4. Specification of Receiver

Parameter	Symbol	Min.	Typ.	Max.	Unit	Note
Input Optical Wavelength	λIN	1260		1360	nm	PIN-PD
Receiver Sensitivity	PIN			-31	dBm	Note (1)
Input Saturation Power (Overload)	PSAT	-3			dBm
LOS-Deassert Power	PA	-		-32	dBm
LOS-Assert Power	PD	-44			dBm	Note (2)
LOS Hysteresis	PA-PD	0.5	2	5	dB
Optical Reflectance				-14	dB	Note (3)
Output Data Rise/Fall time	tr/tf			1.5	ns	Note (4)
S/X Endurance				10	dB	Note (5)
Optical Isolation		25			dB	Note (6)

Note (1). Measured with 1520nm, ER=10dB; BER =<10-10@PRBS=223-1 NRZ Note (2). When LOS asserted, the data output is Low-level (fixed)

Note (3). When the terminal is viewed from the optical path, the reflection toward the optical path of the optical signal with a central wavelength of 1260nm to 1360nm transmitted to terminal.

Note (4). These are 20%~80% values

Note (5). X=10 MHz, Rectangular BER =10-10

Note (6). Receiver isolation between 1480nm ~1580nm
