Transceiver Jitter
Performance
The Hewlett-Packard 1300 nm
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.
The HP 1300 nm transmitters will
tolerate the worst case input
electrical jitter allowed in Annex
B without violating the worst case
output optical jitter requirements.
The HP 1300 nm receivers will
tolerate the worst case input
optical jitter allowed in Annex B
without violating the worst case
output electrical jitter allowed.
The jitter specifications stated in
the following 1300 nm transceiver
specification tables are derived
from the values in Table B1 of
Annex B. They represent the
worst case jitter contribution that
the transceivers are allowed to
make to the overall system jitter
without violating the Annex B
allocation example. In practice,
the typical contribution of the HP
transceivers is well below these
maximum allowed amounts.
Recommended Handling
Precautions
Hewlett-Packard 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). The HFBR-5200 series of
transceivers meet MIL-STD-883C
Method 3015.4 Class 2 products.
Care should be used to avoid
shorting the receiver data or
signal detect outputs directly to
ground without proper current
limiting impedance.
Solder and Wash Process
Compatibility
The transceivers are delivered
with protective process plugs
inserted into the duplex SC or
duplex ST connector receptacle.
This process plug protects the
optical subassemblies during
wave solder and aqueous wash
processing and acts as a dust
cover during shipping.
These transceivers are compatible
with either industry standard
wave or hand solder processes.
