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.
