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

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.

absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in

excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for

extended periods can adversely affect device reliability.

Reliability/Quality

Designed to meet qualification requirements of Telcordia (Bellcore) GR468-Core and operating reliability <500

FITs (Assumes laser die submount held at <40oC by internal thermoelectric cooler, mean forward current of

50mA, and end of life limits based on 10mA increase in Ith and 25% change in laser efficiency).

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 μm

and flatness better than 25μm. 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 ºC without degradation. Avoid high temperature contact during soldering
