SFP-1G-LX-Dell-BCC | Dell Compatible 1GB Single-Mode 10km (1000BASE-LX)

Q: Will this work in place of the Dell SFP-1G-LX or 407-BBOO?
A: Yes. This transceiver is fully compatible with both Dell part numbers SFP-1G-LX and 407-BBOO. It conforms to the IEEE 802.3z 1000BASE-LX standard and uses the same SFP form factor, 1.25 Gbps data rate, 1310nm wavelength, and LC connector. It is plug-and-play compatible and will function identically to the original Dell modules.

Q: Which Dell switches and networking equipment support this transceiver?
A: This transceiver works in Dell PowerConnect, PowerSwitch, and Networking S-series switches with Gigabit Ethernet SFP ports that support 1000BASE-LX. This includes models such as PowerConnect N2000, N3000, N4000 series, PowerSwitch S5224F-ON, S4048-ON, and S5000 series platforms. Any Dell switch with a standards-compliant SFP port supporting 1000BASE-LX will accept this module.

Q: What type of fibre cable is required and what distances are supported?
A: This transceiver requires single-mode fibre (SMF) with 9/125 micron core and uses LC duplex connectors. On standard G.652 single-mode fibre, it supports distances up to 10km. If used with multimode fibre (OM1, OM2, OM3), the maximum reach is reduced to 550 metres and requires a mode conditioning patch cable on the transmitter side to prevent modal noise.

Q: How do I access the DOM diagnostic data from this transceiver?
A: The transceiver implements SFF-8472 Digital Diagnostic Monitoring via the I2C two-wire serial interface at address A2h. Most Dell switches expose DOM parameters through CLI commands or SNMP-based network management tools. You can monitor real-time transmit and receive optical power, temperature, supply voltage, and laser bias current to detect degrading links or failing optics before service disruption.

Q: Can I mix this transceiver with original Dell transceivers on the same switch?
A: Yes. Because this transceiver conforms to the IEEE 802.3z and SFP MSA standards, it operates identically to the Dell-branded module and can be mixed freely in the same switch or across different switches in a link. The 1000BASE-LX standard defines the electrical and optical specifications, ensuring full interoperability regardless of transceiver vendor as long as both ends meet the standard.
