Figure 3.    Low-Input Receiver, RF Output Level Compared to Transmitter OMI: Receiving Switch with 0 dB Setting 

 

1

 Receiver has a 2-position RF attenuator switch (-8 dB and 0 dB). For the standard receiver, the 0 dB setting is used for -6 to -2 

dBm optical input power, and the -8 dB setting is used for -2 to +2 dBm optical input power. For the low-input receiver, the 0 dB 
setting is used for -10 to -6 dBm optical input power, and the -8 dB setting is used for -6 to -2 dBm optical input power.

 These specifications apply to the forward receiver module only. They do not include frequency response contributions from the 

forward optical transmitter. 

3

 Optical output refers to a 1310-nm wavelength; for a 1550-nm wavelength, the output is ~1.1 V/mW. 

4

 This specification is the minimum receiver RF output level for the stated transmitter percentage OMI per channel, with the 

specified receiver optical input power and receiver attenuator setting. To determine RF output levels at other optical input power 
levels, add (or subtract) 2 dB in the RF level for each 1 dB increase (or decrease) in receiver optical input power.
