Rail Transit PIS Solution
Onboard and station passenger information for metro, high-speed rail and light rail
N+1 hot standby, up to 10 km uncompressed over single fiber
In rail, the metric is not bandwidth
It is never going down — there is no reboot button in a moving train
Four hard constraints on rail projects
- Equipment cannot stop while trains run: failover has to be automatic
- Station to tunnel and train to control center distances exceed what copper covers
- Heat, vibration and dust in cars kill commercial-grade hardware
- Assets spread along the whole line: without network management, every check is a site visit
Our approach
- N+1 hot standby: the N+1 backup HDMI matrix switches automatically when the primary path fails
- 10 km over one fiber: the OPS optical transceiver is uncompressed and reaches 10 km on single-mode
- Multi-signal fusion: the PIS transceiver carries HDMI plus 2 x RS232 plus 2 x audio on one fiber, 1/4/8/16 channels
- SNMP management: the managed OPS transceiver reports status centrally
Signal Chain
Playout, transport, onboard, display
centralised management
up to 10 km single fiber
vibration-resistant mounting
synchronised playout
video and notices
Specify N+1 redundancy at station level. For onboard and tunnel sections keep transport uncompressed over fiber, which also cuts the amount of cable in cars and tunnels.

FAQ
How does the N+1 switchover work?
When the primary path fails the system switches to standby automatically, with no operator action. Switchover time depends on the project configuration; we provide the details during tendering.
What can travel over a single fiber?
The multi-channel models carry one HDMI AV channel plus two RS232 control channels and two stereo audio channels on one fiber, which reduces cabling inside cars and tunnels.
How far can it go?
Up to 10 km on single-fiber single-mode as standard. Longer distances can be customised for a project.
Can the equipment meet rail certifications?
We are the manufacturer. Test reports and certifications required by a specific project follow the tender documents and are supplied against that list. Industrial design features such as wide temperature range, vibration resistance and metal chassis can be confirmed per project.
Is there fault alarming?
The managed transceivers support SNMP, so line-wide device status is visible on the central NMS platform and fewer site visits are needed.
