63 E1 STM1 SDH multiplexer
The GT-SDH-155A is a compact STM-1 level Synchronous Digital Hierarchy (SDH) multiplexer designed by Guangdong Global Telecommunication Technology Co., Ltd, compliant with ITU-T standards. It supports multiplexing of 63 E1 interfaces into two 155.520Mb/s optical interfaces, functioning as a Terminal Multiplexer (TM) or Add-Drop-Multiplexer (ADM) for point-to-point, ring, or chain networks. The 1U, 19-inch rack-mounted unit features two STM-1 optical ports (SFP modules with LC connectors) and up to 63 E1 tributary interfaces, with optional unbalanced or balanced configurations.
The system includes multiple management and service interfaces: Ethernet (RJ45), RS232 (console and user channel), external synchronisation (ETS/EXM), Engineering Order Wire (EOW), and alarm outputs (UALM/DALM). Timing modes are flexible, supporting STM-1 line timing, tributary timing from any E1 port, external timing inputs (2048Kbit/s or 2048KHz), and an internal ITU-T G.813 oscillator with auto-switching based on SSM or operator settings. Power options include dual 220V AC, -48V DC, or mixed configurations, with consumption under 25W.
This multiplexer is ideal for telecom operators, ISPs, and enterprises requiring high-capacity, reliable data transmission with 1+1 protection and Automatic Protect Switch (APS) under 50ms. It supports Remote Power Down Detection (RPD) and Auto Laser Shutdown (ALS) for safety, along with embedded BERT and loopback testing for troubleshooting. The device operates in temperatures from -10°C to 70°C and is housed in a 484x44x255mm chassis. Buyers should confirm compliance with local telecom regulations and network compatibility before deployment.

Sourcing 63 E1 STM1 SDH multiplexer from Guangdong Global Telecommunication Technology Co., Ltd - China Import Guide
Before purchasing, confirm that the GT-SDH-155A meets your network’s compliance requirements, particularly for ITU-T standards and local telecom regulations. Request a copy of the supplier’s test reports for optical and E1 interface performance, including BER (Bit Error Rate) and jitter measurements. Verify whether the device has undergone interoperability testing with your existing equipment.
Clarify logistics details such as lead time, shipping methods, and incoterms (e.g., FOB Shenzhen or Guangzhou). For air or sea freight, confirm the device’s packing for shock and vibration resistance, as well as any export controls or licences required for telecommunications equipment. Discuss warranty terms, return policies, and technical support availability for post-deployment issues.
Upon delivery, perform a full functional test of the optical and E1 interfaces, including loopback and BERT tests to validate performance. Check the physical condition of the unit for damage and ensure all accessories (e.g., SFP modules, power cables) are included. Request factory calibration certificates and documentation for any custom configurations. Establish a maintenance plan with the supplier for firmware updates and troubleshooting support.
