Huawei OSN500 TNM1CQ1 processing board supports 4 ports channelized STM-1
The functional version of CQ1 boards is TNM1.
The feature code of a board refers to the number next to the board name in the bar code and indicates the type of optical port. CQ1 boards have feature codes.
Feature codes of the CQ1
|Type of Optical Port
|S-1.1, eSFP optical module
|L-1.1, eSFP optical module
|L-1.2, eSFP optical module
|S-1.1, single-fiber bidirectional optical module (For optical ports 1 and 2, the transmit wavelength is 1310 nm and the receive wavelength is 1550 nm; for optical ports 3 and 4, the transmit wavelength is 1550 nm and the receive wavelength is 1310 nm.)
TNM1CQ1 Valid Slots
A CQ1 board can be inserted in slot 3 or slot 4, with slot 4 preferred. Its logical slot on the network management system (NMS) is the same as its physical slot.
