Questions & Answers
Q
What is the Cisco GLC-BX40-DA-I 1000BASE-BX40 SFP (1490 nm)?
A
The Cisco GLC-BX40-DA-I is a single-fiber, bidirectional 1 Gbps SFP transceiver that transmits at 1490 nm and receives at 1310 nm over single-mode fiber for up to 40 km.
Q
What transmission distance does the GLC-BX40-DA-I support?
A
The GLC-BX40-DA-I supports single-mode fiber links up to 40 kilometers at 1 Gbps data rates.
Q
Which wavelength does the 1000BASE-BX40 SFP use for TX and RX?
A
It transmits data at 1490 nm (TX) and receives data at 1310 nm (RX) on a single strand of single-mode fiber.
Q
Is the GLC-BX40-DA-I hot-swappable?
A
Yes. The transceiver is IEEE 802.3z-compliant and hot-swappable, allowing insertion and removal without powering down the switch or router.
Q
What fiber type and connector are required?
A
The module requires ITU-T G.652 single-mode fiber and uses an LC duplex connector for single-fiber bidirectional operation.
Q
What digital diagnostics are available?
A
It supports SFF-8472 digital optical monitoring for real-time readouts of optical power, temperature, voltage and laser bias current.
Q
Which Cisco platforms support the GLC-BX40-DA-I?
A
This SFP is compatible with Cisco Catalyst, Nexus and ASR series switches and routers that provide standard SFP slots.
Q
What is the typical power consumption?
A
The transceiver typically consumes less than 1 W of power during operation.
Q
How do I install the 1000BASE-BX40 SFP?
A
Simply insert the LC connector into the module, slide the SFP into a compatible slot, and verify link status on the switch or router.
Q
Does the GLC-BX40-DA-I require special configuration?
A
No. Most Cisco devices auto-detect the module; manual configuration is rarely needed unless link parameters must be customized.
Q
What is the operating temperature range?
A
The device operates between 0 °C and 70 °C (32 °F to 158 °F) in standard ambient conditions.
Q
Can I mix the GLC-BX40-DA-I with other SFP modules?
A
Yes, but ensure all modules share the same specifications (wavelength, distance, fiber type) to maintain link integrity.
Q
Does this SFP include a warranty?
A
Cisco provides a limited lifetime warranty on the GLC-BX40-DA-I against manufacturing defects under normal use.
Q
Is the GLC-BX40-DA-I compatible with third-party SFP cages?
A
It functions in third-party SFP slots that accept Cisco-branded modules, though full diagnostics may require Cisco IOS support.
Q
What is the link budget for the 1000BASE-BX40 module?
A
With a transmitter output of up to 0 dBm and minimum receiver sensitivity of -26 dBm, the link budget exceeds 26 dB for 40 km.
Q
How can I verify the SFP is functioning correctly?
A
Use the ‘show interface transceiver detail’ command on Cisco devices to view diagnostic metrics such as optical power and temperature.
