The GLC-BX40-DA-I-C is a Cisco-compatible, single-fiber SFP transceiver supporting 1 Gbps transmission over distances up to 40 km at 1490 nm wavelength.
This module supports a data rate of 1000 Mbps (1 Gbps), ensuring gigabit Ethernet connectivity for network uplinks and switches.
It provides reliable single-fiber transmission over distances up to 40 km, ideal for metropolitan area networks and long-distance links.
The module transmits at 1490 nm and receives at 1310 nm, enabling bidirectional communication on a single fiber strand.
Yes, it is fully Cisco-compatible and interoperable with most Cisco switches and routers that support 1000BASE-BX SFP modules.
Yes. The GLC-BX40-DA-I-C is hot-swappable, allowing you to insert or remove it without powering down the network device.
Yes. It supports DOM, providing real-time monitoring of optical power, temperature, voltage and laser bias current.
The module is MSA-compliant (Multi-Source Agreement) and meets IEEE 802.3ah 1000BASE-BX standards for single-fiber Gigabit Ethernet.
It requires single-mode fiber (SMF) with an ITU-T G.652.D specification to achieve optimal performance over 40 km.
Standard versions operate from 0 °C to 70 °C; extended-temperature variants cover -40 °C to 85 °C for harsh environments.
Yes. As an MSA-compliant module, it interoperates seamlessly with other certified SFP transceivers in multi-vendor environments.
Simply align the module with the SFP port, push it in until it clicks, and confirm link status via your device’s interface or LED indicator.
Yes. It typically includes a one-year limited warranty covering manufacturing defects and performance issues under normal use.
Verify fiber polarity, check DOM diagnostics for power levels, inspect connectors for damage, and confirm correct wavelength pairing.
Single-fiber reduces cabling costs by using one strand for transmit and receive, simplifies installation and conserves fiber infrastructure.
Unlike multi-mode modules, it uses single-mode fiber for long-reach links up to 40 km, offering higher bandwidth and lower attenuation.
