DATA SHEET| JUNE 14, 2006 EC-48 2.5 Gbit/s External Cavity Directly Modulated Lasers 200 km, 400 km, and 650 km reach The EC48 series directly modulated external cavity laser is a cost effective solution for 2.5 Gbits/s digital transmission up to 650 km in SMF-28 fiber. The laser is fabricated in a 14-pin hermetically sealed butterfly package that incorporates a bias tee circuit, an integrated Applications Metro and Long Haul DWDM, 100 GHz spaced networks SONET/SDH OC-48/STM16 ring and meshed applications Drop-side of DWDM long-haul transport equipment thermoelectric cooler (TEC), a thermistor, and a back facet monitor photodiode. The EC48 provides substantially lower dispersion penalty and lower chirp than a directly modulated DFB. The wavelength stability is assured by design, eliminating the need for wavelength lockers and complex feedback control circuits.

Handling and Mounting 1. The Laser should be mounted on a heat sink at least 13 x 35 mm in size with surface finish better than 1 m and flatness better than 25m. It is recommended that the laser be mechanically mounted to the heat sink using M2-3 mm (#2-56) screws. Apply torque 0.1-0.11 m*N (0.8-1 lb*in). It is also recommended to use thermally conductive grease between the laser package and heat sink. 2. The fiber pigtail must not be subject to a bend radius below 35mm.The fiber is unable to withstand temperatures in excess of 120 C without degradation.
