SDH Projects

Synchronous Digital Hierarchy (SDH) is a multiplexing protocol for transferring multiple digital bit streams using lasers or light-emitting diodes (LEDs) over the same optical fiber. The method was developed to replace the Plesiochronous Digital Hierarchy (PDH) system for transporting larger amounts of telephone calls and data traffic over the same fiber wire without synchronization problems. SDH are based on circuit mode communication, meaning that each connection achieves a constant bit rate and delay. This system can carry anything from STM-1 to Fast Ethernet in a Network.

Etleimu Communications do SDH Turnkey installations for Telkom that involves site surveys, logistic support, infrastructure support, physical build, fault fining, optic fiber splicing, supply of DC power, system tests and commissioning.

Etleimu does the complete Reticulation of Shelter which includes the following:

 

Installation of base station Installation of TX Cabinets Installation of Batteries Installation of AC and DC power Mechanical and electrical QC Issuing of Certificate of Compliance (COC) Reticulation of existing buildings Build on Site and assembly of flat-pack containers RF Electrical and Mini-links Preparation and alterations on existing buildings Splicing - Fibre Optic Spray painting of containers on site Repairs of Burglar and Vandalised sites Transportation of equipment to site
