STM-1/4/16 SDH Multiplexer

In my older post I have covered the basic STM and STM-1. STM1 is a synchronous digital hierarchy (SDH) is standardized multiplexing protocols that transfer multiple digital bit streams over optical fiber using lasers or light emitting diodes (LEDs).

The STM-1 / STM-4 can be managed through an integrated NMS to manage all the equipment, providing customers through end-to-end provisioning from a single platform for multiple service types such as E1/DS1s, E3/DS3s, E4/STM-1e and STM-1o. In some equipment, vendors provide 10/100Mbps Ethernet services and single 10/100Base-T Ethernet port. Some STM-1 OEMs offers both electrical STM-1 (1+1) and optical STM-1 (1+1) interfaces. It can be customized for the traffic demands, in the access network, typical of residential or business needs at organizations. The System comes with latest optical networking software with the intelligence of SONET/SDH to deliver a flexible, cost-effective network solution.

Many OEMS have their STM multiplexer product in market such as Gigabit, GL Communication, VCL100MC-1 STM-1, Data Connect Enterprise, Patton Electronics, E-Link,  AN-STM-1-ETH (AD-Net) etc.

If we talk about the device or multiplexer itself, let’s see an example with basic features of one STM Device such as VCL 100MC of VALIANT COMMUNICATIONS. For more information and technical specification, you can refer to the data sheet at respective website of Valiant Communication provided below.

Valiant VCL100 is an ultra-compact, carrier class and cost-effective bandwidth provisioning STM1/4/16 SDH Multiplexer equipment designed to manage and deliver services from the optical core to the access.

The STM-1/4/16 SDH Multiplexer equipment supports end-to-end provisioning and management of services across all segments of the optical network. It combines innovative optical networking software with the resilience of SDH to deliver a flexible solution to today's service providers.

The VCL100 can be configured as a Terminal Multiplexer (TMUX), Add-Drop Multiplexer (ADM), Regenerator, In-Line Amplifier or as a stand-alone Cross-Connect. A variety of service interfaces such as E1/DS1, E3/DS3, STM-1e/o and 10/100/1000 Mbps Ethernet tributary interfaces and trunk interfaces at STM-1/4/16 rates are supported. The product features non-blocking cross connect at VC-3, VC-4 and VC-12 granularity and supports drop and continue functionality.

Some glance of Features

• They are Compact in size.
• Integrated multi-service Delivery 
• Redundant cards with hot insertion capability 
• Multi-level protection schemes MSP, or SNCP
• Advanced networking software with support for open standards such as GMPLS and OSPF.

And if we considering the operating environment, all the devices work under -5 degree to 50 degree Celsius temperature and 10% to 90% of humidity range. 

So for more information or technical datasheet please refer to OEM websites.
