About Shanghai Mars Industrial

Shanghai Mars Industrial Co., Ltd. supplies optical transceivers and related connectivity hardware to network integrators, telecom operators, data centre builders and equipment manufacturers. Trading under the MARS brand, the company works from Shanghai and covers a range that runs from 155M and 1.25G SFP modules through 10G SFP+, 25G SFP28, 40G QSFP+ and 100G QSFP28 optics, and continues into copper RJ45 SFP modules, direct attach copper and active optical cables, fibre media converters and ethernet switches. The catalogue is organised by rate and form factor so that a buyer can move from a link requirement to a short list of candidate models without reading through unrelated product families.

Most orders begin as a configuration question rather than a part number. A buyer describes the host platform, the port type, the fibre or copper plant already installed and the reach the link has to cover, and the specification is confirmed in writing before anything is built or coded. Modules are programmed for the host platform they will sit in, and that coding is treated as part of the confirmed configuration rather than a detail settled after production. Sample quantities are normally used to validate a link in the customer's own equipment before a production quantity is released.

Price, lead time and packaging are quoted against that confirmed configuration, and the same document records the test data, the warranty term and the compliance paperwork that travel with the shipment. The company sells business to business and supports OEM and ODM work, including neutral packaging and customer labelling. Host platform names are used only to describe the equipment a module is coded for; MARS is an independent supplier and is not affiliated with, approved by or endorsed by any switch or router manufacturer.

What we do

From product engineering to after-sales.

Product engineering and coding

Selection work starts from the link rather than the catalogue. The host platform, software version, port type, fibre or copper plant, reach and operating temperature are collected and turned into a candidate specification, and any gap between what the buyer has described and what the optics can deliver is raised before a quotation is issued. Each module carries programmed identification data that the host reads at insertion, so the coding target is recorded on the order alongside the optical specification. Where a customer runs mixed platforms, the same optical build is coded per platform so that one part list can serve several equipment families.

Production and assembly

Modules are assembled to the relevant multi-source agreement for the form factor, which governs the mechanical envelope, the electrical interface and the management interface the host expects. Optical sub-assemblies, driver and receiver circuits, housings and cages are brought together on a build that is released only against a confirmed configuration, so a production run reflects the specification the buyer signed off rather than a generic stock item. Build records identify the lot, the components used and the coding applied. Assembly is carried out in controlled conditions appropriate to optical work, with handling procedures covering electrostatic protection and connector cleanliness.

Testing and quality control

Every module is tested before it is packed. Optical output power, receiver sensitivity, extinction ratio and wavelength are measured against the datasheet limits for the model, and the digital diagnostic values the module reports are checked against those measurements so that the monitoring a network team relies on is trustworthy. Coded modules are seated in a host of the target platform to confirm that they are read, brought up and reported correctly. Test results are retained by lot, which allows a question raised months later to be traced back to the measurements taken at the time of build.

Packaging and logistics

Modules ship in individual anti-static packaging inside cartons sized for the quantity ordered, with neutral packaging and customer labelling available for OEM and ODM work. Packing lists identify model, coding, quantity and lot so that a receiving warehouse can reconcile a delivery without opening every box. Export documentation is prepared for the declared configuration, and shipments move by courier, air or sea according to the quantity and the delivery date agreed. Where a project is phased, releases can be scheduled against the project programme rather than sent as a single consignment.

After-sales and documentation

Each order is supported by the paperwork a buyer needs to accept it: datasheet, test data for the lot, packing list and the compliance documentation applicable to the confirmed configuration. If a module does not come up in the host, the first step is diagnostic rather than commercial, because a link fault, a patch lead, a port setting and a coding mismatch present differently and are separated by the diagnostic values the module reports. Warranty handling, replacement and return routing are set out in the quotation, and the technical contact who handled the configuration stays with the account.

Quality approach

Tested before it ships.

Quality control for pluggable optics is mostly a question of catching variation early, because a module that fails after installation costs far more than one rejected on the bench. The flow therefore begins at goods-in, where optical sub-assemblies and electrical components are checked against the specification they were purchased to, and continues through coding verification, full optical parameter measurement and temperature screening before packing. Each module is measured individually rather than sampled, and the digital diagnostic values it reports are compared with the instrument readings so that the figures a network team will see in their own management system match what was measured in production. Samples are retained from each production lot, and the lot number printed on the label ties a delivered module back to its components, its coding target, its test record and its retained sample. That chain is what makes a field question answerable rather than a matter of opinion.

Milestones

How we got here.

  1. 2013

    Company established in Shanghai

    The business is founded in Shanghai as a supplier of pluggable optical transceivers to network integrators and equipment resellers. Early work centres on 155M and 1.25G SFP modules for access networks, surveillance links and campus Ethernet, with selection support offered alongside supply from the outset.

  2. 2016

    Coding and testing brought in house

    Module programming and optical parameter testing are established as in-house operations rather than outsourced steps, allowing coding targets to be confirmed per platform and test data to be retained by lot. The range extends into 10G SFP+ optics and copper RJ45 SFP modules for mixed fibre and copper deployments.

  3. 2019

    Range extended to 40G and 100G

    QSFP+ and QSFP28 optics are added for data centre aggregation and spine links, together with direct attach copper and active optical cables for short in-rack and inter-rack connections. Temperature screening is formalised as a standard production step across both commercial and industrial grades.

  4. 2022

    OEM and ODM programme formalised

    Neutral packaging, customer labelling and per-platform coding are consolidated into a defined OEM and ODM service with documented configuration sign-off. Media converters and ethernet switches are added so that an access link can be supplied as a set rather than as separate purchases from separate suppliers.

  5. 2025

    25G SFP28 and export documentation

    25G SFP28 optics are added for mobile fronthaul and server access, bringing the catalogue to its current twelve categories. Export documentation, test data issue and warranty handling are standardised across the range so that a buyer in any market receives the same paperwork set with a shipment.

Milestone dates are provisional pending confirmation.

FAQ

Working with us.

Do you support OEM and ODM work?

Yes. OEM and ODM work covers per-platform coding, customer part identification, custom labelling and neutral or customer-branded packaging, and it can extend to reach, wavelength, connector and temperature grade variants within a product family. The configuration is documented and signed off before production, and the agreed identification data is verified on every unit at the coding check. Artwork, label formats and packaging dimensions are confirmed in the same document as the optical specification.

What is the minimum order quantity?

There is no single figure across the range. Standard configurations held in stock can be supplied in sample quantities so that a link can be validated before a production order is placed. Custom coding, non-standard reach or wavelength combinations, industrial temperature grades and customer packaging carry a higher minimum because they are built to order, and that minimum is stated in the quotation for the specific configuration rather than applied as a blanket rule.

How does the quotation process work?

Send the host platform and model, software version, port type, required rate and reach, fibre or copper type, connector and temperature grade, along with the quantity and delivery date. Anything missing is raised as a question rather than assumed. The quotation states the confirmed configuration, the coding target, unit price, lead time, packaging, warranty term and the compliance documentation included, so that what is being priced is unambiguous before an order is placed.

What documentation is provided with an order?

Each shipment is accompanied by the model datasheet, the test data for the lot, a packing list identifying model, coding, quantity and lot reference, and the compliance documentation applicable to the confirmed configuration. Commercial and export paperwork is prepared for the declared goods. Certificate scope is model specific, so the documents that apply to a particular build are identified in the quotation rather than described in general terms.
