Chapter 4 Optical Cards
4.1.2 Card Compatibility
Note The Cisco OC3 IR/STM1 SH 1310-8, OC12 IR/STM4 SH 1310, and OC48 IR/STM16 SH AS 1310
interface optics, all working on 1310 nm, are optimized for the most widely used SMF-28 fiber, available
from many suppliers.
Corning MetroCor fiber is optimized for optical interfaces that transmit at 1550 nm or in the C and L
DWDM windows, and targets interfaces with higher dispersion tolerances than those found in
OC3 IR/STM1 SH 1310-8, OC12 IR/STM4 SH 1310, and OC48 IR/STM16 SH AS1310 interface optics.
If you are using Corning MetroCor fiber, OC3 IR/STM1 SH 1310-8, OC12 IR/STM4 SH 1310, and
OC48 IR/STM16 SH AS 1310 interface optics become dispersion limited before they become
attenuation limited. In this case, consider using OC12 LR/STM4 LH 1550 and OC48 LR/STM16 LH
1550 AS cards instead of OC12 IR/STM4 SH and OC48 IR/STM16 SH cards.
With all fiber types, network planners/engineers should review the relative fiber type and optics
specifications to determine attenuation, dispersion, and other characteristics to ensure appropriate
deployment.
4.1.2 Card Compatibility
Table 4-2 lists the CTC software compatibility for each optical card. See Table 2-5 on page 2-4 for a list
of cross-connect cards that are compatible with each optical card.
OC192 LR/STM64
LH 1550
The OC192 LR/STM64 LH 1550 card provides one
long-range STM-64 port at 1550 nm and operates in
Slots 5, 6, 12, or 13 with the XC10G card.
See the “4.13 OC192
LR/STM64 LH 1550 Card”
section on page 4-35.
OC192 LR/STM64
LH ITU 15xx.xx
The OC192 LR/STM64 LH ITU 15xx.xx card provides
one extended long-range STM-64 port and operates in
Slots 5, 6, 12, or 13 with the XC10G card. This card is
available in multiple wavelengths in the 1550-nm
range of the ITU grid for 100-GHz-spaced DWDM.
See the “4.14 OC192
LR/STM64 LH ITU 15xx.xx
Card” section on page 4-39.
