Cisco ONS 15454 SDH Product Overview

Card Slots and Types

STM-16 LH AS 1550 Card

The OC48 IR/STM16 LH AS 1550 card provides one long-range port per card,

compliant with ITU-T G.707 and G.957. The port operates at 2.488 GBits/s

(Gbps) over a single-mode fiber span. The card supports concatenated or

non-concatenated VC4 payloads.

STM-16 EH 100 GHz DWDM Card

Eighteen distinct OC48 ELR/STM16 EH 100 GHz dense wavelength division

multiplexing (DWDM) cards provide the ONS 15454 SDH DWDM channel plan.

Although the ONS 15454 SDH uses 200-GHz spacing, these cards also work in

100-GHz-capable systems. Each STM-16 DWDM card provides one port per

card, compliant with ITU-T G.692, G.707, G.957, and G.958. The port operates

at 2.488 GBits/s (Gbps) over a single-mode fiber span. The card supports

concatenated or non-concatenated VC4 payloads.

Nine of the cards operate in the blue band with spacing of 100 GHz on the ITU

grid. The other nine cards operate in the red band with spacing of 100 GHz on the

ITU grid.

STM-64 LH 1550 Card

The OC192 LR/STM64 LH 1550 card provides one long-range port per card,

compliant with ITU-T G.707 and G.957. The port operates at 9.95 GBits/s (Gbps)

over unamplified distances of up to 80 km with different types of fiber such as

C-SMF or dispersion-compensated fiber limited by loss and/or dispersion. The

card supports concatenated or non-concatenated VC4 payloads.

Ethernet Cards

The Ethernet cards eliminate the need for external Ethernet aggregation

equipment and provide efficient transport and co-existence of traditional TDM

trafficwith packet-switched datatraffic.Multiple E-seriesEthernet cards installed

in an ONS 15454 SDH can act as a single switch (EtherSwitch) supporting a

variety of SDH port configurations.
