OC48 ELR/STM16 EH 100 GHz Cards

4.27 OC48 ELR/STM16 EH 100 GHz Cards

Thirty-seven distinct OC48 ITU 100GHz dense wavelength division multiplexing (DWDM) cards

provide the ONS 15454 DWDM channel plan. Each OC-48 DWDM card has one SONET OC-48/SDH

STM-16 port that complies with Telcordia, GR-253 SONET, and the International Telecommunication

Union’s ITU-T G.692, and ITU-T G.958.

The port operates at 2.49 Gbps over a single-mode fiber span. The card carries VT, concatenated, and

non-concatenated payloads at STS-1, STS-3c, STS-6c, STS-12c, or STS-48c signal levels. Figure 4-29

shows the OC48 ELR/STM16 EH 100 GHz faceplate and a block diagram of the card.

Figure 4-29 OC48 ELR/STM16 EH 100 GHz faceplate and block diagram

Nineteen of the cards operate in the blue band with spacing of 100 GHz on the ITU grid standard G.692

and Telcordia GR-2918-CORE, issue 2 (1528.77 nm, 1530.33 nm, 1531.12 nm, 1531.90 nm, 1532.68

nm, 1533.47 nm, 1534.25 nm, 1535.04 nm, 1535.82 nm, 1536.61 nm, 1538.19 nm, 1538.98 nm, 1539.77

nm, 1540.56 nm, 1541.35 nm, 1542.14 nm, 1542.94 nm, 1543.73 nm, 1544.53 nm).

The other eighteen cards operate in the red band with spacing of 100 GHz on the ITU grid (1546.12 nm,

1546.92 nm, 1547.72 nm, 1548.51 nm,1549.32 nm, 1550.12 nm, 1550.92 nm, 1551.72 nm, 1552.52 nm,

1554.13 nm, 1554.94 nm, 1555.75 nm, 1556.55 nm, 1557.36 nm, 1558.17 nm, 1558.98 nm, 1559.79 nm,

1560.61 nm). These cards are also designed to interoperate with the Cisco ONS 15216 DWDM solution.
