Description

The Optimux-1551 E1 fiber mux and Optimux-1553 E1 fiber mux are unique STM-1 / OC-3 multiplexers that offer high port density at an affordable cost. The units map multiple E1 or T1 tributary channels into a single channelized STM-1/OC-3 uplink, enabling the extension of the local loop up to 80 km (50 miles), while creating a transmission layer fully compatible with regional and national SDH/SONET networks. The 2U high Optimux-1551 E1 fiber mux provides connectivity for 21 E1, 42 E1or 63 E1 channels or 28 T1, 56 T1 or 84 T1 lines, while the 1U high Optimux-1553 E1 fiber mux provides connectivity for three E3 or three T3 lines. The products comply with all SDH/SONET standards, and interface with existing SDH/SONET backbones through a single or redundant STM-1/OC-3 or STS-3 interface.

Further Product Information The Optimux-1551 E1 fiber mux and Optimux-1553 E1 fiber mux deliver traditional PDH services over existing SDH / SONET networks. They combine the high capacity associated with SDH / SONET add-drop multiplexers (ADMs) with the simplicity and low cost of a terminal multiplexer, significantly reducing operating and capital expenses (Opex and Capex).


High capacity in a compact, plug-and-play unitOptimux-155x E1 fiber mux products are designed to dramatically reduce capital and operating expenditures by combining the high capacity of SDH / SONET ADMs with the simplicity, low cost and small size of a terminal multiplexer. The 2U high Optimux-1551 E1 fiber mux provides connectivity for up to 63 E1 or 84 T1 lines, and the 1U high Optimux-1553 E1 fiber mux provides connectivity for three E3 or three T3 lines. The products comply with all SDH / SONET standards, and interface with existing SDH / SONET backbones through a single or redundant STM-1, OC-3 or STS-3 interface.



The Optimux-1551 E1 fiber mux can be ordered with 21 x E1/ 28 x T1 lines, 42 x E1/ 56 x T1 lines as well as 63 x E1/84 x T1 lines.


Carrier-class design Designed for the rigorous requirements of carriers and service providers, Optimux-1551 E1 fiber mux and Optimux-1553 E1 fiber mux devices offer a high level of reliability and manageability. Hardware redundancy is designed into the system without the need for custom Y-cables or external devices. This 1+1 redundancy is provided for all user interfaces through an optional second, hot-swappable multiplexer card. 1+1 redundancy is also available for the STM-1/OC-3 main link (uni-directional APS/MSP) and power supply modules. This reliable platform maximizes uptime for mission-critical applications. A fully equipped Optimux-1551 E1 fiber mux fits in a single 2U 19" shelf while the Optimux-1553 E1 fiber mux occupies a 1U shelf.

Higher revenues at lower cost The Optimux-155x E1 fiber mux devices allow service providers to extend their network towards remote customers, thereby enlarging their customer reach and increasing revenues, without the expenses associated with deploying high-end ADMs, which add unnecessary cost and complexity in �point to network� connections. Compared to the alternative of deploying PDH multiplexers at customer sites, the Optimux-155x E1 fiber mux devices interface directly with the existing SDH / SONET TDM infrastructures and consolidate traffic at the edge of the network. This enables service providers to save the cost of fiber deployment and of multiple ports on the ADM.

Plug-and-play operation Easy to install, maintain and operate, Optimux-155x E1 fiber mux requires no training or expertise. As completely plug-and-play units, the products allow carriers to extend the benefits of SDH / SONET networks toward the customer premises or central office in a quick and inexpensive manner.
