The module is comprised of a directly-modulated DFB laser chip and a co-packaged proprietary optical spectrum reshaper (OSR) passive optical element. The OSR component also provides a frequency locking function and allows operation on the ITU-T channels within 2.5GHz with coverage across both Cband and L-band for DWDM versions. Also included in the standard butterfly footprint are 2 photo-detectors for power control and wavelength locking, together with 2 TECs for temperature stabilization. Key specifications for the optical and electrical characteristics, physical requirements, environmental conditions and reliability/quality requirements are detailed in this document. Note: Long version of this document with more detailed optical and electrical parameter specification is available upon request.

Internal Optical Layout Isolator PD2 L2 L1 Fibre stub OSR DFB Isolator TEC Window PD1 Beamsplitter Figure 1 Figure 1. CML internal layout The DM200-01 modules uses a 10Gb/s directly modulated DFB chip co-packaged with an optical spectral re-shaper (OSR) element as shown in Figure 1. An optical isolator is included between the DFB and the OSR while a beam-splitter component and 2 photodetectors are configured to allow frequency locking. Lens#1(L1) is used to collimate the DFB laser output and pass the beam through the splitter and OSR, prior to coupling into single-mode fiber using Lens#2 (L2). A second isolator is included in the fiber pigtail to minimize the effect of external back-reflections on module performance. II. Control Method The schematic in Figure 2 shows the key components and control loops that are used to operate the module. The output power of the DFB is monitored by photodetector PD1. Photodetector PD2 monitors the back-reflection from the OSR. The photocurrent ratio from the two detectors is used to lock the relative spectral locations of the laser and the OSR via temperature control of the DFB using TEC#1. A second TEC (TEC#2) controls the temperature of the OSR and locates the operating point of the OSR on the ITU grid for DWDM applications.
