Applications
In OTN transport, carrier metro and long-haul aggregation networks, the 100G QSFP28 ZR BiDi DCO 80km DWDM C-band Tunable Coherent Module, Cisco delivers 100Gbps transmission over SMF with a reach of 80km (unamplified)300km (amplified). The Duplex LC/UPC interface and 1528.77~1566.72nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment. The link runs NRZ modulation, which keeps it aligned with current 100G switch silicon.
Standards and Compatibility
This product is designed and tested to comply with SFF-8661 Rev.2.5, QSFP-DD MSA Rev 7.1, Type 2A, IEEE 802.3-2022, IEEE 802.3-2022 100GBASE-ZR, CMIS Rev5.2. 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
Our part number for this module is QSFP-ZRBD-100G-S. 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.
OEM and Custom Orders
We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.
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.
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.
