Twisted-Pair Cable/Connector Pin-Outs - HP J4865A Installation And Getting Started Manual

Fiber-Optic Cables
Port Type Cable Specifications
Gigabit-SX 62.5/125 mm or 50/125 m (core/cladding)
diameter, graded-index, low metal content,
multimode fiber-optic cables, complying
with the ITU-T G.651 and ISO/IEC 793-2 Type
A1b or A1a respectively.
Gigabit-LX 9/125 m (core/cladding) diameter, graded-
in1310 nm, low metal content, single mode
fiber-optic cables, complying with the ITU-T
G.652 and ISO/IEC 793-2 Type B1 standards.
OR
the multimode fiber-optic cables listed for
Gigabit-SX.
Note: To use multimode cables for Gigabit-LX, a mode conditioning patch cord may be needed - See the
Installation Guide that came with your module for more information.
Gigabit-LH 9/125 mm (core/cladding) diameter, graded-
in1310 nm, low metal content, single mode
fiber-optic cables, complying with the ITU-T
G.652 and ISO/IEC 793-2 Type B1 standards.
Note: Between the transmit and receive ends of the cable, at least 5db of attenuation is required for a
reliable connection. This is equivalent to 20Km of the fiber-optic cable. For distances less than 20Km,
you must add attenuators to bring the total attenuation to at least 5db. Most cable vendors carry
attenuators.

Twisted-Pair Cable/Connector Pin-Outs

The HP Auto-MDIX Feature:. In the default configuration, "Auto", the
10/100Base-TX ports on the 10/100-TX gl Module that is used in the Series
4100gl Switches all automatically detect the type of port on the connected
device and operate as either an MDI or MDI-X port, whichever is appropriate.
So for any connection, a straight-through twisted-pair cable can be used -- you
no longer have to use crossover cables, although crossover cables can also be
used for any of the connections. The 100/1000-T gl Module, and the
100/1000-T Transceiver supports the IEEE 802.3ab standard, which includes
the "Auto MDI/MDI-X" feature, which operates the same way.
