10T3062 / 10T3063 – 10Gbps 1310nm Uncooled
Electroabsorption Modulated Laser (EML) TOSA
Special Temperature Range (-5°C to 85°C)
with SC / LC Receptacle – 10GbE
Product Overview
The 10T3062 / 10T3063 TOSA features CyOptics’ (formerly
Apogee Photonics’) 1310nm next generation uncooled EMLs
for outstanding DC and RF performance over a wide
temperature range in a low-cost TO-41-based TOSA. The
device features high-stability optics with isolation, thermistor-
based temperature monitoring, modulator-based power
monitoring.
A key feature that distinguishes CyOptics’ 1310 EML TOSA
from 1310 nm directly modulated laser based TOSAs is that
the EML-TOSA provides high eye-margins with good
extinction ratios over the entire temperature operating range.
This is achieved by optimization of the modulator for high
bandwidth and high extinction with low modulator drive
voltages, while the single-frequency laser is optimized for
output power, temperature stability, reliability and spectral
quality.
Fig. 1 – SC TOSA (10T3062) is shown.
