Methode Electronics Inc. has developed the new MDB-9 Gigabit Optical Extender, a high-performance copper-to-optical converter for bidirectional communication over single- or multimode fiber. The previous limit of 25 m in copper connections can be extended to 500 m on 50-µm multimode fiber at 1.0625 GBd. The system's low-laser-output power allows the extender to be used in arbitrated loop applications for constant communication transmission and data receiving. The device's standard DB-9 electrical interface facilitates connection to the back of a workstation, and the SC duplex optical interface allows interconnection to fiber cabling. Fully compliant with Fiber Channel X3T11, physical layer standard PH-2 and Media Interface Adapter specifications, the MDB-9 also meets Class 1 safety limits.
