Intended for synchronous-optical-network and cable-TV transmissions at rates as high as 10 Gbps, a 1550-nm distributed-feedback laser diode provides a power output of 15 mW. The FU-68PDF-2M9 has an internally matched 25 Ohm package that includes a polarization-maintaining fiber pigtail for compatibility with external modulators. The butterfly package also has a thermal electric cooler. The FU-68PDF-2M9 costs $6000 (100). Mitsubishi Electronics America Inc, Sunnyvale, CA. (408) 730-5900.
Four distributed-feedback laser diodes with optical isolators target hybrid-fiber/coaxial broadband networks. Two pigtail modules, the 0L3492L and 0L5492L, have respective wavelengths of 1310 and 1510 nm and support transmission rates of up to 1.5 Gbps. Typical minimum threshold current is 20 mA, and fiber output power is 1 mW. Operating at the same wavelengths are two thermal-electric-cooled butterfly pigtail modules for trunking applications. The 0L3104L and 0L5104L are both rated for OC-48 (2.5-Gbps) transmission at 2 mW of output power. Pigtail modules cost $2000; butterfly modules cost $4000 (small quantities).

To save board space and reduce insertion costs, the 564-0X20-XXX indicator supplies three vertically mounted 3-mm LEDs in a DIN 41494-compatible housing. The devices come in a 2-mA version, and you can specify assemblies with an integral resistor and bicolor LEDs. Red, green, and yellow LEDs operate at 635-, 565-, and 583-nm wavelengths, respectively. Light output ranges from 1.6 mcd for the 2-mA version to 10 mcd for the 10-mA version. The devices cost $1.22 (1000). Dialight Corp, Manasquan, NJ. (908) 223-9400.
Operating at a line voltage of 120V, the 120PCL-X LED lamp lasts 100,000 hours compared to 1000 hours for 120PC incandescents. The lamp operates at 5.5-mA current compared to 25 mA for incandescent bulbs. It drops into standard 120PC sockets and comes in red, orange, amber, yellow, green, blue, and red/green (for white lenses). The LED in all colors except blue costs $5.19 (1000); the blue LED costs $10.47 (1000). Data Display Products, El Segundo, CA. (310) 640-0442.
Designed for the microLED series of surface-mount LEDs, the Optopipe light pipe mounts over an RJ45 jack. The four-element array, designated the 515-1022, routes light from the LED to its intended viewing location, typically at a right angle from the circuit board. The light pipe is useful in designs requiring a horizontal or vertical array of LED indicators. The Optopipe has 0.550-in. (horizontal) spacing between pipes and a 0.2×0.12-in. illuminating surface. Total height is 0.81 in. It costs <$1 (1000). Dialight Corp, Manasquan, NJ. (908) 223-8700.
Hermetically sealed surface-mount IR components in the SMD/SME series satisfy the sensing requirements of optical encoders for motion control and computer-peripheral applications. The series comprises the SME2470 IR-emitting diode and either the SMD2440 silicon-phototransistor detector or the SMD2420 silicon-photodiode detector in a two-layer alumina ceramic package with a glass lens. Nominal dimensions are 0.150 in. long×0.10 in. wide×0.083 in. high. Prices range from $1.22 to $1.50 (5000). Honeywell Micro Switch Division, Freeport, IL. (800) 367-6786.
