Manufacturer profile for buyers evaluating FIBERSHOW as a factory-direct optical networking supplier.
Who we are
Shenzhen Shengxinlian Electronics Co., Ltd. (盛鑫联) designs and manufactures optical communications equipment in Shenzhen, China. FIBERSHOW is our export brand; the public catalog lives at optshow.com.
Since 2005 we have kept R&D, production, quality control, and after-sales under one roof. We sell factory-direct to distributors, system integrators, and industrial project buyers. OEM / white-label programs are available when partners need their own brand on labels, packaging, or firmware strings.
What we make
Our catalog focuses on practical fiber transport for industrial and telecom edge networks:
- Industrial Ethernet / fiber switches — managed and unmanaged, PoE options, fiber uplinks
- Media converters — 100M / 1G / 10G, mini and card-type, industrial and selected hardened series
- Copper SFP / SFP+ — electrical transceiver modules for copper runs (not a full optical-module product line)
- Protocol / specialty fiber gear — RS485/422, CAN, serial-to-fiber, and related terminals where listed
Public product and datasheet model numbers on this site start with SUN- (including documented SUN-GY-* codes). Quotes and packing lists use the same export SKUs unless an OEM label program is agreed on the RFQ.
Where products are used
Typical deployments include utility and substation networks, industrial automation, wind and solar sites, CCTV / access backbones, campus and ISP edge links, and other sites that need stable fiber conversion and switching.
We regularly support buyers and project teams across the Middle East, India, Eastern Europe, Southeast Asia, and Africa—markets where clear lead times, industrial temperature options, and straightforward OEM terms matter as much as the datasheet.
How we sell
- RFQ-primary — this site is a B2B catalog and quote desk, not a consumer checkout storefront
- Factory direct — one manufacturer for quoting, production, and Shenzhen shipment
- OEM / white-label — private branding for distributors and system houses
- Industrial options — wide-temperature and hardened designs where the SKU supports them
- Flexible MOQ & lead time — stock and build-to-order paths; confirm on each RFQ
- Honest compliance — certificates and test reports are supplied on request / via RFQ; we do not publish unverified certificate scans on the public site
