Cabling and Connector Specifications
The following table lists the media specifications for the SSR-GLX70-01-AA and SSR-GLH39-02
(T-Series) line cards.
Port Type
1000BASE-LX
Optics
Receiver Sensitivity
Minimum
Maximum
Note: The maximum power for this unit (24 dB) is greater than the maximum input power;
therefore, a long cable length or an attenuator is required.

Table 35. SSR-GLX70-01-AA and SSR-GLH39-02 Media Specifications
Specification
• 802.3z standard (also uses 802.3x for flow control)
• SC-style Media Interface Connector (MIC); either connection pin in the
MIC can be used for transmit or receive; see SSR-GLX39-02
for attaching cables
• 9.5 micron single mode fiber-optic cable
• Maximum 70 kilometers (229,659 feet) segment length for 10 micron
SMF fiber-optic cable
• Minimum cable length is 50 kilometers (164,041 feet) segment length for
10 micron SMF fiber-optic cable
Note: If you do not use the minimum cable length the receiver will
oversaturate. The minimum distance depends on the attenuation of
the specific cable used. Enterasys recommends using at least 50Km
of cable or calculating the cable attenuation to be greater than 3dB.
The maximum transmitter output is +5dBm and the maximum
allowed input power is -3dBm. In this worst case scenario, you
would need to attenuate the signal at least 8dB.
