Bel RJ45 Copper SFP Transceivers Selection Guide Applications Host Interface IEEE Spec Operating Temperature Cable SFP-1GBT-05 BCM54616S 10/100/1000Base-T SGMII Compliant IEEE 802.3ab, u -40°C + 85°C Cat5/5e (Note 1) SFP-1GBT-06 BCM54616S 1000Base-X to 1000Base-T GBIC Compliant IEEE 802.3ab -40°C + 85°C Cat5/5e (Note 2) Part Number Broadcom Chipset Note 1: 2 or 4 pair: 10Base-T Full or Half Duplex, 100Base-T Full or Half Duplex, 1000Base-T Full or Half Duplex Note 2: 4 pair: 1000 Mbps FAQ for Quick Installation Q: Is a specific firmware required for installing Bel’s Copper SFP Transceivers? A: No, if the MAC is either SGMII or GBIC compliant with Auto-Negotiation ENABLE, simply plug in the RJ45 connector to the SFP Transceivers. Then, insert it into the SFP cage of the system host. Q: What if the MAC is currently hosting other vendors’ SFP Transceivers with their related firmware? A: Bel’s SFP Transceivers will not recognize the firmware that is R/W for other vendors such as Finisar, Avago, etc. MAC should be reset to its original state of SGMII or GBIC compliant to make sure that Auto-Negotiation is ENABLE and other firmware is purged from the system host. Then, simply install Bel’s SFP Transceivers as described above. Q: Can the SFP Transceiver be programmed to switch between the two interfaces such as SGMII or GBIC? A: Yes, by accessing the PHY registers and following the detailed instructions in the datasheet. However, we recommend that you select each SFP part number for a dedicated interface. ©2012 Bel Fuse Inc.
