25G Cooled DML TOSA

25G cooled DML TOSAs consist of a DFB laser, a monitor photodiode and a micro-TEC support, and support LWDM, MWDM and DWDM at O-band wavelength region. It guarantees highly stable operation under I-temp operation. It is designed for use in small form-factor pluggable (SFP) transceivers and other types of optical modules for high-speed telecommunication and 5G x-haul applications.

Features

  • Cooled DML integrated into TO-56
  • Data rate up to 25Gb/s
  • 25Ω single-ended data input
  • Operating temperature: -40℃ ~ 85℃
  • LC receptacle interface
  • Power consumption < 0.5W
  • SFP28 form-factor compatible

Wavelength Plan

The wavelength band between 1298-1321nm in DWDM application is deferred to avoid four-wave mixing crosstalk. It can be used for guard-band for bi-directional transmission.
