Applications
In 100G Ethernet, data center interconnect and 5G transport networks, the 100G QSFP28 BX40 4x 25G NRZ 1309.14nm-TX/1304.58nm-RX 40km Simplex LC/UPC Module, Cisco delivers 106.25Gbps transmission over SMF with a reach of 40km@OS2. With its Simplex LC/UPC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment. The link runs 4x 25G-NRZ modulation, which keeps it aligned with current 100G switch silicon.
Standards and Compatibility
Compliance: QSFP28 MSA, IEEE 802.3bs, 100G Lambda MSA. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.
Ordering Information
Our part number for this module is QSFP-BX40-100G. When ordering, just let us know the quantity and whether you need the compatibility coding for a particular switch brand; labeling and packaging can also follow your channel requirements.
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.
Our Testing Process
Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.
Package
Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.
Built to Your Spec
Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.
