Optical Protection Card(OLP) are used for DCI Box
The main function of the OLP optical protection board is to assist the wavelength division system to complete optical layer protection solutions such as optical line 1+1 protection and optical wavelength 1+1 protection. It can monitor the signal status of the main and standby routes in real time. Once the optical signal is interrupted or the performance deteriorates, it can automatically make safe switching on the main and standby routes to ensure the rapid recovery of the system optical signal. OLP technology is to complete the route switching operation in the optical layer. The optical layer protection has the incomparable advantages of the upper layer service protection, and is the best solution to provide users with non-blocking communication.
Datasheet Optical Protection Card (OLP) Function Support optical signal 1+1 protection, double send and receive, single end switching Integration degree One or two groups of optical protection modules (optional based on application scenarios) Operating wavelength range 1528nm ~ 1568nm Insertion loss The originating end ≤4 dB and the receiving end ≤1.5 dB Switching time <5 ms (pure optical switching time) Input optical power -25dBm ~ +21 dBm Optical power detection accuracy ±0.5 dBm (@>-25 dBm or above) Polarization dependent loss ≤0.1dB Isolation >50dB Return loss >45dB Switching frequency ＞(10)^7 Switching condition Relative power difference and absolute power Switching mode Supports locking, forced switching, manual switching, and automatic switching Reliability Power failure/power-on latch, hot swap, and main control failure do not affect the protection switchover
Application : For Optical line 1+1 Protection (OLP) For Optical multiplexing segment 1+1 Protection (OMSP) For Optical Channel 1+1 Protection (OCHP) Suitable for DCI Box
