Applications
Built for enterprise access, campus, telecom edge and industrial network environments, this SFP module carries 1.25Gbps over SMF up to 40km per link. The Simplex LC interface and 1490nm-TX/1310nm-RX optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. It is interoperable with Cisco platforms and replaces the Cisco part GLC-BX40-DA directly.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the Cisco part GLC-BX40-DA and works in Cisco systems out of the box. Standards compliance covers Fast Ethernet, Gigabit Fibre Channel, MSA Compliant.
Ordering Information
To order, quote SFP-1G43-BX40 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.
Tested Before Shipment
We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.
Packaging Options
Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.
Custom-made Fiber Products
As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.
Shipping and Lead Time
Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.
