OC48 ELR/STM16 EH 100 GHz Cards

Figure 3-39 OC48 ELR/STM16 EH 100 GHz faceplate

Nine of the cards operate in the Blue Band with a spacing of 2 * 100 GHz in the ITU grid (1530.33 nm,

1531.90 nm, 1533.47 nm, 1535.04 nm, 1536.61 nm, 1538.19 nm, 1539.77 nm, 1541.35 nm, 1542.94 nm).

The other nine cards operate in the Red Band with a spacing of 2 * 100 GHz in the ITU grid (1547.72

nm, 1549.32 nm, 1550.92 nm, 1552.52 nm, 1554.13 nm, 1555.75 nm, 1557.36 nm, 1558.98 nm, 1560.61

nm).

You can install the OC48 ELR/STM16 EH 100 GHz cards in any high-speed slot. You can provision this

card as part of a MS-SPRing or SNCP. In an ADM/TM configuration, you can provision the card as either

an access tributary or a transport span interface.

Note Slots 5, 6, 12, and 13 are high speed slots.

Each OC48 ELR/STM16 EH 100 GHz card uses extended long reach optics operating individually

within the ITU 100 GHz grid. The OC48 ELR/STM16 EH 100 GHz cards are intended to be used in

applications with long unregenerated spans of up to 200 km (with mid-span amplification). These

transmission distances are achieved through the use of inexpensive optical amplifiers (flat gain

amplifiers) such as erbium doped fiber amplifiers (EDFAs). Using co-located amplification, distances

up to 200 km can be achieved for a single channel (160 km for 8 channels).
