400G Coherent CFP2 Card 4*QSFP28 OTU Service Board For Tunable C-Band 96-Wave Transmission
Olycom 400G Muxponder CFP 2 DWDM Optical Transport Unit
Introduction
- The 400G OTU service board supports four 100G service accesses, adopts advanced technologies such as PDM-QPSK modulation and coherent reception, and overcomes the transmission physical effects of high-speed transmission systems on OSNR requirements, CD tolerance, PMD tolerance, and nonlinearity.
- It can realize 400G business over 1,200 kilometers of non-relay transmission, and the line side interface supports C-band 96-wave (50GHz) tunable.

OTU card management interface
- Online real-time monitoring of the working status of the business disk
- On-line monitoring module link status, port link status
- Real-time monitoring module transmit and receive light power, current working rate
- Support real-time reading of optical module DDM information
- Support reading module wavelength and channel information
OTU Card Setup
1. Device receiving power alarm threshold setting
The receiving power alarm threshold of the optical module can be set through the network management. When the receiving power is lower than the threshold, the device will prompt an alarm and notify the maintenance personnel to pay attention without affecting the business
2. ALS mode setting
The ALS function can be set through the network management system. When the ALS function is enabled, the optical module itself cannot receive light, and the side optical module itself does not emit light.
