standards compliance and safety the 266-mbps and 1063-mbps glm cards support the american national standards institutes (ansis) fibre channel standard. fibre channel is a flexible, cost-effective solution that provides a standardized protocol for system-level interconnect. it features capabilities for high-speed, medium- distance (up to 10 km) data links between processors and peripherals. the glms are ul- and csa-approved. in addition, they are approved internationally as class 1 laser safe products and feature optical emission levels below the recom- mended levels for eye safety. for more information, visit our web site at www.chips.ibm.com. the ibm 266-mbps and 1063-mbps gigabit link modules (glms) are laser- based data communications links that enable computer manufacturers to inte- grate low-cost, high-speed fiber-optic communications into computers and peripherals.these powerful devices are well-suited for a wide range of intercon- nects in fibre channel applications. because of their high speed and low latency, these cards are also useful for connecting two or more computers in shared computing and parallel process- ing environments. advanced features ? short-wavelength (sw) or long-wave- length (lw) lasers ? high-reliability optics ? bit error rates less than 10 -12 ? low-loss sc-type push-pull connectors ? parallel data i/o interface ? double-sided surface-mount technology product description the 266-mbps and 1063-mbps glm cards support continuous, full-duplex communication.the glm converts encoded data that has been serialized into pulses of laser light for transmission into the optical fiber. a glm at a second optical link, running at the same speed as the sending glm, receives these pulses, along with the requisite synchro- nous clocking signals. another device then deserializes the signals into decoded data. the 266-mbps and 1063-mbps glms are available with optional open fiber control (ofc) circuitry that disables the lasers if there is a break in the optical link. ibm microelectronics 266-mbps glm and 1063-mbps glm gigabit link modules for optical data transfer highlights glm electrical specifications for system interconnect. system a t x glm r x system b transmit data transmit byte clock enable wrap lock to reference enable comma detect receive data receive byte clock (2) comma detect fault receive data receive byte clock (2) comma detect fault transmit data transmit byte clock enable wrap lock to reference enable comma detect r x glm t x duplex optical fiber cable
