10 Gigabit Fibre Channel [10GFC] is a point-to-point serial
bi-directional interface operating up to 10.2Gbps.
10 Gigabit Fibre Channel [10GFC] is an extension of the physical layer of Fibre Channel. 10GFC runs at 12.75GBd
[GigaBaud].
Communication is Asynchronous, Bi-Directional interface with a variable
frame length up to 2048 bytes, with a 24 byte header. Bytes are 10 bits
long, each forming a character, with 4 characters making a word
[Transmission Word]. CRC is used for error checking [Cyclic
Redundancy Check is the same 32-bit CRC used in FDDI]. Fibre Channel
uses 8B/10B
encoding (each 8 bit byte is translated into a 10 bit character in order
to equalize the numbers of 1's and 0's sent). Fibre Channel is primarily
used in high-end server SANs (storage-area networks). The Bit Error rate
[BER] is defined at 10-12.
The Electrical Interface [EL] uses ECL signaling levels via an unbalanced
75W line or a balanced 150W line(s).
The Optical uses: [LL]: long wave laser (1300 nm), [SL]: short wave laser
(780 nm), or [LE]: LED (1300 nm).
Fiber:
.. SC type connectors to IEC 61754-4-5
.. SG type connectors to EIA-604-7
.. LC type connectors to EIA-604-10
.. MT-RJ type connectors to EIA-604-12
Electrical unbalanced:
.. BNC, TNC type (style 1) connectors an for unbalanced 75W electrical interface to IEC 169-8, IEC 169-17

.. Electrical interfaces may use either or both style 1 and style 2
connectors. The cable will consist of TX+, TX-, RX+, RX- and a cable
shield.
Electrical balanced:
.. 9-Pin D-subminiature type (style 1) connectors an for balanced
75W electrical interface to IEC 807-3
..... Pinout for a 9-pin D Connector: Pin 1 TX+, Pin 6 TX-, Pin 5 RX+,
Pin 9 RX-, Shell Cable shield
.. 8-Pin (RJ-like) type (style 2) connectors an for balanced
75W electrical interface to IEC
61076-3-103
..... Pinout for an 8-Pin (RJ-like) Connector: Pin 1 TX+, Pin 3 TX-, Pin
6 RX-, Pin 8 RX+, Shell Cable shield

Fibre Channel uses three different topologies:
Point-To-Point; in which only two devices are directly connected
together.
Arbitrated Loop (FC-AL); with up to 127 devices on a single
network. Each device must arbitrate to grain access to the loop.
Fabric; The Switch used to interconnect the devices.
