Optimized for compatibility with global networking equipment, providing reliable Fast Ethernet links across harsh industrial environments.
As Vietnam's financial engine and most populated economic center, Ho Chi Minh City (HCMC) is accelerating its industrial and digital transition under the "Smart City" master plan. Leading tech hubs such as the Saigon Hi-Tech Park (SHTP), Tan Thuan Export Processing Zone, and the newly established Thu Duc City innovation district are driving massive demand for resilient fiber-optic communication systems.
While the market trends heavily toward ultra-high-speed solutions (100G, 400G, and 800G) within hyperscale datacenters, critical legacy architectures—including regional telecommunication loops, utility transmission grids (managed by EVN SPC), railway signaling systems, and factory automation pipelines—continue to depend heavily on the rock-solid stability of 155M and 622M SFP modules.
These optical modules serve as the critical interface link between legacy Ethernet, Fast Ethernet, SDH (STM-1), and SONET systems. Our company provides local system integrators, distributors, and telecom engineering contractors in HCMC with highly customized, industrial-grade transceivers that withstand HCMC's high temperature and humidity fluctuations.
Despite the rise of higher bandwidth standards, low-speed transceivers represent a resilient niche. Below is an overview of why these speeds remain indispensable.
Power substations running IEC 61850 require Fast Ethernet (100Base-FX/LX) fiber loops. At 155Mbps, these links maintain continuous operation immune to electromagnetic interference (EMI).
Optical networks running SDH (STM-1/STM-4) require precise clock recovery. Standard multi-rate SFP modules provide seamless support for both packet Ethernet and legacy TDM traffic.
With lower optical dispersion at 155M/622M speeds, transceivers can achieve massive reach (up to 80km, 120km, or even 160km) over single-mode fiber without complex dispersion compensators.
Leveraging our robust design expertise and automated manufacturing to serve the Ho Chi Minh City telecommunication market.
Founded in 2017, Equip-Link Intelligent Equipment (Shenzhen) Co., Ltd. is a leading manufacturer and supplier of high-performance optical transceivers and fiber optic communication solutions. With over 14 years of industry expertise, our production plant integrates advanced automated manufacturing and testing mechanisms, aligning with the standards of Factory 4.0.
Our facility ensures precise optical alignment, multi-temperature compensation calibrations, and real-time performance logging. By employing our in-house developed firmware programming adapters, we write custom EEPROM compatibility codes for all major hardware vendor architectures including Cisco, Hirschmann, Moxa, Huawei, Allied Telesis, Juniper, and HP.
This strict control of the supply chain enables us to bypass standard lead times. For Vietnamese buyers operating in HCMC, this means access to high-volume manufacturing runs, robust components, and flexible ODM/OEM customization—including custom labels and personalized DDMI threshold settings.
Every single 155M/622M SFP transceiver exported to the Ho Chi Minh City market undergoes multi-tier physical and functional tests to guarantee zero-fail performance.
Our 155M/622M SFP transceivers are integrated into critical communication projects across Southern Vietnam:
The automated signaling system, Passenger Information Display Systems (PIDS), and station intercoms use industrial-grade Moxa and Hirschmann managed Ethernet switches. In these environments, our Moxa-compatible 100M/155M SFPs connect wayside controllers to core networks over fiber, operating reliably in elevated non-air-conditioned track enclosures.
Electricity distribution substations across Thu Duc, Binh Chanh, and Tan Binh utilize IEC 61850 networks. Our single-mode 155M optical transceivers provide links up to 20km and 40km, ensuring real-time monitoring signals reach regional power control centers without electromagnetic degradation.
Industrial zones such as Cat Lai and Hiep Phuoc employ PLC-controlled water management systems. Long-run optical links are established using 100Base-ZX Single Mode SFP 1550nm 80km modules to monitor distant telemetry sensors safely.

B2B optical module sourcing in Vietnam requires navigating the complex regulatory framework managed by the Ministry of Information and Communications (MIC). Under Circular 05/2019/TT-BTTTT, telecom equipment including transceivers must meet strict electromagnetic compatibility (EMC) regulations. When importing optical modules directly from Shenzhen into HCMC ports (like Cat Lai Port or Tan Son Nhat International Airport Cargo Terminal), enterprises must ensure their suppliers provide comprehensive certification compliance. Equip-Link provides fully documented shipping kits, including Certificate of Origin (CO), Certificate of Quality (CQ), and compliance test sheets, allowing for swift customs clearance via the Vietnam Automated Cargo Clearance System (VNACCS).
A primary challenge for network engineers in HCMC is compatibility lock-in. Equipment providers such as Hirschmann, Moxa, Cisco, and Allied Telesis write specific vendor identifiers inside the EEPROM at bytes 96-127 of the SFP. If the switch firmware reads a non-approved brand code, it immediately disables the port. At Equip-Link, we utilize advanced hardware emulation and compatibility coding. Our engineers systematically analyze the memory maps of target host switches to ensure that our compatible modules—like the Hirschmann Compatible MMF 1310nm 155M or Moxa Compatible SFP-1FEMLC-T—behave identically to OEM transceivers, eliminating software locks and warning logs.
Ho Chi Minh City experiences a tropical climate with average relative humidity exceeding 80% throughout the rainy season and ambient temperatures climbing up to 40°C. In outdoor cabinets, junction boxes, or roadside signaling cases, internal chassis temperatures can spike past 75°C. Standard commercial-grade SFP transceivers (rated 0°C to 70°C) experience severe thermal stress, leading to laser diode degradation, increased bit error rates (BER), and early MTBF failure. Equip-Link provides specialized Industrial Temperature (-40°C to +85°C) modules. These transceivers feature uncooled Fabry-Perot (FP) or Distributed Feedback (DFB) lasers combined with thermal dissipation compounds and gold-plated pins to resist oxidation in damp tropical environments.
For modern network maintenance in large networks like the EVN SPC grid or Metro Line systems, predictive maintenance is essential. We embed Digital Diagnostics Monitoring (DDM) technology (compliant with SFF-8472) into our 155M/622M transceivers. DDM allows local network managers to monitor real-time parameters from their centralized console, including:
