TMB1LDC is a 2-channel 100Gbit/s to 1-channel OTUC2/OTU4 service convergence wavelength conversion board applied to Huawei 1800 I&II Compact, 1800 II TP, 1800 II Enhanced, OSN 1800V. The LDC board is a wavelength conversion board and applies to coherent systems, the board maps optical signals received on the client side into one OTUC2 or OTU4 signal, and performs mutual conversion between the OTUC2/OTU4 signal and the optical signal carried over an ITU-T-compliant WDM wavelength.
|There are ports on the front panel of the board.|
|Specifications (in OTU mode)|
|Basic functions||Working modes of the board and ports|
Supports two working modes: 200G and 100G. In the 100G working mode, the TX2/RX2 is unavailable. The mapping paths of the board are as follows:
1. 200G line:
a. 100GE <—> ODU4(GMP) <—> ODUC2 <—> OTUC2
b. 100GE <—> ODU4(GFP-F) <—> ODUC2 <—> OTUC2
c. OTU4 <—> ODU4 <—> ODUC2 <—> OTUC2
2. 100G line:
a. 100GE <—> ODU4(GMP) <—> OTU4
b. 100GE <—>ODU4(GFP-F) <—> OTU4
c. OTU4 <—> ODU4 <—> OTU4
