Industrial-grade 155M/622M optical modules fully verified for interoperability with Moxa, Hirschmann, Cisco, and major legacy network switches.
As Vietnam's premier economic hub, Ho Chi Minh City (HCMC) is undergoing a massive industrial transition. From the high-tech automation lines at Saigon Hi-Tech Park (SHTP) to the vital maritime logistics nodes in Cat Lai Port, reliable data communication is the backbone of this transformation. While modern data centers push toward 100G and 800G, legacy industrial networks, power grids, and railway control systems continue to rely on the rock-solid reliability, low power consumption, and deterministic performance of 155M and 622M SFP (Small Form-factor Pluggable) optical modules.
These legacy systems, functioning on SDH (Synchronous Digital Hierarchy) STM-1 / STM-4 or Fast Ethernet standards, are critical for utility networks such as the Ho Chi Minh City Power Corporation (EVNHCMC) substation SCADA systems. In these environments, communication reliability is paramount, and high-frequency, high-speed alternatives are often less resilient to EMI (Electromagnetic Interference) and extreme thermal fluctuations than legacy fiber topologies.
155M optical modules provide EMI-immune fiber connections connecting smart grid protection relays over long distances (up to 80km) back to regional dispatch centers in HCMC.
For the Ben Thanh - Suoi Tien urban transit system, 622M SFP transceivers play a vital role in transmission networks running CBTC (Communication-Based Train Control) signals.
Harsh industrial operating temperature SFP modules (-40°C to 85°C) link Moxa and Hirschmann switches in manufacturing lines, overcoming tropical heat and moisture.
Globally, the market for 155M and 622M SFPs remains exceptionally stable, driven by the massive installed base of industrial Ethernet equipment and telecommunications access networks. Industry trends focus primarily on the optimization of these legacy footprints:
Critical infrastructure is built to last 15 to 30 years. Modernizing an entire substation or railway line to 10G just to transport sub-megabit SCADA telemetry is cost-prohibitive. Thus, 155Mbps (STM-1/OC-3) and 622Mbps (STM-4/OC-12) transceivers act as a crucial bridging technology. They permit network administrators to prolong the utility of existing field equipment while transitioning the physical fiber layer to support modern security protocols.
WaveLink Optoelectronics supports this lifecycle by manufacturing compatible transceivers that meet the exact requirements of legacy legacy systems, ensuring zero packet loss and seamless integration.
When selecting 155M/622M SFP modules for the HCMC climate and industrial applications, engineers must analyze crucial optical parameters to guarantee link budgets and uptime. Below is the operational technical roadmap of our optical transceiver portfolio:

In the past year, the company launched approximately 180 new product models, supported by a research team of around 220 engineers, continuously driving innovation in high-speed optical communication technologies.
Designing robust link architectures that resist environmental factors and protocol mismatches in regional network rollouts.
In high-voltage environments like the EVNHCMC transformer stations, optical isolation prevents ground loop currents. Our 155M singlemode 40km/80km SFPs establish direct lines between local sensors, telemetry relays, and central SCADA dashboards, surviving heavy EMI spikes caused by switching activity.
For modern metros, passenger safety systems demand isolated signal paths. SFP transceivers running over redundant rings guarantee zero-packet-loss transport for passenger gates, ticketing machines, emergency intercom lines, and the automated signaling infrastructure across the HCMC transit corridors.
At maritime hubs like Cat Lai Port, outdoor switch boxes are exposed to extreme humidity, sea spray, and direct heat. WaveLink's industrial-grade modules, equipped with enhanced physical gold fingers and hermetically sealed optical diodes, prevent standard oxidation failures and support 24/7 port logistical systems.
