100G QSFP28 BX40 4x 25G NRZ 1309.14nm-TX/1304.58nm-RX 40km Simplex LC/APC Industrial Module, Arista

The 100G QSFP28 BX40 4x 25G NRZ 1309.14nm-TX/1304.58nm-RX 40km Simplex LC/APC Industrial Module, Arista is a QSFP28 optical transceiver delivering 100Gbps over SMF. Operating at 1309.14nm-TX/1304.58nm-RX with a Simplex LC/APC interface, it reaches 40km and is compliant with QSFP28 MSA, 100G Lambda MSA, SFF‑8636, IEEE 802.3bs, CAUI‑4. Built-in digital diagnostics give real-time access to operating parameters, making the module easy to deploy and maintain in 100G Ethernet, data center interconnect and 5G transport networks.

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/APC Industrial Module, Arista delivers 100Gbps transmission over SMF with a reach of 40km. The Simplex LC/APC interface and 1309.14nm-TX/1304.58nm-RX 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 4x 25G-NRZ modulation, which keeps it aligned with current 100G switch silicon.

Standards compliance covers QSFP28 MSA, 100G Lambda MSA, SFF‑8636, IEEE 802.3bs, CAUI‑4. The unit works in any equipment with a standard QSFP28 interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.

To order, quote QSFP-BX40-100G-I 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.

Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.

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.

From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.

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.
