Optic al c ross-c onnec ts c onsist of a p reterminated  lig htg uid e shelf or Lig htg uid e 
Interc onnec t Unit (LIU) with lig htg uid e troug hs. A multi-mod e or sing le-mod e 
fib er op tic  c ab le c onnec ts the lig htwave transc eivers on the DEFINITY System to 
c onnec tor p anels insid e the shelf or LIU. Circ uits c an b e c hang ed  b y moving  the 
p atc h c ord  from 1 point on the c onnec tor p anel to another.
Measuring Single-Mode Power in the Field
The d ata pattern on the link influenc es the optic al p ower measurement. The d uty 
c yc le that the transc eiver is send ing  when the DEFINITY System is id le is a 30% 
on (“ 1” ) and  70% off (“ 0” ) d ata pattern. This imp lies that the op tic al read ing  will 
b e ab out 2.3d B less than the typ ic al outp ut p ower sp ec ific ation (-8d Bm). 
Calc ulate all p ower b ud get analysis at 50% d uty c yc le for both transmitter outp ut 
p ower and  receiver sensitivity. 
The following  information is p rovid ed  for field  troub leshooting  use only and  is not 
intend ed for fiber b ud g et analysis.
The p ower measurement is taken from the TX c onnec tor, through the entire fib er 
link, and  to the RX c onnec tor on the op p osite end  of the link (remote EPN). Refer 
to Fig ure A -2
 for a typ ic al fib er route.
1. Remove the fib er c ab le from the RX c onnec tor at the loc al 300A.
2. Attac h the p ower meter to the fib er c ab le. Note the read ing .
3. Reconnec t the RX c able. 
4. Rep eat the test at the RX c onnec tor at the remote 300A. Note the read ing .
5. Reconnec t the RX c able. 
6. Using Fig ure A -1
, d etermine the type of in-line attenuator req uired  for eac h 
d irec tion in the tested  fiber link.
NOTE:
Using the maximum power budget of 17dB in any fiber link may 
c ause p roblems if the fib er p lant is damag ed  and  ad ditional 
c onnec tors or sp lic es are ad d ed. Maintain a margin of at least 1d B; 
2d B is the ind ustry standard .

When to Use Single-Mode Fiber Attenuators
For 300A operation, single-mod e fib er loss must b e b etween 10d B and  17dB (at 
1300 to 1310 nm). Sinc e saturation may oc c ur if d istanc es are short, attenuators 
may b e req uired  if the total loss on the fib er link is less than 10d B. Perform an 
OTDR or Op tic al Power Meter test to d etermine sp ec ific  req uirements. Typ ic ally, 
fib er distanc es of 9 miles (14 km) or less req uire an in-line attenuator. 
Using  Fig ure A -1
, find  the line that most c losely matc hes the c ustomer’s fib er 
p lant, or overlay your own load line. Using  the measured  loss of 0.33d B/km as an 
examp le, install a 10d B attenuator if the d istanc e is ab out 9 miles (14 km) or less. 
Use a 5d B attenuator if the d istanc e is from 9 to 18 miles (14.4 to 30 km).

.
2. Connec t the p atc hc ord  to the required  attenuator. The attenuator must b e 
installed  in series with the strand of fib er c onnec ting  to the TX c onnec tor.
3. Rep eat for the TX c onnec tor at the op p osite end  of the fib er link (remote 
EPN). A d ifferent value attenuator may b e req uired , d epend ing  on the 
amount of fib er loss b ac k to the loc al system.
NOTE:
If the fib er link is d up lic ated , route the fib er via a sep arate 
g eog raphic al path, if p ossib le. This way, if the stand ard fib er link is 
damaged, the duplicated fiber remains in service. Figure Notes
