TN-SFP-xxx

Small Form Factor Pluggable
(SFP)
Transceiver Modules

The Transition Networks TN-SFP-xxx
series small form factor pluggable (SFP)
transceiver modules are designed to
install in any SFP port, connect
multimode 1000Base-SX or single mode

1000Base-LX fiber-optic cable to the
network through the SFP connector. The TN-SFP-xxx transceivers are designed for bi­directional serial-optical data communications such as Gigabit Ethernet or fiber channel
at speeds up to 1.25 Gbps.

*Unless otherwise indicated, the distances listed
are the typical maximum cable distance. The
actual maximum cable distances are dependent
upon the physical characteristics of the network
installation.

Installation

Important: In Cisco Systems' literature, Cisco switches with SFP slots do not accept
SFP modules from other manufacturers. The Cisco switch identifies the manufacturer’s
ID along with the part number and blocks operations to the port for non-Cisco
modules. Other major SFP switch manufacturers do not indicate in their literature that
such restrictions are imposed.

Installing the SFP transceiver

To install the SFP module into a media converter, do the following:

1. Position the module at the installation slot with the label faces up.

2. Slide the module into the slot fully to ensure proper connection.

Installing the fiber cable

To install the fiber cable, do the following:

1. Locate 1000Base-SX-compliant or 1000Base-LX-compliant fiber cable with
male TX to RX connectors installed at both ends.

2. Install the fiber cable as shown below.

**Install simplex or single-fiber models in pairs in the same network where one is the
local SFP and the other is the remote SFP.

*Unless otherwise indicated, the distances listed are the typical maximum cable distance.
The actual maximum cable distances are dependent upon the physical characteristics of
the network installation.

Diagnostic Monitoring Interface (DMI)

The following DMI port screen and explanation table contains brief definitions of the
DMI support offered on Transition Networks SFP optical interfaces. For further
information, please see the help option on the CPSMM-xxx SNMP agent or Focal
Point, Transition Networks' GUI.

Variable Name Description

DMI Rx Power Measured Receive optical power in microwatts and in decibels

relative to 1mW.

DMI Rx Power Alarm Alarm status of measured receive optical power.

DMI Temp Internally measured temperature of transceiver in degrees C

and degrees F.

DMI Temp Alarm Alarm status for internally measured temperature of the

transceiver.

DMI Bias Current Measured transmit bias current in microamperes.

DMI Bias Alarm Alarm status for measured transmit bias current for the

interface.

DMI Tx Power Measured transmit power in microwatts and in decibels

relative to 1mW.

DMI Tx Power Alarm Alarm status of measured transmit power.

Rx Power Intrusion
Threshold

Instructs the converter to stop passing traffic when the receive
power drops below the new threshold. This feature is
sometimes referred to as 'Intrusion Detection,' since tapping
into a fiber to intercept traffic leads to a reduction in receive
power. This value can be entered in microwatts or in decibels
relative to 1mW.

Note: This feature is not available on all devices.
