Transceiver Jitter Performance
The Agilent 1300 nm
transceivers are allowed to make
to the overall system jitter
without violating the Annex B
allocation example. In practice,
the typical contribution of the
Agilent transceivers is well
below these maximum allowed
amounts.
transceivers are designed to
operate per the system jitter
allocations stated in Table B1 of
Annex B of the draft ANSI
T1E1.2 Revision 3 standard.

CENTER OF SYMBOL
The Agilent 1300 nm
transmitters will tolerate the
worst case input electrical jitter
allowed in Annex B without
violating the worst case output
optical jitter requirements.
Recommended Handling Precautions
Agilent recommends that normal
static precautions be taken in
the handling and assembly of
these transceivers to prevent
damage which may be induced
by electrostatic discharge (ESD).

Care should be used to avoid
shorting the receiver data or
signal detect outputs directly to
ground without proper current
limiting impedance.
The jitter specifications stated in
the following 1300 nm
