Cisco Part Number: SFP-10G-BX40U-I= Spare is a Cisco 10GBASE-BX40-U Bidirectional for 40km
Cisco SFP+ modules provide an array of features and advantages:
- They boast the industry’s most compact 10G form factor, ensuring optimal density per chassis.
- These modules are hot-swappable, meaning they can be inserted or replaced in an Ethernet SFP+ port on a Cisco switch without requiring a shutdown.
- They support a “pay-as-you-populate” model, allowing for investment protection and seamless technology migration.
- With digital optical monitoring capability, users benefit from robust diagnostic capabilities.
- They offer optical interoperability with 10GBASE XENPAK, 10GBASE X2, and 10GBASE XFP interfaces on the same link.
- The Cisco quality Identification (ID) feature enables Cisco platforms to discern whether the module has undergone certification and testing by Cisco, ensuring quality and reliability.
Cisco SFP-10G-BX40D-I and SFP-10G-BX40U-I (for 40Km single-fiber bidirectional applications)
The Cisco SFP-10G-BX40D-I and SFP-10G-BX40U-I SFPs operate on a single strand of standard SMF.
A SFP-10G-BX40D-I device is always connected to a SFP-10G-BX40U-I device with a single strand of standard SMF with an operating transmission range up to 40 km.
The communication over a single strand of fiber is achieved by separating the transmission wavelength of the two devices. SFP-10G-BX40D-I transmits a 1330-nm channel and receives a 1270-nm signal. The SFP-10G-BX40U-I transmits at a 1270-nm wavelength and receives a 1330-nm signal.
The SFP-10G-BX40D-I and SFP-10G-BX40U-I SFPs support Digital Optical Monitoring (DOM) functions according to the industry-standard SFF-8472 Multisource Agreement (MSA). This feature gives the end user the ability to monitor real-time parameters of the SFP, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.
