OTR 1840
3G SDI Fiber Transceiver (CWDM)
The OTR 1840 is a CWDM Fiber Optic to SDI transmitter and receiver combined in a compact self contained package. It is a convenient and cost effective solution to combat the restrictions involved with the distribution of uncompressed broadcast quality video signals over long distances.
Each OTR 1840 CWDM transceiver has an independent transmitter and receiver channel, which provides an effective solution for any SDI signal up to 1080p60 (3Gbit/s) while preserving full uncompressed quality. Select from 18 transmitter wavelengths for full CWDM compatibility (ITU-T G.694.2)
The OTR 1840 will auto-detect and re-clock any 270Mbit / 1.5Gbit / 3Gbit SDI source prior to conversion. The module is fully compatible with 3Gbit Level A and Level B formats.
Note: The module DOES NOT INCLUDE the fiber SFP, When ordering please specify an SFP option in the wavelength required
