SFP-1G-SX-Dell-BCC | Dell Compatible 1GB Multi-Mode 550m (1000BASE-SX)

Q: Will this work in place of the Dell SFP-1G-SX, 407-BBOR, 407-10587, or 407-BCDU?
A: Yes. This module is fully compatible with all four Dell part numbers. It conforms to the 1000BASE-SX standard (IEEE 802.3z) and the SFP MSA specification, delivering the same 1.25 Gbps data rate, 850nm wavelength, and LC connector interface. It is plug-and-play compatible with Dell switches, routers, and servers that support SFP Gigabit Ethernet ports.

Q: Which Dell platforms are compatible with this transceiver?
A: This transceiver is compatible with Dell Networking switches and servers that feature SFP Gigabit Ethernet ports conforming to the SFP MSA standard. This includes Dell Networking S-series, N-series, X-series, and PowerConnect platforms, as well as PowerEdge servers with SFP network interface cards. Compatibility is determined by the host device supporting standard 1000BASE-SX SFP modules, not by specific model restrictions.

Q: What fibre type and length does this module support, and how does OM3 or OM4 differ from OM1?
A: This module requires multi-mode fibre and operates at 850nm. On OM2, OM3, or OM4 fibre (50/125um core), it supports transmission up to 550m. On older OM1 fibre (62.5/125um core), the maximum reach is limited to 220m due to higher modal dispersion. OM3 and OM4 fibres are laser-optimized with lower attenuation and better bandwidth characteristics, enabling longer reach and higher reliability for 1G SX links compared to OM1.

Q: Does this transceiver support Digital Diagnostic Monitoring, and what parameters can be monitored?
A: Yes, this module includes full DOM (DDM) functionality. It provides real-time access to five key operating parameters: transmitted optical power, received optical power, module temperature, laser bias current, and supply voltage. These diagnostics are accessible via the MSA-compatible EEPROM interface and can be read by most network management systems supporting SNMP or vendor CLI tools, enabling proactive fault isolation and link budget monitoring.

Q: Can this transceiver be used in the same switch alongside SFP+ 10G modules or other SFP form factors?
A: Yes, in most cases. This 1G SFP module can coexist with SFP+ 10G modules in compatible switch platforms that support mixed-rate operation. The SFP and SFP+ form factors share the same physical footprint and electrical interface, and many Dell switches auto-negotiate the data rate per port. However, confirm that the specific switch model supports mixed SFP and SFP+ operation, as some older platforms may have restrictions or require ports to be grouped by speed.
