Transceiver Signaling Operating  
Rate Range and BER Performance  
The transceivers may be used  
for other applications at  
signaling rates different than  
155 Mb/s with some variation  
in the link optical power  
budget. Figure 5 gives an  
indication of the typical  
performance of these products  
at different rates.  
Transceiver Jitter Performance  
The Agilent 1300 nm  
For purposes of definition, the  
symbol (Baud) rate, also called  
signaling rate, is the reciprocal  
of the symbol time. Data rate  
(bits/sec) is the symbol rate  
divided by the encoding factor  
used to encode the data  
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 Agilent 1300 nm  
transmitters will tolerate the  
worst case input electrical  
jitter allowed in Annex B  
without violating the worst  
case output jitter requirements.  
(symbols/bit).  
These transceivers can also be  
used for applications which  
require different Bit Error  
Rate (BER) performance.  
Figure 6 illustrates the typical  
trade-off between link BER  
and the receivers input optical  
power level.

the typical contribution of the  
Agilent transceivers is well  
below these maximum allowed  
amounts.
