Receive Sensitivity
To meet short haul requirements, the XRT83SL314 can accept T1/E1/J1 signals that have been attenuated by
12dB of flat loss in E1 mode or by 655 feet of cable loss along with 6dB of flat loss in T1 mode. However, the
XRT83SL314 can tolerate cable loss and flat loss beyond the industry specifications. The receive sensitivity in
the short haul mode is approximately 4,000 feet without experiencing bit errors, LOF, pattern synchronization,
etc.
Although data integrity is maintained, the RLOS function (if enabled) will report an RLOS condition
according to the receiver loss of signal section in this datasheet. The test configuration for measuring the
receive sensitivity is shown in Figure 11.
