Product Description
The Lantronix TN-SFP-xx25G-xR-S Series 25G SFP28 transceiver modules are designed to install in any SFP28
port allowing for 25G/10GBase-X interfaces to the network via the SFP28 connector. The TN-SFP-xx25G-xR-S
transceivers are Cisco Compliant and are designed for bi-directional serial-optical data communication such as
25G Ethernet at speeds up to 26.5 Gbps.
Lantronix SFP28 modules fully comply with the Multi-Sourcing Agreement (MSA). This compliance allows our
SFP28 modules to be used in all other MSA compliant SFP28 platforms. In addition, Lantronix SFP28 modules
are also Compliant with all Cisco SFP28 based routers and switches, as well as Cisco’s IOS software.
Lantronix SFP28 modules are not Cisco OEM brand modules.
These SFPs are intended for 25G Ethernet and eCPRI for 5G Fronthaul/Backhaul applications. The eCPRI
Interface Specification for the Common Public Radio Interface is an industry cooperation aimed at defining
publicly available specifications for the key internal interface of radio base stations, such as eCPRI connecting the
eCPRI Radio Equipment Control (eREC) and the eCPRI Radio Equipment (eRE) via a “fronthaul transport
network”. See the latest eCPRI specification at http://www.cpri.info/downloads/eCPRI_v_1_1_2018_01_10.pdf.
RRH (Remote Radio Head) are distributed on the towers every few miles in cities and suburban areas. These
RRHs must be connected to baseband units sitting at centralized locations. The connection between the RRUs
and the base station is often called “fronthaul.” While 4G (LTE) uses CPRI (Common Public Radio Interface) as
the fronthaul connection, eCPRI (enhanced CPRI) is becoming an important technology for 5G and Open RAN.
The eCPRI specification is intended to enable efficient and flexible radio data transmission via a packet based
fronthaul transport network such as Ethernet or IP.

Applications
These SFPs are intended for 25G Data Center connectivity, 5G eCPRI Fronthaul and Backhaul, and 25GBase-X
Ethernet applications.
Safety Instructions
When a connector is removed during installation, testing, or servicing, or when an energized fiber is broken, a risk
of ocular exposure to optical energy that may be potentially hazardous occurs, depending on the laser output
power. The primary hazards of exposure to laser radiation from an optical-fiber system are:
•Damage to the eye by accidental exposure to a beam emitted by a laser source.
•Damage to the eye from viewing a connector attached to a broken fiber or an energized fiber.
Danger: Never attempt to view optical connectors that might be emitting laser energy.
Do not power up the laser product without connecting the laser to the optical fiber and putting the cover in
position, as laser outputs will emit infrared laser light at this point.
See the Lantronix SFP page for our full line of SFP transceivers. See the FOA webpage for additional information.

and its supplier(s) specifically disclaim any expressed or implied warranty of fitness for such High Risk Activities.
SFP Unpacking
Before you start installing the TN-SFP-xxx, verify that the package contains one TN-SFP-xxx device and one
Support Postcard. Notify your sales representative immediately if any of the above items is missing or damaged.
Save the packaging for possible future use.
Note: TN-SFP distances, TX power, RX power, and link budgets can be found on Lantronix website. The fiber
optic transmitters on this device meet Class I Laser safety requirements per IEC-825/CDRH standards and
comply with 21 CFR1040.10 and 21CFR1040.11. WARNING: Visible and invisible laser radiation when open. Do
not stare into the beam or view the beam directly with optical instruments. Failure to observe this warning could
result in an eye injury or blindness.
SFP Installation
Cautions
•The SFP module is keyed to only be installed one way. If forced the wrong way, damage may occur.
•Avoid getting dust or other contaminants into the fiber bore of the SFP transceiver module, as this will cause
the optics to not operate properly.
•Clean the optic surfaces of the optical fiber before you plug them back in to the optical bores of another SFP
module. See Fiber Optic Association Cleaning Fiber Optic Connections page.
•Each port must match the wavelength specifications on the other end of the cable, and the cable must not
exceed the specified cable length for reliable communications.
Installing an SFP Module
1. Attach an ESD-preventive wrist strap to your wrist and to an ESD ground connector or bare metal surface on
the chassis.
2. Remove the SFP transceiver module from its protective packaging. Note: Do not remove the optical bore dust
plugs until directed to do so in a later procedure.
3. Check the slot orientation; some slots are “upside down” compared to other slots.
4. Position the SFP device at the desired installation slot, with the label facing correctly.
5. Carefully slide the SFP device into the slot, aligning it with the internal installation guides.
6. Ensure that the SFP device is firmly seated against the internal mating connector. To verify that the SFP is
seated and latched properly. a) Grasp the SFP by the sides and try to remove it without releasing the latch. b)
If the SFP cannot be removed, it is installed and seated properly. If the SFP can be removed, reinsert it and
press harder with your thumb; repeat if necessary until it is latched securely into the socket.

7. Connect the fiber cable to the fiber port connector of the SFP device. Make sure the SFP release latch is in
the up (closed) position when you insert the cable connector into the SFP.
8. Remove the dust plug from the connector. Save the dust plug for future use.
9. Attach an appropriate cable into the SFP module port.
10. Attach the other end of the cable into the other device.
11. Observe the status LED(s). See the related manual for details.
TN-SFP-BX40-U-I TN-SFP-BX40-D-I
Fiber Cable Physical Characteristics
The fiber cable physical characteristics must meet or exceed IEEE 802.3ae specifications:
•Single mode fiber (recommended): 9 μm
•Multimode fiber (recommended): Distance up to 100m on 50/125 OM4 multimode fiber, up to 70 m for 50/125
um OM3 multimode fiber
Warning: Visible and invisible laser radiation when open. DO NOT stare into laser beam or view directly with
optical instruments. Failure to observe this warning could result in damage to your eyes or blindness.
Connecting Fiber Cables
To install the fiber cable:
1. Locate the appropriate fiber cable.
2. Install the cable as shown right.

33815 Rev. C https://www.lantronix.com/ Page 9 of 16
Removing an SFP Module
Caution: Be careful when removing the SFP or SFP+ from a device. Some SFP transceiver module
temperatures may exceed 160°F (70°C) and be too hot to touch with bare hands. Note: Do not remove and
replace the SFP modules more often than necessary; excessive SFP removing and replacing can shorten the
SFPs useful life.
1. Attach an ESD-preventive wrist strap to your wrist and to the ESD ground connector or a bare metal surface
on your chassis.
2. For future reattachment of fiber-optic cables, note which connector plug is send (TX) and which is receive
(RX).
3. Remove the SFP transceiver module:
a. If the SFP transceiver module has an actuator button latch, gently press the actuator button on the front
of the SFP transceiver module until it clicks, and the latch mechanism releases the SFP transceiver module
from the socket connector. Grasp the actuator button between your thumb and index finger, and carefully pull
the SFP transceiver module straight out of the module slot.
b. If the SFP transceiver module has a bail clasp latch, pull the latch out and down to eject the SFP
transceiver module from the socket connector. If the bail clasp latch is obstructed and you cannot use your
index finger to open it, use a small, flat-blade screwdriver or other long, narrow instrument to open the bail
clasp latch. Grasp the SFP transceiver module between your thumb and index finger, and carefully remove it
from the socket.
4. Replace the Dust Plug.
5. Place the removed SFP/SFP+ transceiver module in an antistatic bag or other protective package.
