DOWNERS GROVE, Ill. With Fibre Channel technology apparently poised for a huge market uptake, Molex Fiber Optics Inc. has joined the fray with a gigabit optical transceiver designed to minimize electromagnetic interference while carrying data over distances up to 10 kilometers. The gigabit in- terface converters (GBICs) come in long- and short-wavelength ver- sions that can also be used in Gigabit Ethernet applications.
The Fibre Channel GBIC transceiver operates at 1.063 Gbits/ second, while a Gigabit Ethernet transceiver moves data at 1.25 Gbits/s. Both hot-pluggable transceiver lines come with either 1,300- or 850-nm wave- lengths and comply with ANSI and IEEE standards, respectively.
The units are all designed to plug into switches that are shipped unpopulated, so system integrators can add GBICs according to their needs. Many current systems have little EMI grounding, so interference problems arise as transceivers are packed in more densely, according to Molex spokesman Bryan Gregory. The Molex transceivers have metal bodies and other design characteristics designed to minimize emissions, he said.
The short- and long-wavelength models operate with a single 5-V power supply that draws 300 mA in steady state. Differential skew is 20 picoseconds, and PECL skew is 205 ps. Average optical output power of the 1,300-nm laser is -3 dB. The module measures 2.7 x 11.09 x 0.472 inch.
Gigabit Ethernet transceivers have similar performance specifications, but provide link distances up to 550 meters using inexpensive multimode fiber cables.
Short-wave units start at $150, with long-wave models priced from $300. Delivery time is typically five weeks.
