What are the different transceiver types that have made the GBIC obsolete?
What will be an ideal response?
ANSWER: Newer transceivers that have made the GBIC obsolete include:
* SFP (small form-factor pluggable)-Provides the same function as GBICs and is more compact, allowing more ports per linear inch. Also known as mini GBICs or SFP GBICs. Typically used for 1 Gbps connections, but theoretically capable of 5 Gbps.
* XFP (10 Gigabit small form-factor pluggable)-Supports up to 10 Gbps and is slightly larger than SFP with lower power consumption than SFP+.
* SFP+-Developed later than XFP and is the same module size as SFP; theoretical maximum transmission speed is 16 Gbps.
* QSFP (quad small form-factor pluggable)-Complies with the 802.3ba standard, squeezing four channels in a single transceiver and supporting data rates up to 40 Gbps (4 x 10 Gbps).
* QSFP+-Generally the same technology as QSFP while supporting data rates over 40 Gbps. Highest speed format currently is QSFP28 with a total theoretical maximum data rate of 112 Gbps (4 x 28 Gbps).
* CFP (centum form-factor pluggable)-Intended for 100-Gbps network connections, with each succeeding generation (CFP, CFP2, CFP4) becoming smaller and more energy-efficient. Centum is Latin for 100.
