A370-Type Analog Uncooled Laser Module Description The A370-Type Uncooled Laser Module consists of a laser diode coupled to a single-mode fiber pigtail. The device is available in a standard, 8-pin configuration (see Figure 1 and/or Table 1) and is ideal for CATV applications. The module includes a multiquantum-well Fabry-Perot (MQW F-P) laser and an InGaAs PIN photodiode backfacet monitor in an epoxy-free, hermetically sealed package. The device characteristics listed in this document are met at 1.0 mW output power. Higher- or lower-power operation is possible. Under conditions of a fixed photodiode current, the change in optical output is typically ±0.5 dB over an operating temperature range of –40 °C to +85 °C. This device incorporates the new Laser 2000 manufacturing process from the Optoelectronics unit of Lucent Technologies Microelectronics Group. Laser 2000 is a low-cost platform that targets high-volume manufacturing and tight product distributions on all optical subassemblies. This platform incorporates an advanced optical design that is produced on the Optoelectronic unit’s highly automated production lines. The Laser 2000 platform is qualified for the central office and uncontrolled environments, and can be used for applications requiring high performance and low cost.

Lucent Technologies Inc. 3 A370-Type Analog Uncooled Laser Module Data Sheet March 2001 Electro/Optical Characteristics (continued) Analog Operation The A370 Series Laser Module has the capability of being used in a wide variety of analog operations. These may include several channels of pure video signals, or a mix of video signals with digital data channels riding on analog carriers. It is difficult to prepare a single battery of testing conditions that will satisfy all applications. The following table contains a set of testing conditions that Lucent believes will give a broad indication of the performance of the A370 Series Laser Module. Please contact your local Field Application Engineer if different testing conditions and parametric limits are required. The distortion characteristics are measured using a two-tone test. The frequencies are 13 MHz and 19 MHz. The second-order distortion components are measured at f1 + f2 = 32 MHz and f1 – f2 = 6 MHz. All third-order distortion components are measured in the frequency range of 5 MHz—200 MHz, and they meet the required level. All measurements are made with SC-SPC connectors on the laser module pigtails. Table 3.
