New Features for Release 10.0
This section highlights new features for Release 10.0. For detailed documentation of each of these features, see the user documentation.
These hardware units have been introduced in Release 10.0:
EDRA-1-xx and EDRA-2-xx Cards
(ONS 15454 M6 only)
The double-slot EDRA-1-xx and EDRA-2-xx cards are erbium-doped Raman amplifiers (EDRAs) that support Raman amplification on long unregenerated spans. The EDRA cards support an ultra-low noise figure that is critical for long-distance, high-bit-rate transmission. Each EDRA card can manage up to 96 channels, 50-GHz-spaced from 196.1 GHz (1528.77nm) to 191.35 GHz (1566.72 nm). The EDRA cards are plug-in modules that provide the reach and optical performance required to meet the most demanding distance requirements of service provider and enterprise networks.
The EDRA cards have four versions:
- EDRA1-26 includes an erbium doped pre-amplifier, EDFA1, with a nominal gain of 14 dB. It supports a maximum span of 26 dB on standard single-mode fiber.
- EDRA1-35 includes an erbium doped pre-amplifier, EDFA1, with a nominal gain of 21 dB. It supports a maximum span of 35 dB on standard single-mode fiber.
- EDRA2-26 includes an erbium doped pre-amplifier, EDFA1, and an erbium doped booster amplifier, EDFA2, where EDFA1 has a nominal gain of 14 dB. It supports a maximum span of 26 dB on standard single-mode fiber.
- EDRA2-35 includes an erbium doped pre-amplifier, EDFA1, and an erbium doped booster amplifier, EDFA2, where EDFA1 has a nominal gain of 21 dB. It supports a maximum span of 35 dB on standard single-mode fiber.
For more information about the EDRA cards, see the Provisioning Optical Amplifier Cards chapter in the Cisco ONS 15454 DWDM Line Card Configuration Guide, Release 10.x.x.
(ONS 15454 M6 only)
The double-slot cross connect 16-port Flex Spectrum ROADM line card (16-WXC-FS) can be used at the core of the network. The card is used to build ROADM nodes with 96 channels spaced at 50-GHz, flex spectrum channels, or a combination of the two. The card provides the flex spectrum capability, which allows the user the flexibility to allocate channel bandwidth and increase the network scalability. The channel bandwidth is not fixed, but can be defined arbitrarily, with a given granularity and within a given range. Attenuation and power values are defined for each sub-range. The frequency ranges from 191'350 Ghz (1566 .72 nm) to 196'100 Ghz (1528 .77 nm). The 16-WXC-FS card can be used in point-to-point, ring, multi-ring, or mesh topologies. The 16-WXC-FS card supports up to 16 directions for each ROADM node.
For more information about the 16-WXC-FS card, see the Provisioning Reconfigurable Optical Add/Drop Cards chapter in the Cisco ONS 15454 DWDM Line Card Configuration Guide, Release 10.x.x.
Passive Optical Modules
(ONS 15454 M2 and ONS 15454 M6)
A new generation of passive optical modules can be used to accommodate ROADM nodes built with the 16-WXC-FS and EDRA cards. Three types of modules are available: patch panel modules, add/drop modules, and adapter modules. All the modules fit into four slots of a 1-rack-unit (1RU) mechanical frame chassis (MF-1RU). Their passive nature helps ensure extremely high availability in a small, low-power footprint. ECU3 is required for these passive modules.
The passive modules are:
- 5-Degree Patch Panel Module (MF-DEG-5)
- 4-Degree Upgrade Patch Panel Module (MF-UPG-4)
- 16-channel Colorless Omnidirectional Add/Drop (MF-16AD-CFS)
- 4-channel Colorless Omnidirectional Add/Drop (MF-4X4-COFS)
- MPO-8xLC Adapter (MF-MPO-8LC)
For more information about the ROADM passive modules, see the Installing the Cisco ONS 15454 M2 and ONS 15454 M6 Passive Optical Modules document.
100G-CK-C and 100ME-CKC Cards
(ONS 15454 M2 and ONS 15454 M6)
The 100G-CK-C and 100ME-CKC cards are tuneable over the entire C-band. The 100G-CK-C card works similar to the 100G-LC-C card. The 100G-CK-C card has the new CPAK client interface replacing the CXP client interface of the 100G-LC-C card.
The 100G-CK-C and 100ME-CKC cards support the CPAK-100G-SR10 client interface with 100GE/OTU4 and 40GE/OTU3 payloads. Both the cards support the CPAK-100G-LR4 client interface with 100GE/OTU4 payloads. The CPAK client interface enables different payload combinations such that the 100G-CK-C card can be used instead of the 100G-LC-C and CFP-LC cards.
The 100ME-CKC is a metro edge version of the 100G-CK-C card. The 100ME-CKC card has chromatic dispersion of +/-5000 ps/nm and does not support 20% FEC.
For more information about the 100G-CK-C and 100ME-CKC cards, see the Provisioning Transponder and Muxponder Cards chapter in the Cisco ONS 15454 DWDM Line Card Configuration Guide, Release 10.x.x.

New Software Features
These software features have been introduced in Release 10.0:
Restoration Based on LSP Priority
The control plane supports the Label Switch Path (LSP) priority signaling on the UNI interface. The LSP priority can be set using CTC or TL1. The LSP priority is used to resolve a conflict on any network resource when two or more LSPs are set at the same time, and requires the same resources. The LSP priority is critical during circuit creation and restoration.
The LSP priority is used to decide the GMPLS restoration in a multiple channel setup, and optimizes the restoration time for an LSP with a higher priority. The restoration is dynamic, managed by the head node and simplifies network operations. In a circuit failure, the dynamic optical restoration enables the automatic re-routing of the optical circuit over a new route. The GMPLS intelligence embedded in the circuit enables the DWDM layer to dynamically validate the feasibility of the new route. This ensures a successful network connectivity and eliminates the dependancy on additional design tools.
LSP Setup with Regenerators
The regenerators in the network minimize the signal loss, and helps to establish an uninterrupted connection between the source and destination. The control plane uses LSP setup and the regenerators in the circuit to create segments during failure in the optical path. A regenerator connects each segment in the network. The wavelength changes at each regenerator, if the wavelength continuity between the two end points is not available. A regenerator failure triggers the restoration process.
Control Plane in Coherent Networks
The optical impairments in full coherent networks follow the LOGO model (Local Optimization Global Optimization) that is applicable to 100G full coherent networks. The optical impairment is calculated node by node, and can be identified by adding the local contribution penalty of the nodes or spans in the path. The crosstalk between optical channels can be pre-defined in network design phase and considered as a constant by the control plane. The need to signal the values of all the optical parameters to the egress node (to calculate the channel feasibility and the residual margins of existing channels) is eliminated. Each add or drop domain is associated a value that represents the penalty calculated due to signal loss. This operation is done during network setup or network upgrade.
CTC notifies the user when duplicate patchcords are created, either manually or by using the NE Update configuration file. The user can choose to retain the existing patchcord or overwrite the existing patchcord with the new patchcord.
