OPTICAL RECEIVER The DSC-R404 optical receiver from Discovery Semiconductors can be used for 40-Gbit/s transmissions, with optical preamplification, SONET/SDH, and RF over fiber from the L- to Q/V-bands. It offers a conversion gain from 35 V/W to 70 V/W and has bandwidth from 100 kHz to >35 GHz. It is hermetically sealed in a small-footprint package and built following GR-468 standards.

INTERLEAVERA 50-GHz interleaver doubles the capacity of OC-192 systems by interleaving wavelengths, allowing up to 160 channels, for a system capacity of 1.6 Tbit/s. It operates without active temperature control and is compact. New Focus, San Jose, CA www.newfocus.comFIBER COUPLING LENS
A SMF-28 collimating lens provides focusing for applications at OC-192 and above. It positions a fiber 250 µm from the input surface of the lens, which is wedged to eliminate back reflection. It has a 1.8-mm diameter and focal length of 2.9 mm with a tolerance of ±0.1%. It is AR-coated for C-band operation and has an insertion loss <0.5 dB. CommOptics, Irvine, CA, www.commoptics.com
S-BAND TRANSPONDER
The MTP102-OS31-C transponder operates at 10 Gbit/s and incorporates a 1310-nm short-wavelength electroabsorption modulated laser and a photoreceiver with an integrated limiting amplifier. It has sensitivity of >-19 dBm at a bit-error rate of 1E-10, with rise and fall times of 30 ps. It has a 200-pin FCI connector. Multiplex, South Plainfield, NJ, www.multiplexinc.com
OPTICAL PROFILER
The NSOM/AFM-100 confocal micro-optical profiler uses a cantilevered optical-fiber probe to scan over the microlensed or other optical fiber element, measuring the topography of the lens while light is collected at each point down to 50-nm resolution. It can monitor the distribution of light at various optical planes in micron or submicron steps from above the fiber tip through the focal point.

EDFA
The IOE 1100 C-band erbium-doped fiber amplifier is designed for long-haul and ultralong-haul applications. It covers 1529.83 to 1561.92 nm, has total input power of -5 dBm, output power of 22 dBm, gain ripple of 1 dB over a single temperature and 1.7 dB over the whole temperature range, noise figure of 6.5 dB at 27-dB gain, and PMD of 0.5 ps.
