Applications
Built for 100G Ethernet, data center interconnect and 5G transport networks, this QSFP28 module carries 103.125Gbps over SMF up to 60km per link. With its Duplex LC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request. The link runs 4x 25G-NRZ modulation, which keeps it aligned with current 100G switch silicon.
Standards and Compatibility
This product is designed and tested to comply with QSFP28 MSA, IEEE 802.3ba, RoHS-10 compliant. It plugs into any standards-based QSFP28 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
Ordering Information
To order, quote QSFP-eER4-100G together with your quantity. Stock items ship quickly; for OEM orders we support custom labels, retail packing and vendor-specific coding, all handled in our own factory.
Quality and Testing
Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.
Packing Details
Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.
Customization Service
Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.
Worldwide Delivery
We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.
