In enterprise access, campus, telecom edge and industrial network environments, the 1G SFP GLC-BX-U 10km 1310nm-TX/1490nm-RX Simplex LC/UPC Module, Cisco delivers 1.25Gbps transmission over SMF with a reach of 10km. The Simplex LC interface and 1310nm-TX/1490nm-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-BX-U directly.

On the compatibility side, this unit is the practical equivalent of the Cisco part GLC-BX-U and works in Cisco systems out of the box. Standards compliance covers Fast Ethernet, Gigabit Fibre Channel, MSA Compliant.

To order, quote SFP-1G34-BX10 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.

Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.

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.

Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.

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.
