Description of the problem
New OSN products are more and more, compared to SDH products, customers are relatively unfamiliar, customers often consult the range of receive sensitivity and overload point of a certain optical board in SDH products, for the commonly used veneer we can say the range, but we may not be able to memorize the prepared values, we need to go to the 8.0 CD-ROM or suppport website for querying, the customer perception is poor and both sides need to consume time.
Processing
To summarize the Bom code, board type, corresponding standard wavelength (nm), transmission distance (km), typical light-emitting power (dBm), typical receiving sensitivity (dBm), and maximum dispersion permitted by the channel (ps/nm) of the commonly used optical boards in SDH products, refer to the Appendix-List of the Commonly Used Optical Boards in OSN Products for their optical power. Huawei OSN3500 devices SSN1BA2 & SSN1BPA provide two sets of LC fiber interfaces. Table 1: SSN1BA2 single board optical interface description
