Applications
Built for enterprise access, campus, telecom edge and industrial network environments, this SFP module carries 1.25Gbps over SMF up to 80km per link. The Duplex LC interface and 1550nm 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-ZX-SM-RGD.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the Cisco part GLC-ZX-SM-RGD and works in Cisco systems out of the box. Standards compliance covers SFF-8472 MSA Compliant, IEEE 802.3ah-2004.
Ordering Information
Our part number for this module is SFP1G-ZX-55-I. 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.
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.
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.
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.
