15 12. the extinction ratio i s a meas ure of the modulation depth of the optical s ignal. the data 0 output optical power is compared to the data 1 peak output optical power and expre ssed as a percentage. with the trans mitter driven by a halt line state (12.5 mhz s quare-wave) s ignal, the average optical power i s meas ured. the data 1 peak power is then calculated by adding 3 db to the meas ured average optical power. the data 0 output optical power i s found by meas uring the optical power when the trans mitter is driven by a logic 0 input. the extinc tion ratio i s the ratio of the optical power at the 0 level compared to the optical power at the 1 level expressed as a percentage or in decibels . 13. the tran s mitter provides compliance with the need for transmit_dis able commands from the fddi smt layer by providing an output optical power level of < - 45 dbm average in re spons e to a logic 0 input. this s pecifcation applies to either 62.5/125 m or 50/125 m fber cables . 14. thi s parameter complies with the fddi pmd requirements for the trade-of s between center wavelength, s pectral width, and rise/fall times s hown in figure 9. 15. thi s parameter complies with the optical puls e envelope from the fddi pmd s hown in figure 10. the optical rise and fall times are meas ured from 10% to 90% when the tran s mitter is driven by the fddi halt line state (12.5 mhz s quare-wave) input s ignal. 16. duty cycle di s tortion contributed by the trans mitter is meas ured at a 50% threshold us ing an idle line state, 125 mbd (62.5 mhz s quare-wave), input s ignal. see application information - trans ceiver jitter performance section of this data s heet for further de - tails . 1. data dependent jitter contributed by the tran s mitter is s pecifed with the fddi tes t pattern des cribed in fddi pmd annex a.5. see applica- tion information - tran s ceiver jitter performance section of this data s heet for further details . 18. random jitter contributed by the tran s mitter is s pecifed with an idle line state, 125 mbd (62.5 mhz s quare-wave), input s ignal. see applica - tion information - tran s ceiver jitter performance section of this data s heet for further details . 19. thi s s pecifcation is intended to indicate the performance of the receiver s ection of the trans ceiver when input optical power s ignal char - acteri stics are pres ent per the following defnitions . the input optical power dynamic range from the minimum level (with a window time- width) to the maximum level i s the range over which the receiver is guaranteed to provide output data with a bit error ratio (ber) better than or equal to 2.5 x 10 -10 . ? at the beginning of life (bol) ? over the s pecifed operating temperature and voltage ranges ? input s ymbol pattern is the fddi tes t pattern defned in fddi pmd annex a.5 with 4b/5b nrzi encoded data that contains a duty cycle bas e-line wander efect of 50 khz. thi s s equence causes a near worst cas e condition for inter-s ymbol interference. ? receiver data window time-width i s 2.13 ns or greater and centered at mid-s ymbol. this worst cas e window time-width is the minimum allowed eye-opening pre s ented to the fddi phy pm._data indication input (phy input) per the example in fddi pmd annex e. this minimum win - dow time-width of 2.13 n s is bas ed upon the worst cas e fddi pmd active input interface optical condition s for peak-to-peak dcd (1.0 n s ), ddj (1.2 ns) and rj (0.6 ns ) pres ented to the receiver. to te s t a receiver with the worst cas e fddi pmd active input jitter condition requires exacting control over dcd, ddj and rj jitter compo - nent s that is difcult to implement with production tes t equipment. the receiver can be equivalently tes ted to the worst cas e fddi pmd input jitter condition s and meet the minimum output data window time-width of 2.13 ns . thi s is accomplis hed by us ing a nearly ideal input optical s ignal (no dcd, ins ignifcant ddj and rj) and meas uring for a wider window time-width of 4.6 ns . thi s is poss ible due to the cumula- tive efect of jitter component s through their s uperpos ition (dcd and ddj are directly additive and rj components are rms additive). specif - cally, when a nearly ideal input optical te st s ignal is us ed and the maximum receiver peak-to-peak jitter contributions of dcd (0.4 ns), ddj (1.0 ns), and rj (2.14 ns ) exis t, the minimum window time-width becomes 8.0 ns -0.4 ns - 1.0 ns - 2.14 ns = 4.46 ns , or con s ervatively 4.6 ns . thi s wider window time-width of 4.6 ns guarantees the fddi pmd annex e minimum window time-width of 2.13 ns under worst case input jitter condition s to the avago technologies receiver. ? tran s mitter operating with an idle line state pattern, 125 mbd (62.5 mhz s quare-wave), input s ignal to s imulate any cross -talk pres ent between the transmi t ter and receiver s ections of the trans ceiver. 20. all condition s of note 19 apply except that the meas urement is made at the center of the s ymbol with no window time-width. 21. thi s value is meas ured during the trans ition from low to high levels of input optical power. 22. the signal detect output shall be ass erted within 100 s after a s tep increas e of the input optical power. the s tep will be from a low input optical power, -45 dbm, into the range between greater than p a , and -14 dbm. the ber of the receiver output will be 10 -2 or better during the time, ls_max (15 s ) after signal detect has been ass erted. see fig - ure 12 for more information. 23. thi s value is meas ured during the trans ition from high to low levels of input optical power. the maximum value will occur when the input optical power i s either -45 dbm average or when the input optical power yields a ber of 10 -2 or larger, whichever power i s higher. 24. signal detect output s hall be de-ass erted within 350 s after a s tep decreas e in the input optical power from a level which is the lower of; -31 dbm or p d + 4 db (p d is the power level at which s ignal detect was de-ass erted), to a power level of -45 dbm or less . thi s s tep decrease will have occurred in le ss than 8 ns . the receiver output will have a ber of 10 -2 or better for a period of 12 s or until s ignal detect is de-ass erted. the input data s tream is the quiet line state. als o, s ignal detect will be de-ass erted within a maximum of 350 s after the ber of the receiver output degrade s above 10 -2 for an input optical data s tream that decay s with a negative ramp func tion ins tead of a s tep function. see figure 12 for more information.
