Applications
Built for CWDM metro access, enterprise and telecom edge networks, this SFP module carries 1000Mbps over SMF up to 40km per link. With its Duplex LC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. It is interoperable with Cisco platforms and replaces the Cisco part CWDM-SFP-1270 directly.
Standards and Compatibility
Compliance: SFP MSASFF-8472. For projects standardized on Cisco hardware, this product replaces the CWDM-SFP-1270 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 CW-SFP1G40-27. 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.
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.
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.
Our Testing Process
Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.
Packaging
Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.
