Optical Modules Bridge Compatibility Gap in Data Centers to Increase Bandwidth
Wed, 02/29/2012 - 11:18am
Avago Technologies announced fiber optic module solutions that are said to enable more efficient switching and greater bandwidth in data centers. The new pluggable, parallel optical QSFP+ eSR4 transceiver addresses both 40 Gigabit (40G) and 10 Gigabit (10G) Ethernet applications with a verified link distance of 400 m. This gives data center operators the flexibility to reuse the current 10G wired infrastructure when upgrading to 40G. The QSFP+ eSR4 modules integrate four 10G lanes in each direction to increase bandwidth within a line card by more than three times while using 50 percent less power than that of a one-lane SFP+ module, according to the company. The modules can be used to develop top-of-rack, blade and modular switches with up to 44 QSFP+ ports per line card. This provides 176 10G-channels with QSFP+. QSFP+ eSR4 modules can be used for both high-density 10G and 40G aggregated Ethernet applications.
