 |
CATS Converged Access & Transport System is a next generation optical system platform for WDM, TDM and Ethernet applications
With this system, service providers can offer various bandwidth configurations using Ethernet and/or E1/T1 protocols, while aggregating all services on to the metro network. The centrally managed platform accepts plug-in cards which also fit into a stand-alone small chassis as CPE (customer premises equipment). |
| |
CATS 3 platforms:
| 1U rack CATS 1000 for 2 x 3U line cards
| 3U rack CATS 3000 for 10 x 3U line cards
| 6U rack CATS 6000 for 24 line cards |
| |
| Why CATS? |
| CATS provides a variety of interfaces and services, from PDH to Ethernet, as well as fiber channel. Using WDM technology, CATS collects these different services and connect them to the metro networks. |
|
|
CATS is intended for edge and access applications. In the access networks, customers may have a variety of interfaces such as PDH, IP, fiber channel, or SDH/Sonet. The large variety of services make it difficult for service providers to aggregate and to control, because the equipment is often interface or sevice dependant.

| WDM or TDM? |
TDM equipment aggregates multiple interfaces using time domain multiplexing. A TDM equipment can take in different protocols or interfaces and then mix them into an upstream. Typically TDM equipment uses un-colored fiber optic transceivers. New generation of TDM equipment like our MTX2550 (page 30) offers several types of interfaces including Ethernet, PDH and Gigabit Ethernet. Typical trunk bandwidth is 2.5G or below, which allows to connect access customers to the remote metro SDH/Sonet networks.
When bandwith requirement is limited, and there is no SAN services such as fiber channel, TDM may be a lower cost solution than WDM. |
 |
| TDM Application Example: Collecting various services in the access network, and connecting them to the metro network using single wavelength. The metro network is usually SDH/Sonet based. And trunk speed is 2.5 G or below. |

| WDM or Ethernet Aggregation? |
The new generation of Ethernet equipment, such as our 10 G Ethernet Transport Switch MTS1080, can aggregate Ethernet services while transporting traffics up to 80 km without regeneration.
MTS1080 is best used for an IP based access network, which does not involve PDH or other datacom services. The metro network can be either IP based or SDH/Sonet based but a protocol conversion (to Ethernet) is needed at the metro edge. The maximum trunk capacity is 10 G. |
 |
| Ethernet Aggregation Example: Collecting IP services in the access network, and connecting them to the metro network using 10 GbE. |
| |
| CWDM or DWDM? |
When trunk bandwidth needs to be more than 10G, and/or there is storage network interface involved, WDM becomes necessary.
CWDM is best used for short distance access aggregation service. Typical transmission distance ranges from 2 km to 40 km.
CATS is optimized for CWDM transport, due to its low cost and compactness. Each RC-U 3U rack can host up to 16 CWDM channels.
DWDM is less common in the edge/access networks. However, fiber optic components and equipment costs are dropping dramatically in the recent years, making DWDM accessible for short distance transport.
Typically, when trunk bandwidth needs to be larger than 80 Gbps, DWDM shall be considered.
CATS 6U RC-HD/63 rack, with 24 slots available for line cards, offers unprecedented compactness for DWDM applications.
