4. Specification of Receiver

	Parameter		Symbol	Min.	Typ.	Max.	Unit	Note
Input Optical Wavelength			λIN	1480	1490	1500	nm	PIN-PD
Receiver Sensitivity			PIN			-26	dBm	Note (1)
Input Saturation Power (Overload)			PSAT	-3			dBm
Signal Detect -Assert Power			PA	-		-26	dBm
Signal Detect -Deassert Power			PD	-44			dBm	Note (2)
Signal Detect Hysteresis			PA-PD	0.5	2	6	dB
Data Output Rise/Fall time			tr/tf			260	ps	Note (3)
Receiver		1480 to 1500nm				-12	dB	Note (4)
Reflectance
Optical	Isolation	1260 to 1360nm				-43	dB
from	External	1550 to 1560nm				-33	dB
Source		1640 to 1665nm				-33	dB

Note (1). Measured with Light source +1dBm, 1490nm, ER=9dB; BER =<10-12@PRBS=27-1 NRZ This assurance should be met with asynchronous data flowing out of the optical transmitter of the system under test. The output data pattern from the transmitter of the system under test is a repetition of alternate 0/1 pattern as defined for this measurement.

Note (2). When SD deasserted, the data output is Low-level (fixed) Note (3). These are 20%~80% values.

Note (4). Measured at wavelength of 1490nm.
