Applications
Network architects choose the 1G SFP MGBBX1 20km 1310nm-TX/1490nm-RX Simplex LC/UPC Module, Cisco for enterprise access, campus, telecom edge and industrial network environments: it runs 1.25Gbps over SMF and reaches 20km. With its Simplex LC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. For networks standardized on Cisco hardware, it is a drop-in equivalent of the MGBBX1.
Standards and Compatibility
Compliance: Fast Ethernet, Gigabit Fibre Channel, MSA Compliant. For projects standardized on Cisco hardware, this product replaces the MGBBX1 directly, with identical fit and function. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.
Ordering Information
Order this product as SFP-1G34-BX20. 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.
Delivery
Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.
Reliability Control
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.
Package
Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.
OEM and Custom Orders
We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.
