ESCRIPTION
The Small Form-Factor Pluggable GPON OLT 2.5G/
1.25G, 20 km (SFP) is specifically designed for the
Gigabit Passive Optical Network (GPON) Optical Line
Terminal (OLT) application facilitating high perfor-
mance, integrated, bidirectional data transmission
over one, single mode optical fiber.
The SFP incorporates a 1490 nm DFB laser diode for
streaming 2.5 Gigabit downstream data and an APD/
TIA burst mode receiver for 1310 nm 1.25 Megabit
upstream data
The SFP supports the following features:
♦
SC Simplex receptacle
♦
Hot pluggable
♦
Wavelength
◊
Transmit: 1490 nm
◊
Receive: 1310 nm
♦

Due to compliance certification requirements, only
SFPs supplied by ADTRAN are to be used with the
host module. ADTRAN cannot certify system integrity
with other SFPs.

NSTALLATION
Prior to installation, inspect the SFP. If damage has
occured during shipping, file a claim with the carrier,
and then contact ADTRAN Customer Support. For
more information, refer to “Warranty”.
To install the SFP into an appropriate module,
complete the following steps:
1. Insert the SFP into the SFP cage on the circuit
board of the host module with the latch handle
facing outward. Slide the SFP all the way into the
cage.
NOTE
The latch on the SFP is for removal only. When
removing the SFP, rotate the latch away from the
SFP, the SFP should slide easily out of the cage.
2. Exert adequate pressure to ensure the SFP is
completely seated in the SFP cage.
3. Do not remove the connector plug until the
optical fiber connection is made.
It is recommended that the connector plug remain on
whenever the transciever optical fiber connector is
not inserted.
4. Continue the installation and turn-up of the host
module using the instructions in the Job Aid
provided with the module, or using the
Installation and Maintenance Practice (I&M)
available online at
www.adtran.com.
P
ROVISIONING
The SFP is not directly provisionable. To provision the
SFP, access the menu system of the host module.
Refer to the “Provisioning” section of the Job Aid or
Installation and Maintenance Practice provided with
the host module for provisioning details.
