Hello Wallace, product #FOTR-201 can test the dB loss directly and does not need a light source #FOPM-205 anymore. Thanks.

Hi! The Measurement Range of FOPM-205 @1550nm is -40dBm~+20dBm. -30dBm~+10dBm is Burst Measurement Range (1310nm Bursted Signal).

FOPM-205 is PON-specific power meter, which is different from basic optical power meters. It is specifically intended for FTTH and FTTP systems and can measure voice, data and video along a single fiber. It should be used with fiber optical light source at the other end.

1. FOPM-201 and FOPM-202 are the basic optical power meters, they can do some simple power tests. The main different of them is measurement range. 2. The basic functions of FOPM-203 and FOPM-204 are the same but their are measurement range are different. Compared to FOPM-201 and FOPM-202, FOPM-203 and FOPM-204 have switching measurement and value storage function. 3. FOPM-205 is PON-specific power meter, which is different from basic optical power meters. It is specifically intended for FTTH and FTTP systems and can measure all three signals (1310nm, 1490nm and 1550nm).

It can't be used with LC connector. It suit for SC/FC/ST.
