The transceivers may be used for other applications at
signaling rates outside of the 10 MBd to 125 MBd range
with some penalty in the link optical power budget
primarily caused by a reduction of receiver sensitivity.
Figure 5 gives an indication of the typical performance
of these 1300 nm products at different rates.
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.
Transceiver Jitter Performance
The Avago Technologies 1300 nm transceivers are
designed to operate per the system jitter allocations
stated in Table E1 of Annex E of the FDDI PMD and
LCF-PMD standards.
The Avago Technologies 1300 nm transmitters will
tolerate the worst case input electrical jitter allowed in
these tables without violating the worst case output
jitter requirements of Sections 8.1 Active Output
Interface of the FDDI PMD and LCF-PMD standards.
