(a 62.5/125 m m multimode fiber can be substituted with shorter maximum link distances.) encoded (8b/10b) [4], [5], gigabit serial differential pecl signals traverse a pth connector interfacing the 1x9-1063/1250-sw to the host card. the incom- ing serial data modulates the laser and is sent out over the outgoing fiber of a duplex cable. incoming modulated light is detected by a photore- ceiver mounted in the sc receptacle. the optical signal is converted to an electrical signal, amplified and delivered to the host card. this module is designed to work with industry standard 10b seri- alizer/deserializer modules. the 1x9-1063/1250-sw is a class 1 laser safe product. the optical power levels under normal operation are at eye safe levels, and optical fiber can be connected and disconnected without shut- ting off the laser transmitter. .
ibm42b10snnaa10 IBM42B12SNNAA10 gigabit ethernet/fibre channel 1x9 transceiver page 2 of 14 5/25/01 laser safety compliance requirements the 1x9-1063/1250-sw is designed and certified as a class 1 laser product. if the power supply voltage exceeds 6.0 volts, the transceiver may no longer remain a class 1 product. the system using the 1x9-1063/1250-sw must provide power supply over-voltage protection that guarantees the supply does not exceed 6.0 volts under all conditions. caution: operating the power supply above 6.0v or otherwise operating the 1x9-1063/1250-sw in a manner inconsistent with its design and function may result in hazardous radiation exposure, and may be considered an act of modifying or new man- ufacturing of a laser product under us regulations contained in 21cfr1010 and 21cfr1040, or cen- elec regulations contained in en 60825. the per- son(s) performing such an act is required by law to recertify and reidentify the product in accordance with the provisions of 21cfr1010 and 21cfr1040 for distribution within the united states, and in accordance with provisions of cenelec en 60825 (or successive regulations) for distribution within the cenelec countries or countries using the iec 825 standard. esd notice it is advised that normal static precautions be taken in the handling and assembly of the 1x9-1063/1250- sw to prevent damage and/or degradation which may be introduced by electrostatic discharge. package outline pin assignments pin name type pin # rx ground ground 1 rx_dat + signal out 2 rx_dat - signal out 3 rx_sd status out 4 rx

input, an ac coupled differential data stream from the host, enters the ac modulation section of the laser driver circuitry where it modulates the output optical intensity of a semiconductor laser. the dc drive main- tains the laser at the correct preset power level. in addition, safety circuits in the dc drive will shut off the laser if a fault is detected. the transceiver provides the ac coupling for the +tx/-tx lines. no ac coupling capacitors are required on the host card for proper operation. receive section the incoming modulated optical signal is converted to an electrical signal by the photoreceiver. this electrical signal is then amplified and converted to a differential serial output data stream and delivered to the host. a transition detector detects sufficient ac level of modulated light entering the photoreceiver. this signal is pro- vided to the host as a signal detect status line. the transceiver provides the ac coupling for the +rx/-rx lines. no ac coupling capacitors are required on the host card for proper operation. block diagram post-amp signal detect and +tx_dat +rx_dat fiber input photoreceiver output fiber -rx_dat rx_sd -tx_dat laser ac modulation

is presented to the 1x9-1063/1250-sw for transmission onto an optical fiber by modulating the optical output intensity of the laser. the transceiver provides the ac coupling for the +tx/-tx lines. output signal de?nitions levels for the signals described in this section are listed in receive signal interface on page 6 and control electrical interface on page 7. rx_dat the incoming optical signal is converted and repowered as a differential pecl serial data stream. the receive signal interface table on page 6 gives the voltage levels and timing characteristics for the rx_dat signals. the transceiver provides the ac coupling for the +rx/-rx lines. rx_sd the receive signal detect line is high (a logical one) when the incoming modulated light intensity is suf?cient for reliable operation. this is the state for normal operation. the line is low (a logical zero) when the incoming modulated light intensity is below that required to guarantee the correct operation of the link. normally, this condition only occurs when either the link is unplugged or the companion transceiver is turned off. this signal is normally used by the system for diagnostic purposes. this signal has a push-pull output driver . receive signal detection rx_sd t_sd_off <100 m s t_sd_on <100 m s signal removed optical signal ibm42b10snnaa10 IBM42B12SNNAA10 gigabit ethernet/fibre channel 1x9 transceiver

nite extinction ratio at the minimum specified oma. 2. optical transition time is the time interval required for the rising or falling edge of an optical pulse to transition between the 20% and 80% amplitudes relative to the logical 1 and 0 levels. this is measured through a 4th order bessel -thompson ?lter with 0.75 * data rate 3-db bandwidth and corrected to the full bandwidth value. 3. extinction ratio is the ratio of the average optical power (in db) in a logical level one to the average optical power in a logical level zero measured under fully modulated conditions with a pattern of ?ve 1s followed by ?ve 0s, in the presence of worst case re?ec - tions. 4. optical modulation amplitude (oma) is de?ned as the difference in optical power between a logical level one and a logical lev el zero. the oma is de?ned in terms of average optical power (p avg in m w) and extinction ratio (er) as given by oma=2p avg ((er- 1)/(er+1)). in this expression, the extinction ratio, de?ned as the ratio of the average optical power (in m w) in a logic level one to the average optical power in a logic level zero measured under fully modulated conditions in the presence of worst case re?ections, must be the absolute (unitless linear) ratio and not expressed in db. at 1.0625 gb/s, the speci?ed oma is equivalent to an average power of -9 dbm at an extinction ratio of 9 db. 5. rin12 is the laser noise, integrated over a speci?ed bandwidth, measured relative to average optical power with 12db return loss. see ref[1], annex a. 6. eye opening is the portion of the bit time where the bit error rate (ber) 10 -12 . 7. deterministic jitter is de?ned in ref [1][2]. 8. coupled power ratio is the ratio of the average power coupled into a multimode ?ber to the average power coupled into a singl e mode ?ber. this measurement is de?ned in eia/tia-526-14a. ibm42b10snnaa10 IBM42B12SNNAA10 gigabit ethernet/fibre channel 1x9 transceiver 5/25/01 page 9 of 14 optical cable and connector speci?cations symbol parameter min typical max. unit notes 50/125 m m cable specifications (multimode 850 nm, 400 mhz-km) l length -
