AFBR-8420Z
CFP2, 850 nm, 100GBASE-SR10 Compliant
Pluggable 100G Ethernet Optical Transceiver
Product Brief
Description
Avago Technologies’ AFBR-8420Z CFP2 SR10 is a ten
channel pluggable, parallel, fiber optic transceiver for
100Gbps Ethernet Applications. The transceiver supports
high speed serial links over multi-mode fiber at signaling
rates up to 103.125Gb/s (a serial line rate of 10.3125Gb/s
per channel) for link distances up to 100m with OM3 fiber
or 150m with OM4 fiber. The product is compliant with the
CFP2 industry agreement for mechanical and low speed
electrical specifications. High speed electrical and optical
specifications are compliant with IEEE 802.3ba Clause 86
for 100GBASE-SR10 media, Clause 86A for CPPI electrical
interface, and Clause 45 for MDIO.
The transceiver electrical interface uses a 104 contact
edge type connector, as specified in the CFP2 industry
agreement. The optical interface uses a 24-fiber MTP®
(MPO) fiber optic connector. This transceiver incorporates
Avago Technologies proven integrated circuit and VCSEL
technologies to provide reliable, high performance and
consistent service.
Digital diagnostic monitoring information (DMI) is present
in the AFBR-8420Z per the CFP2 industry agreement,
providing real time monitoring information of transmitter,
receiver and module operating conditions over the MDIO
interface.
