The CWDM-SFP-1370-40-C is a Cisco-compatible 1000Base-CWDM SFP transceiver operating at 1370 nm, supporting Gigabit Ethernet links up to 40 km over single-mode fiber.
It supports a maximum link length of 40 km on single-mode fiber with an optical budget of approximately 21 dB.
This module operates at a nominal central wavelength of 1370 nm in compliance with the CWDM ITU-T grid.
The module supports a data rate of 1.25 Gbps (1000Base-CWDM) for Gigabit Ethernet applications.
It requires single-mode fiber (SMF, 9/125 µm) terminated with LC connectors.
Yes, the CWDM-SFP-1370-40-C is hot-swappable, allowing plug-and-play installation without powering down the switch or router.
Yes, it is fully Cisco-compatible and interoperability tested with Cisco switches and routers.
It uses a duplex LC connector, standard for SFP CWDM transceivers.
The module operates reliably between 0 °C and 70 °C (commercial grade).
Yes, it meets Multi-Source Agreement (MSA) specifications for SFP form factor and electrical interface.
It provides an optical power budget of up to 21 dB (Tx power: 0 to +4 dBm; Rx sensitivity: –22 dBm).
Ideal applications include campus backbone, metro networks, data center interconnects, and CWDM ring topologies.
Insert the module into an SFP port until it clicks, then connect LC-terminated single-mode fiber patch cables to the Tx/Rx ports.
No special cables are required—standard LC–LC single-mode fiber cables are compatible.
It is backed by a one-year limited warranty covering defects in materials and workmanship.
Verify correct wavelength pairing, inspect fiber cleanliness, check LC connections, and confirm link parameters in the network switch.
