Applications
The 1G SFP GLC-BX80-D 80km 1570nm-TX/1490nm-RX Simplex LC/UPC Module, Cisco is used in enterprise access, campus, telecom edge and industrial network environments, where it provides a 1.25Gbps link over SMF up to 80km. The Simplex LC interface and 1570nm-TX/1490nm-RX optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. For networks standardized on Cisco hardware, it is a drop-in equivalent of the GLC-BX80-D.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the Cisco part GLC-BX80-D and works in Cisco systems out of the box. Standards compliance covers Fast Ethernet, Gigabit Fibre Channel, MSA Compliant.
Ordering Information
Order this product as SFP-1G5749-BX80. Common models are stocked for fast dispatch. We can supply the module with neutral or customer-branded labels, and compatibility coding for a specific equipment vendor can be added at no extra process step.
Quality and Testing
Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.
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.
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.
How We Ship
Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.
