A polarization-maintaining fiber output option is available for the IQS-, IQ-, and FLS-2600B tunable laser sources for the C- and L-bands. The fiber at the laser's connector provides an extinction ratio of >18 dB and a known polarization state at the source output. This makes it possible to characterize the response of a polarization-maintaining passive component or a component sensitive to the input state of polarization.

The QT2020 is a monolithic transceiver designed for use in 10 Gigabit Ethernet local-area and metropolitan-area network applications. Combined on the chip are the receiver and transmitter functions, clock generation, multiple loopback features, and the generation and checking of pseudorandom binary-sequence test patterns on both the attachment-unit interface standard and 10-Gbit/s sides. The device meets IEEE 802.3ae and XENPAK specifications.

The OTS9200 jitter analysis module uses Digital Phase Analysis technology to verify compliance with standards from 155 Mbit/s to 10 Gbit/s. The module, which uses a high-bandwidth silicon germanium device used in the company's oscilloscopes, time stamps every edge of a SONET/SDH data stream. It performs jitter generation and jitter tolerance tests and does not require range switching or PLL settling time.

The Digital BeamProfiler near-infrared imaging system includes an InGaAs array sensor of 30 x 30-μm pixels. The camera is a sensor head measuring 5.3 x 6.4 x 9.5 cm. The system includes profiling software and a 12-bit digital framegrabber card, and allows 2-D profiles for wavelengths from 900 to 1700 nm. The system can operate as a stand-alone tool or can be used with ActiveX or GPIB automation equipment for integration into automated manufacturing processes.

Avalanche photodiodes (APDs) for transponder/transceiver applications are based on InGaAs and are available in 2.5- and 10-Gbit/s versions. They can be used to build CWDM metro-access equipment. The APDs are available on a submount, or in a TO-46 can with an integrated transimpedance amplifier. They can increase the link budget of a fiber link by 6 to 8 dB.
Sensors-Demeter Components Group, Princeton, NJ

The 520D35 series laser light sources offer dual wavelengths of 1310 and 1550 nm with output of -10 dBm or higher for testing single-mode fiber or components. Output can be cw or modulated at speeds of 270, 1000, or 2000 Hz. LEDs indicate laser operation and modulation. The devices come with interchangeable FC, ST, or SC adapters of a fixed FC optical port.

The BraggStar Industrial LN is a UV light source with a temporal coherence length of approximately 5 mm for the interferometric writing of fiber Bragg gratings. The beam has spatial coherence on approximately 1.5 mm horizontally and 0.7 mm vertically at 248 nm, with maximum stabilized energy of 2 mJ and repetition rate to 1 kHz.
TuiLaser, Munich, Germany

ZMUX passively thermally compensated multiplexers and demultiplexers have wavelength drift of 0.43 pm/°C over the -5°C to 70°C operating range, providing a stable and consistent passband. The devices are available in 16-, 20-, 32-, and 40-channel versions with 100-GHz spacing.
Zolo Technologies, Louisville, CO

The EPM980 laser pump module for EDFA's emits 50 to 120 mW at 980 nm. It can operate without cooling over a range of 0°C to 70°C. The module includes the diode and a lens in a TO-can mount, packaged for replacement of butterfly devices.
Blue Sky Research, Milpitas, CA

The ONS 15808 is a DWDM transmission platform that handles 2.5- and 10-Gbit/s systems and supports 40 Gbit/s for future growth, for use in long-haul and extended long-haul networks. It offers 80 channels with 50 GHz spacing, out-of-band forward error correction, optical channel protection, and automated power provisioning. The platform supports ANSI and ETSI standards.
Cisco Systems, San Jose, CA

The SS series of nonmechanical, nonorganic fiberoptic switches has switching times <50 ms, optical loss of 0.7 dB, latching operation, intrinsic high stability, and direct low-voltage TTL drive. The solid-state, all-crystal switches are designed for continuous high-speed operation.
Agiltron, Woburn, MA

An amplified spontaneous-emission light source designed to cover the entire S-band from 1480 to 1510 nm uses a thulium-doped optical fiber amplifier. The source is designed to be used when measuring and evaluating optical products for the S-band.
NTT Electronics Corp., Tokyo, Japan

Aluminum coating enhances the tensile strength of optical fibers and allows operation at high temperatures, making them suitable for applications such as Raman amplification using power >1 W. The coating can be applied to the company's specialty fibers, including rare-earth-doped fibers. Typical coating thickness is approximately 22 μm for cladding diameters of 125 μm.
