Optical Transceiver Module
OPCW-MX1-85-CBT datasheet
Block Diagram of Transceiver
This product is a parallel Quad Small Form-factor Pluggable (QSFP28) optical module that supports 100GBASESR4 Ethernet and OTU4 applications. It provides increased port density and total system cost savings. The
QSFP28 full-duplex optical module offers 4 independent transmit and receive channels, each capable of up to
28Gb/s operation for an aggregate data rate of up to 112Gb/s on 100 meters of OM4 multi-mode fiber.
An optical fiber ribbon cable with an MTP/MPO connector can be plugged into the QSFP28 module receptacle.
Proper alignment is ensured by the guide pins inside the receptacle. The cable usually cannot be twisted for
proper channel to channel alignment. Electrical connection is achieved through an MSA-compliant 38-pin edge
type connector.
The module operates by a single +3.3V power supply. LVCMOS/LVTTL global control signals, such as Module
Present, Reset, Interrupt and Low Power Mode, are available with the modules. A 2-wire serial interface is
available to send and receive more complex control signals, and to receive digital diagnostic information.
Individual channels can be addressed and unused channels can be shut down for maximum design flexibility.
The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to
the QSFP28 Multi-Source Agreement (MSA). It has been designed to meet the harshest external operating
conditions including temperature, humidity and EMI interference. The module offers very high functionality and
feature integration, accessible via a two-wire serial interface.
This product converts parallel electrical input signals into parallel optical signals, by a driven Vertical Cavity
Surface Emitting Laser (VCSEL) array. The transmitter module accepts electrical input signals compatible with
Common Mode Logic (CML) levels. All input data signals are differential and internally terminated. The receiver
module converts parallel optical input signals via a photo detector array into parallel electrical output signals. The
receiver module outputs electrical signals are also voltage compatible with Common Mode Logic (CML) levels. All
data signals are differential and support a data rates up to 28Gb/s per channel. Figure 1 shows the functional
block diagram of this product.

100Gbps QSFP28 SR4 OTN
Optical Transceiver Module
OPCW-MX1-85-CBT datasheet
A single +3.3V power supply is required to power up the module. Both power supply pins VccTx and VccRx are
internally connected and should be applied concurrently. As per MSA specifications the module offers 7 low
speed hardware control pins (including the 2-wire serial interface): ModSelL, SCL, SDA, ResetL, LPMode,
ModPrsL and IntL.
Module Select (ModSelL) is an input pin. When held low by the host, the module responds to 2-wire serial
communication commands. The ModSelL allows the use of multiple QSFP28 modules on a single 2-wire
interface bus – individual ModSelL lines for each QSFP28 module must be used.
Serial Clock (SCL) and Serial Data (SDA) are required for the 2-wire serial bus communication interface and
enable the host to access the QSFP28 memory map.
The ResetL pin enables a complete module reset, returning module settings to their default state, when a low
level on the ResetL pin is held for longer than the minimum pulse length. During the execution of a reset the host
shall disregard all status bits until the module indicates a completion of the reset interrupt. The module indicates
this by posting an IntL (Interrupt) signal with the Data_Not_Ready bit negated in the memory map. Note that on
power up (including hot insertion) the module should post this completion of reset interrupt without requiring a
reset.
Low Power Mode (LPMode) pin is used to set the maximum power consumption for the module in order to
protect hosts that are not capable of cooling higher power modules, should such modules be accidentally
inserted.
Module Present (ModPrsL) is a signal local to the host board which, in the absence of a module, is normally
pulled up to the host Vcc. When a module is inserted into the connector, it completes the path to ground through
a resistor on the host board and asserts the signal. ModPrsL then indicates a module is present by setting
ModPrsL to a “Low” state.
Interrupt (IntL) is an output pin. Low indicates a possible module operational fault or a status critical to the host
system. The host identifies the source of the interrupt using the 2-wire serial interface. The IntL pin is an open
collector output and must be pulled to the Host Vcc voltage on the Host board.

Notes:
1. GND is the symbol for signal and supply (power) common for QSFP28 modules. All are common within the
QSFP28 module and all module voltages are referenced to this potential unless otherwise noted. Connect
these directly to the host board signal common ground plane.
2. VccRx, Vcc1 and VccTx are the receiver and transmitter power suppliers and shall be applied concurrently.
Recommended host board power supply filtering is shown in Figure 4 below. Vcc Rx, Vcc1 and Vcc Tx may be
internally connected within the QSFP28 transceiver module in any combination. The connector pins are each
rated for a maximum current of 1000mA.

Optical Receptacle Cleaning Recommendations :
All fiber stubs inside the receptacle portions were cleaned before shipment. In the event of contamination
of the optical ports, the recommended cleaning process is the use of forced nitrogen. If contamination is
thought to have remained, the optical ports can be cleaned using a NTT international Cletop® stick type and
HFE7100 cleaning fluid. Before the mating of patch-cord, the fiber end should be cleaned up by using
Cletop® cleaning cassette.
