10 Gigabit Small Form Factor Pluggable (XFP) was developed under the
Multi Source Agreement (MSA) Group.
The XFP MSA Group created the specification for the XFP module. The standard includes a cage design,
the form factor, and IC interfaces.
The 10 Gbit XFP module converts serial electrical signals to external serial optical or electrical
signals. The XFP module is hot pluggable.
The XFP module supports SONET [OC192/STM-64], 10G Fibre Channel, G.709, and
10Gigabit Ethernet with the same
module.
The XFP electrical port has one Differential Transmit port [TX], one
differential Receive port [RX], a differential Referential clock [RefCK],
and other additional control signals.
The TX and RX lines are CML interfaces, the RefCK lines are PECL, and the control/status lines are
LVTTL interfaces.
The out going LVTTL lines require a 4.7k ohm resistor pull-up. I/O ground
signals are isolated from the case.
A 2-wire I2C interface is also included [SDA/SCL]. The
LVTTL interfaces operate off of 3.3 volts.
The XFP modules uses 3 different power supplies; 1.8v, 3.3v, 5 volts, and an optional -5.2 volts.
Transmitter Jitter: Total Jitter [TJ] is defined at 0.30 UI (p-p) maximum.
Deterministic Jitter is defined at 0.15UI (p-p) maximum.
Receiver Jitter: Total Jitter is defined at 0.65UI (p-p) maximum.
Total non-data dependent jitter [DDJ] is defined at 0.45 UI (p-p) maximum.
