Data Center :
Upgrading server-switch links from 1G to 10G, forces switch uplinks to jump to 40G connecting top-of-rack to end-of-row and aggregation switch layers. As data center operators emerge from the economic recession, budgets are still very tight and "incremental upgrades" are the way operators are buying. Adding 10G/40G links "as needed" is the current buying practice. While "100G" seems to get all the trade show and press coverage, 40G is where the money is for the next 2-3 years. Data centers are just hitting the need for about 4-6G - not yet 10G; so many data centers are in a transitional, upgrade-as-needed state. The Google, Facebook, Microsoft etc. so called Mega Data Centers at $1 billion a piece do not represent the main stay of the data center although they garner a lot of attention and awe.
Chasing this transceiver opportunity, multiple transceiver suppliers have jumped at offering 40G QSFP SR transceivers and Ethernet AOCs for < 50 meters. Over 10 transceiver companies announced transceivers and AOCs and more suppliers are coming! Technical barriers to entry are low and cost sensitive Internet Data Centers (especially in China) are likely to gobble these up in volume. LightCounting expects the transceiver industry will do its traditional pricing act of "Let's all cut our own throats on price and see who bleeds to death last ". As a result 40G SR parts are likely to see a very rapid price drop from about $250 today to under $190 for fully compliant OEM prices next year. We even have seen "plug & hope they-play" parts at $65 - you get what you pay for! OEM prices for Ethernet AOCs can be found below at $190 - and that is for a complete link with both end and fiber! But at 25G signaling, the multi-mode fiber reach looking like 25m. Similarly, on the circuit boards 25G signaling shrinks trace length from 10-12" at 10G to 4-6 inches at 25G and will bring to popularity Embedded optical modules (EOMs) for mid-board use interconnecting rack internal electronics together.
The 40G QSFP MSA has a unique position of supporting short reach (SR) ~100 meters with multi-mode fibers or 10Km with duplex, single-mode fiber - all in the same QSFP switch port. Companies such as ColorChip, Sumitomo, and a few others offer LR4 QSFP parts and Opnext, NeoPhotonics, Finisar, InnoLight, etc. offer larger CFP devices. QSFP enables 36-44 per line card compared to only 4 CFP. Running at 32 Watts, at LightCounting we affectionately refer to the CFP as the "Compact Frying Pan" and although popular in telecom, it is not in datacom! OEM prices range from $2,000 to $3,500 depending on data center or telecom features.
