The EOLS-1330-DT-10-DN series single mode transmitter is small form factor pluggable module for dual transmitter data communications. It is with the SFP 20-pin connector to allow hot plug capability. This module is designed for single mode fiber and operates at a nominal wavelength of 1310nm. The transmitters use 1310nm multiple quantum well laser and is a class 1 laser compliant according to International Safety Standard IEC-60825. The EOLS-1330-DT-10-DN series provides extensive operational status monitoring through an I2C interface. Output optical power and bias current are monitored. Other operating conditions such as power supply and operating temperature are also monitored.
