1 Lightning Series Mil-Dtl Fiber Optic Transceiver, RS-485 DC to 1.0MHz pplications, Multimode, 850nM Quad Port, Jam-Nut Receptacle FTURS Suitable for RS-485 datalinks at datarates from DC to 1.0MHz Optical fiber link distances up to 2.0 Kilometers Operating temperature range from -40 C to +85 C Shock, vibration and immersion resistant per Mil-Std-810 Olive drab cadmium over electroless nickel shielding meets stringent MI / RFI performance requirements Mil-T compliant optical fiber interface Connector insert configuration conforms to Mil-Std-1560 PPLICTIONS Lightning series bulkhead mounted optical transceivers enable high speed communications links over long distances in harsh environments. The Mil-Dtl-38999, Series III aluminum shell provides a sealed optical interface that is water-tight to Mil-Std-810 / IP67 / NM-4x when mated. The multimode optical fiber interface supports applications where copper cable link distance, bandwidth limitations, weight or bulk make the use of twisted pair, coax, twinax or quadrax copper conductors unacceptable. Four TX & Four RX Channels Operating from DC to 1.0MHz DSCRIPTION Lightning series optical fiber transceivers consist of optoelectronic transmitter and receiver functions integrated into a bulkhead mounted Mil-Dtl series III receptacle connector. The optical transmitters operate at 850nM. The transmitter input lines are driven with differential RS-485 signals applied to the transmitter lines. The optical receivers consist of PIN and preamplifier assemblies and limiting post-amplifiers. Outputs from the receivers consist of differential RS-485 data signals on the receiver lines. The electrical interface to the Lightning series optical transceivers is a Mil-Std Micro D-Subminiature connector enabling connection to a customer supplied cable assembly. Lightning series optical fiber transceivers are vibration isolated, environmentally hardened components ready for use in harsh environment applications. Sealed against liquid and solid contaminants Shock and vibration resistant ORDRING INFORMTION pplication Product Number RS-485, DC to 1.0MHz P38J-8S18-HW-M 1

2 BSOLUT MXIMUM RTINGS bsolute maximum limits mean that no catastrophic damage will occur if the product is subjected to these ratings for short periods, provided each limiting parameter is in isolation and all other parameters have values within the performance specifi cation. It should not be assumed that limiting values of more than one parameter can be applied to the product at the same time.
