3.24 OC48 ELR/STM16 EH 100 GHz Cards
Eighteen distinct STM-16 ITU 100 GHz dense wavelength division multiplexing (DWDM) cards
comprise the ONS 15454 SDH DWDM channel plan. This plan contains every second in a series of 100
GHz spacing wavelengths. Though the ONS 15454 SDH only uses 200 GHz spacing, the cards work in
100 GHz spacing nodes, as well. Each OC48 ELR/STM16 EH 100 GHz card provides one ITU-T G.692,
ITU-T G.707, ITU-T G.957, ITU-T G.958-compliant, SDH STM-16 port. The interface operates at
2.488 GBits/s (Gbps) over a single-mode fiber span. Each card supports concatenated or
non-concatenated payloads at STM-1, STM-4, or STM-16 signal levels on a per VC-4 basis. Figure 3-39
shows the OC48 ELR/STM16 EH 100 GHz faceplate and Figure 3-40 shows a block diagram of the card.
Warning
Class 1 laser product.
