Q: What will the microQSFP (Micro Quad Small-Form-Factor Pluggable) MSA address and the microQSFP specification define? (Optical interfaces and copper?) A: The microQSFP MSA will develop a specification for a new compact module form factor, microQSFP, and make the specification available to the industry to promote industry adoption of compatible products that can be used […]

FAQ about 40G Optical Network
Q. What is the 40GbE max supported distances? A. The IEEE 40GBASE-X standard describes the following: 40GBASE-SR4 supports up to 100m on OM3, and 150m on OM4. There is no support for OM2 or OM1 (these are considered legacy). 40GBASE-LR4 supports up to 10km on 9um SM fiber (same fiber used for 10G single mode […]
IEEE 802.3 forms study groups for 25, 50 and 100/200 Gbit/sec Ethernet
The Ethernet Alliance recently commended the decision to form three study groups within IEEE 802.3. The groups are exploring the development of standards for 25-Gbit/sec Ethernet over singlemode fiber, 50-Gibt/sec Ethernet over a single lane, and next-generation 100- and 200-Gbit/sec Ethernet. The Ethernet Alliance commented that by forming these groups, IEEE 802.3 is “demonstrating Ethernet’s […]
