E1 Pdh Multiplexers

These E1 PDH Multiplexers are cost-effective devices for extending multiple voice and data circuits over fiber optic links. China Tekwaya s PDH optical line multiplexer can transmit -4E1/8E1/16E1 channels and one FULL rate 100Mbps Ethernet signal(optional), respectively, up to 120 kilometers (75 miles) over optical fiber. Typical users of optical line multiplexing equipment include transportation and utility companies, Internet service providers (ISPs) and carriers extending data and voice from SDH/SONET networks or backhauling cellular traffic.As an option, the PDH multiplexer can be equipped with tekwayundant links and power supplies, ensuring transmission reliability and fail-safe operations.

Featuresi
Reliable E1 transmission
Tekwaya s PDH multiplexers transmit each of the E1 signals independently, so that the clock of each E1 channel is independent of the clock of any other E1 channel. The E1 interface can be 75IC unbalanced or 120IC balanced.
Various optical interfaces are available:
- 850 nm for use with multimode fiber
- 1310 nm for use with multimode fiber
- 1310 nm or 1550 nm laser for extended range over single mode fiber
- single fiber option
Also available are the card versions with central SNMP management, for mounting in the rack. These provide a compact, cost effective central solution working opposite standalone optical line multiplexers.
