NOTE
If tabular report is desired, use technique of (42)(c) above for
option desired.
(43) Repeat technique of 7l above and set Index of Refraction to Customer Existing
value recorded on data sheet.
(44) Set TI ON-OFF switch to OFF.
CAUTION
DO NOT remove optical modules with power on or damage to
optical module may occur.
(45) Remove TD-260C optical module and install TD-261C optical module in TI.
(46) Remove FOCUS-SWCM from test setup and install FOCUS-LWCM (fig. 3)
(47) Set FOCUS-LWCM WAVELENGTH switch to 1300 nm.
NOTE
FOCUS-LWCM nominal wavelength is actually 1310 nm when
WAVELENGTH switch is set to 1300 nm. WAVELENGTH
switch nomenclature was changed during manufacture of this
test equipment. Slight wavelength difference between TI and
FOCUS produces negligible effect on measurements.
(48) Set lightwave multimeter to measure optical power in dBm at 1300 nm.
(49) Set ON-OF switch to ON.
TD-261C optical module.
(51) Repeat technique of 7l above and set Index of Refraction to Customer Existing
value recorded on data sheet.
(52) Set ON-OFF switch to OFF.
(53) Remove TD-261C optical module and install TD-285C optical module in TI.
(54) Set ON-OFF switch to ON.
(55) Set TI wavelength to 1310 nm as required by pressing softkey next to λ: on TI
display.
(56) Set lightwave multimeter to measure optical power in dBm at 1310 nm.
