copyright 2010 fujitsu component limited 1 description newly developed optical transceiver, fujitsu component ?s o-microgigacn? series supports electric to optical interface conversion and provides 5 gbps x 4 channel, bidirectional data transfer. the electr ical interface is fujitsu component?s industry standard high-speed differential copper connector, microgigacn? that has been selected by infiniband? and 10g ethernet. the o-microgigacn? makes it possible to extend transmission length up to 300m (2.5gbps) over fiber optic cable from industr y standard 4 lane copper cable with media detection circuit (connector detect and power supply circuit) on the customer?s board/host side. the module provides flexibilit y, allowing the user to select interface options with the one low cost copper i/o connector on the board. the module provides a low cost solution for data center requirements. figure 1: over view o-microgigacn ? 4-channel optical transceiver part number of module: fpd-10*r008-0e features z converts 4x microgigacn ? to 4x optical interface z optical interface 12-channel mpo connector z up to 100m links with standard 50/125u m mmf ribbon cable at 3.125gbps and 5 gbps, y and up to 300m at 2.5 gbps z reliable, low cost 850nm vcsel technology z 0 to + 50 degree c operating temperature range z low power: 0.9 watts typical with 3.3v power supply supplied through connector z hot pluggable electrical interface z iec class 1m laser eye safety compliant z rohs compliant o-microgigacn? datasheet 2010.04.01 rev. 1.0

copyright 2010 fujitsu component limited 6 supply power to the o-microgigacn? the microgigacn? usually does not provide power for the module. the draft proposal of fc-pi-2 allows the re-assignment of some ground pins as power pins, as shown in the following table 8. this re-assignment does not affect the function or performance of standard cable connection for infiniband? and 10g ethernet applications, as the powe r is added only when the system is sure the attached module is ?active?. the re -assigned pins are all ac ground to minimize the effect on high- speed signal integrity. table 8: pin assignment in fc-pi-2 connector pin number alternate signal definitions g1 signal ground g2 odis g3 signal ground g4 signal ground g5 signal ground g6 fault- g7 type_sense g8 vcc g9 signal ground s1 rx0+ s2 rx0- s3 rx1+ s4 rx1- s5 rx2+ s6 rx2- s7 rx3+ s8 rx3- s9 tx3- s10 tx3+ s11 tx2- s12 tx2+ s13 tx1- s14 tx1+ s15 tx0- s16 tx0+ housing chassis ground o-microgigacn? datasheet 2010.04.01 rev. 1.0
