EIA/TIA-455-6B,
Method 1, 0-degrees:
Using a 7.5 c m [ 3 i n] mandrel
loc ated 23 cm [ 9 in] from behi nd
the back end of the module
assem bly, appl y a 2.2 N [0.5 l bf]
tensile load to eac h buffered or
coated fiber . Apply load at a r ate of
25.4 mm [ 1 in] per minut e at 0
degree pul l angle to the mated test
specimen. Hold for 5 seconds.
Measure att enuati on and r eturn
loss bef or e and after test.|Cable r etention, 90 degr ees.| Maxi mum attenuati on for any single
specimen is 0.75 dB befor e and
after test.
Minimum return loss f or any single
specimen is 20 dB after test.
Maxi mum attenuati on incr ease for|any single specimen is 0.5 dB after
test.

EIA/TIA-455-6B,
Method 1, 90-degrees:
Repeat cable retention t est with
tensile load appl ied at a 90- degr ee
pull angle.
Use 2.2 N [0. 5 lbf] tensi le load for
each buffer ed or c oated fiber when
testing the module assembly.
Durability. Maximum attenuation for any single
specimen is 0.75 dB befor e and
after test.
Minimum return loss f or any single
specimen is 20 dB after test.

EIA-455-21A.
Mate and unmate pl ug- to-jack
connect ion 500 t imes. Measure
att enuati on and r eturn loss before
and after test. Clean t he specimen
every 25 cycles. Record
att enuation every 50 cycles.
Record final readings af ter t he
specimens have been inspected
and cl eaned.

specimen is 0.75 dB befor e and
after test.
Minimum return loss f or any single
specimen is 20 dB after test.

Figure 2 apparatus.
Using a 7.5 c m [3 i n] mandrel,
apply a 224 g [0.5 lbf] tensi le load
to buffered or coated fiber at a
m inimum di stanc e of 20 cm [8 in]
behind the end of t he module
assem bly on the receive side of the
m ated specimen. Flex loaded side
± 90 degrees per cycle for 100
cycles at maxim um rate of 15
cycles per minute. Measure
att enuati on and r eturn loss before
and after test with the l oad
removed.
