MF-27WXC Series
2.5Gbps SFP TRANSCEIVER MODULE
2.7Gbps Multi-Rate CWDM SFP Transceiver with Digital Diagnostic
Monitoring Interface MF-27WXC Series
1. Description
This transceiver is compliant with Small
Form-factor Pluggable (SFP) MSA, and
optimized for 155Mbps to 2.7Gbps Coarse
Wavelength Division Multiplexing (CWDM)
applications.
The optical subassembly consists of two parts,
the transmitter with an uncooled DFB laser in
a hermetic sealed coaxial module, the receiver
with a PD preamp in a hermetic sealed coaxial
module and integrated circuits for reshaping
received optical signals.
The built-in serial ID recognition is
incorporated, which allows users to interface
with two wire serial interface that displays
information on manufacturer, part number,
link, distance, and other parameters.
The Digital Diagnostic Monitoring interface is
incorporated, which monitors transceiver
parameters including Temperature, Supply
voltage, Laser bias current, Laser power and
Received optical power.

This is the power supply pin for the Receiver part.
It should be connected to +3.3V.
Recommended power supply decoupling. (See Figure 8)
* Both TX Vcc and RX Vcc have been internally connected due to supply of
control circuit Vcc.
This data input pin modulates the laser diode. When the TD+ input is asserted, the
laser diode is turned on.

They are internally AC-coupled into an equivalent load of RI differential, as shown
in Figure 8.

Active high TTL input, with internal 7.4k ohm pull-up resistor to Vcc.
Asserting the transmitter disable will deactivate the laser within the assert time.
Table 1 indicates the timing of TX_DISABLE.

Received Data Out and Inverted Received Data Out are differential serial output
from the receiver.
These are AC-coupled 100 ohm differential lines which should be terminated with
a 100 ohm (differential) at the user SERDES, as shown in Figure 8. AC coupling is
done inside the module and is thus not required on the host board.
Active high open collector/drain output that indicates a loss-of-signal condition
(LOS). When the average optical power received by the module is below the
Assert Level, RX_LOS is indicated.
Table 1 indicates the timing of RX_LOS. RX_LOS requires a 4.7k to 10k ohm
pull-up resistor external to the module, i.e., in the host system Host_Vcc, as shown
in Figure 8.
The pull-up voltage is between 2.0 V and VccR (VccT) + 0.3 V.
Active high open collector/drain output that indicates a fault in the module. This
can be failure of the laser diode. Under this condition, TX_FAULT will activate
and be latched. And then the laser will be deactivated within the assert time.
TX_FAULT also requires a 4.7k to 10k ohm pull-up resistor externally, i.e. in the
host system Host_Vcc, as shown in Figure 8.

MOD_DEF
[0:2]
-
This module has a serial ID function, which provides information about the
transceiver’s capabilities, standard interfaces, manufacturer and other information.
This function is provided via a two wire serial EEPROM interface.
MOD_DEF[0] is connected to ground inside the module. (LOW)
MOD_DEF[1] is the serial clock signal input. (SCL)
MOD_DEF[2] is the data output/input. (SDA)
They should be pulled up with 4.7Kohm -10Kohm resistor on the host board.
The pull-up voltage shall be VccT or VccR.
The serial ID definitions are as given in the “SFP-MSA” standard. See Figure 9.
These pins defined the bandwidth filters. 7pin/9pin setting=[*/*]:
[0/0]: Full bandwidth, [1/0]: 1.25Gbps, [0/1]: 622Mbps, [1/1]: 155Mbps
These input pins are internally pulled down to GND with 33Kohm resistor.
If this function is not used, both pins should be left open or connected to GND.

Safety Cautions for Use of Optoelectronic Devices
General:
Although the manufacturer is always striving to improve the reliability of its product, problems and errors may occur with semiconductor products.
Therefore, the user's products are required to be designed with full safety regard to prevent any accidents that result in injury, death, fire or
environmental damage even when semiconductor products happen to error. Especially it is recommended to take in consideration about redundancy, fire
prevention, error prevention safeguards. And the following requirements must be strictly observed.
Warning!
1. Eye safety : Semiconductor laser radiates laser light during operation. Laser light is very dangerous when shot directly into human eyes. Don't look
at laser light directly, or through optics such as a lens. The laser light should be observed using the ITV camera, IR-viewer, or other appropriate
instruments.
2. Product handling : The product contains GaAs (gallium arsenide). It is safe for regular use, but harmful to the human body if made into powder
or steam. Be sure to avoid dangerous process like smashing, burning, chemical etching. Never put this product in one's mouth or swallow it.
3. Product disposal : This product must be disposed of as special industrial waste. It is necessary to separate it from general industrial waste and
general garbage.
Handling Cautions for Optoelectronic Devices
1. General:
(1) The products described in this specification are designed and manufactured for use in general communication systems or electronic devices, unless
their applications or reliability are otherwise specified. Therefore, they are not designed or manufactured for installation in devices or systems that
may affect human life or that are used in social infrastructure requiring high reliability.
(2) When the customer is considering to use the products in special applications, such as transportation systems (automobiles, trains, vessels), medical
equipments, aerospace, nuclear power control, and submarine repeaters or systems, please contact Mitsubishi Electric or an authorized distributor.
2. Shipping Conditions:
(1) During shipment, place the packing boxes in the correct direction, and fix them firmly to keep them immovable. Placing the boxes upside down,
tilting, or applying abnormal pressure onto them may cause deformation in the electrode terminals, breaking of optical fiber, or other problems.
(2) Never throw or drop the packing boxes. Hard impact on the boxes may cause break of the devices.
(3) Take strict precautions to keep the devices dry when shipping under rain or snow.
3. Storage Conditions:
When storing the products, it is recommended to store them following the conditions described below without opening the packing. Not taking
enough care in storing may result in defects in electrical characteristics, soldering quality, visual appearance, and so on. The main points are described
below (if special storage conditions are given to the product in the specification sheet, they have priority over the following general cautions):
(1) Appropriate temperature and humidity conditions, i.e., temperature range between 5~30°C, and humidity between 40~60 percent RH, should be
maintained in storage locations. Controlling the temperature and humidity within this range is particularly important in case of long-term storage for
six months or more.
(2) The atmosphere should be particularly free from toxic gases and dust.
(3) Do not apply any load on the product.
(4) Do not cut or bend the leads of the devices which are to be stored. This is to prevent corrosion in the cut or bent part of the lead causing soldering
problems in the customer’s assembling process.
(5) Sudden change in temperature may cause condensation in the product or packing, therefore, such locations should be avoided for storing.
Temperature in storage locations should be stable.
(6) When storing ceramic package products for extended periods of time, the leads may turn reddish due to reaction with sulfur in the atmosphere.
(7) Storage conditions for bare chip and unsealed products shall be stated separately because bare chip and unsealed products require stricter controls
than package sealed products.
4. Design Conditions and Environment under Use:
(1) Avoid use in locations where water or organic solvents adhere directly to the product, or where there is any possibility of the generation of corrosive
gas, explosive gas, dust, salinity, or other troublesome conditions. Such environments will not only significantly lower the reliability, but also may
lead to serious accidents.
(2) Operation in excess of the absolute maximum ratings can cause permanent damage to the device. The customers are requested to design not to exceed
those ratings even for a short time.
5. ESD Safety Cautions:
The optoelectronic devices are sensitive to static electricity (ESD, electro-static discharge). The product can be broken by ESD. When handling this
product, please observe the following countermeasures:
<Countermeasures against Static Electricity and Surge>
To prevent break of devices by static electricity or surge, please adopt the following countermeasures in the assembly line:
(1) Ground all equipments, machinery jigs, and tools in the process line with earth wires installed in them. Take particular care with hot plates, solder
irons and other items for which the commercial power supplies are prone to leakage.
(2) Workers should always use earth bands. Use of antistatic clothing, electric conductive shoes, and other safety equipment while at work is highly
recommended.
(3) Use conductive materials for this product’s container, etc.
(4) It is recommended that grounding mats be placed on the surfaces of assembly line workbench and the surrounding floor in work area, etc.
(5) When mounting this product in parts or materials which can be electrically charged (printed wiring boards, plastic products, etc.), pay close attention
to the static electricity in those parts. ESD may damage the product.
(6) Humidity in working environment should be controlled to be 40 percent RH or higher. These countermeasures are most general, and there is a need to
carefully confirm the line before starting mass production using this product (in the trial production, etc.). It is extremely important to prevent surge,
eliminate it rapidly, and prevent it from spreading.
