Optical Service Channel Cards

 

 

 

 

 

OSCM

 

15454-OSCM=

The OSCM card has one set of optical ports and one Ethernet port

 

 

 

located on the faceplate. The card operates in Slots 8 and 10.

 

 

 

An OSC is a bidirectional channel connecting all the nodes in a ring.

 

 

 

The channel transports OSC overhead that is used to manage

 

 

 

ONS 15454 DWDM networks. The OSC uses the 1510 nm

 

 

 

wavelength and does not affect client traffic. The primary purpose of

 

 

 

this channel is to carry clock synchronization and orderwire channel

 

 

 

communications for the DWDM network. It also provides transparent

 

 

 

links between each node in the network. The OSC is an OC-3

 

 

 

formatted signal.

 

 

 

The OSCM is used in amplified nodes that include the OPT-BST

 

 

 

booster amplifier. The OPT-BST includes the required OSC

 

 

 

wavelength combiner and separator component. The OSCM cannot be

 

 

 

used in nodes where you use OC-N cards, electrical cards, or

 

 

 

cross-connect cards. The OSCM uses Slots 8 and 10 when the

 

 

 

ONS 15454 is configured in a DWDM network.

 

 

 

 

OSC-CSM

 

15454-OSC-CSM=

The OSC-CSM card has three sets of optical ports and one Ethernet

 

 

 

port located on the faceplate. The card operates in Slots 1 to 6 and 12

 

 

 

to 17.

 

 

 

The OSC-CSM is identical to the OSCM, but also contains a combiner

 

 

 

and separator module in addition to the OSC module.

 

 

 

The OSC-CSM is used in unamplified nodes. This means that the

 

 

 

booster amplifier with the OSC wavelength combiner and separator is

 

 

 

not required for OSC-CSM operation. The OSC-CSM can be installed

 

 

 

in Slots 1 to 6 and 12 to 17 when the ONS 15454 is configured in a

 

 

 

DWDM network.

 

 

 

Optical Amplifiers

 

 

 

 

 

OPT-PRE

 

15454-OPT-PRE=

The OPT-PRE card is designed to support 64 channels at 50 GHz

 

 

 

channel spacing. The OPT-PRE is a C-band DWDM, two-stage EDFA

 

 

 

with mid-amplifier loss (MAL) for allocation to a DCU. To control the

 

 

 

gain tilt, the OPT-PRE is equipped with a built-in variable optical

 

 

 

attenuator (VOA). The VOA can also be used to pad the DCU to a

 

 

 

reference value. You can install the OPT-PRE in Slots 1 to 6 and 12 to

 

 

 

17 when the ONS 15454 is configured in a DWDM network.

 

 

 

 

OPT-BST

 

15454-OPT-BST=

The OPT-BST card is designed to support up to 64 channels at 50 GHz

 

 

 

channel spacing. The OPT-BST is a C-band DWDM EDFA with OSC

 

 

 

add-and-drop capability. When an ONS 15454 DWDM has an

 

 

 

OPT-BST installed, it is only necessary to have the OSCM to process

 

 

 

the OSC. The card has a maximum output power of 17 dBm. To

 

 

 

control the gain tilt, the OPT-BST is equipped with a built-in VOA.

 

 

 

You can install the OPT-BST in Slots 1 to 6 and 12 to 17 when the

 

 

 

ONS 15454 is configured in a DWDM network.

15454 specifications

Cisco Systems' 15454 is a leading optical networking platform designed to address a range of connectivity needs for service providers, enterprises, and data centers. As part of the Cisco ONS (Optical Networking System) portfolio, the 15454 provides advanced capabilities that cater to the evolving demands of high-performance network requirements.

At its core, the Cisco 15454 is built for scalability and versatility. It supports a variety of transmission methods, including SONET (Synchronous Optical Networking), SDH (Synchronous Digital Hierarchy), and WDM (Wavelength Division Multiplexing). This flexibility makes the platform ideal for deploying both legacy services and next-generation applications.

One of the standout features of the 15454 is its ability to support high-capacity wavelengths, allowing for greater bandwidth utilization across fiber networks. With advanced Dense Wavelength Division Multiplexing (DWDM) technology, the platform ensures efficient use of the available fiber and extends the distance over which data can be transmitted. This results in reduced operational costs while maximizing throughput.

The Cisco 15454 also comes equipped with an array of interfaces supported by its modular design. The platform can accommodate Ethernet, SONET/SDH, and IP services, which means it can seamlessly handle a wide range of protocols. The modular architecture allows network operators to tailor the system to their specific requirements, offering a variety of line cards and interfaces to choose from.

Another critical characteristic of the 15454 is its built-in protection mechanisms. The system offers diverse and automatic protection schemes such as optical Layer 1 protection, ensuring high availability and network resilience. This capability is essential for mission-critical applications where uptime is paramount.

Moreover, the platform is complemented by Cisco's sophisticated management solutions, which streamline the operational management of the network. With tools that provide in-depth monitoring and troubleshooting capabilities, network administrators can maintain optimal performance and quickly respond to any issues that may arise.

In summary, the Cisco Systems 15454 is a robust and adaptable optical networking solution. Its main features, including advanced DWDM capabilities, modular architecture, protocol versatility, and enhanced protection mechanisms, make it a preferred choice for organizations looking to scale their network infrastructure while ensuring high service reliability and performance. Whether for expanding bandwidth or modernizing legacy networks, the Cisco 15454 stands out as a powerful tool in the ever-evolving landscape of telecommunications.
