ADTRAN QSFP28 CWDM4 Quick Start

ESCRIPTION
The QSFP28 CWDM4 transceiver is used in 100 Gbps links over
single mode fiber. The QSFP28 integrates four channel CWDM
DFB lasers and multiplexes them into a single channel for 100
Gbps optical transmission.
The receiving side of the module de-multiplexes the 100 Gbps
optical signal into four CWDM channels. Each channel operates
at 25 Gbps and the module is able to operate at 100 Gbps up to 2
km using 9/125 μm Single Mode Fiber (SMF).
The QSFP28 is compliant with 100G and IEEE 802.3ba
standards.

NSTALLATION
Before installation, inspect the QSFP28. If damage has occurred
during shipping, file a claim with the carrier, and then contact
ADTRAN Customer Support. For more information, refer to
"Warranty".

Installation Guidelines

The following are guidelines for this installation.
■ The latch on the QSFP28 is for removal only. When removing
the QSFP28, rotate the latch away from the QSFP28. The
QSFP28 should slide easily out of the cage.

Installation Steps

To install the QSFP28, complete the following steps:
1. Insert the QSFP28 into the QSFP28 cage on the circuit
board of the host module with the latch handle facing out-
ward. Slide the QSFP28 all the way into the cage.
2. Exert adequate pressure to ensure the QSFP28 is
completely seated in the QSFP28 cage.
3. Do not remove the protective dust cover until the optical fiber
connection is made.
4. Continue the installation and turn-up of the host module.
