AFBR-7QERxxZ 40 Gigabit Ethernet & InfiniBand QDR QSFP+ Pluggable, Parallel Active Optical Cable Data Sheet Description Features The Avago Technologies AFBR-7QERxxZ is a Four- Compliant to the 40GBASE-SR4 and XLPPI Specification Channel, Pluggable, Parallel, Fiber-Optic QSFP+ Active per IEEE 802.3ba-2010 and supporting 40G-IB-QDR/ Optical Cable (AOC) solution for 40 Gigabit Ethernet 20G-IB-DDR/10G-IB-SDR applications Applications. This AOC is a high performance cable for Compliant to the industry standard SFF-8436 QSFP+ short-range multi-lane data communication and inter- Specification connect applications. It integrates four data lanes in each Power Level 1: Max Power < 1.5 W direction with 40 Gbps aggregate bandwidth. Each lane can operate at 10.3125 Gbps. These cables also support High port density: 21 mm horizontal port pitch 4 10G InfiniBand QDR applications and are backwards Operate at 10.3125 Gbps per channel with 64b/66b compatible to the 4 5G IB DDR and 4 2.5G IB single IB encoded data for 40GbE application and at 10 Gbps SDR applications. with 8b/10b compatible encoded data for 40G-IB-QDR application These Active Optical Cables operate over multimode fiber systems using a nominal wavelength of 850 nm. The elec- 0 to 70 C case temperature operating range trical interface uses a 38 contact edge type connector. This Proven High Reliability 850 nm technology: Avago AOC incorporates Avago Technologies proven integrated VCSEL transmitter and Avago PIN receiver circuit and VCSEL technology to provide reliable long life, Hot pluggable for ease of servicing and installation high performance, and consistent service.

For AOC interrogation and control, the control in- terface (LVTTL compatible) incorporates a Two Wire Serial Transmitter (TWS) interface of clock and data signals. Rx LOS and Rx Squelch are available through the TWS interface. The optical transmitter portion of the AOC (see Figure 1) incorporates 4 VCSELs (Vertical Cavity Surface Emitting Flags are set and interrupts generated for Rx loss of optical Laser), input buffer and laser drivers and control & bias input signal (LOS).
