Description
The Avago Technologies AFBR-89CDDZ 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 interoper-
ability up to 100m over an 8-fi ber (or 12-fi ber) MPO opti-
cal 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 inter-
face with 802.3 Clause 91 RS-FEC.
Per channel transmitter and receiver retimers, confi gured
for 4x25G operation, can be bypassed to enable alterna-
tive data rate transmission.
These modules are designed to operate over multimode
fi ber 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-fi -
ber (or 12-fi ber) MPO connector. This module incorpo-
rates Avago Technologies proven integrated circuit and
VCSEL technology to provide reliable long life, high per-
formance, and consistent service.
