The Avago Technologies AFBR-89CEDZ is a Four-Channel, Pluggable, Multi-mode, Fiber-Optic QSFP28 transceiver for 100 Gigabit Ethernet Applications. This transceiver is a high performance module for short-range multi-lane data communication and interconnect applications. It integrates four data lanes in each direction with each lane operating at 25.78125 Gbps, giving an aggregated bandwidth of 103.125 Gbps. It allows optical interoperability up to 300m over an 8-fiber (or 12-fiber) MPO optical multi-mode OM4 cable. The pull tab facilitates the insertion and extraction of these transceivers in high density environment. Each electrical lane operates at 25.78125 Gbps and conforms to the 100GE CAUI4 interface with 802.3 Clause 91 RS-FEC. Per channel transmitter and receiver retimers, configured for 4x25G operation, can be bypassed to enable alternative data rate transmission. These modules are designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The electrical interface uses a 38 contact QSFP28 edge type connector. The optical interface uses a conventional 8-fiber (or 12-fiber) MPO connector. This module incorporates Avago Technologies proven integrated circuit and VCSEL technology to provide reliable long life, high performance, and consistent service.
