Multiplex to Unveil Transponder

SOUTH PLAINFIELD, N.J. -- At the National Fiber Optic Engineers Conference (NFOEC, Baltimore, Maryland, July 8-12) Multiplex, Inc. will demonstrate a new variation of its 10 gigabits-per-second (10b/s) MTR10G transponder. The demonstration will feature a transponder that integrates Multiplex’s MTX310EW 10Gb/s 1310nm SEML (Short-wavelength Electro-absorption Modulated Laser) and MTRX192L (the first photoreceiver with an integrated limiting amplifier). Multiplex has designated this transponder as the MTP102-OS3I-C.Multiplex’s first-generation transponder was based on its MTX-TEML (tunable 1550nm EML transmitter). The 1310nm fixed-wavelength version is designed to better meet the current demands of network system architects. In June 2001, Multiplex introduced the MTX310EW as the world’s first SEML based on 1310nm technology (the MTX310EW is designed to maximize the near-zero dispersion properties of the “S” band). Compared with directly-modulated lasers, the MTX310EW offers much better signal quality (eye pattern) and is much easier to use. Due to the integrated limiting amplifier of the MTRX192L, sensitivity of the MTP102-OS3I-C is extremely high (better than –19dBm at a bit-error-rate of 1E-10). During live loopback testing, eye patterns of the 1310nm variant have been consistently generated with rise-and-fall times of 30 pico-seconds.Shortly after its introduction in April 2001, Multiplex’s transponder was accepted into the Multi Source Agreement (MSA) for OC192 transponders. The MTP102-OS3I-C has the distinction of being the first to meet the MSA’s small-form-factor intermediate-reach (IR2) specifications for Metro and long-haul applications. Like Multiplex’s first transponder, the newest version features a 200-pin FCI connector and a package that measures only 2.03” x 3.01” x 0.56”. 300-pin packaging is also available, as are 1550nm variants. Multiplex will be shipping samples of its fixed-wavelength and tunable transponders in the second half of this year, with volume production expected three to six months after that. “During the developmental stages of the 1310 SEML, we knew this technology was ideal for transponder applications,” said Dr. Won T. Tsang, Multiplex’s President and CEO. “The ability to produce 1310 and 1550 nm versions with fixed and tunable wavelengths, and in the smallest packaging, has helped to position Multiplex’s transponders at the technological forefront of the industry.” Multiplex Inc.For more information on NFOEC, please visit the Light Reading NFOEC Site.
