SSR-GLX70-01-AA and SSR-GLH39-02

The following table lists the media specifications for the SSR-GLX70-01-AA and SSR-GLH39-02 (T-Series) line cards.

Table 35. SSR-GLX70-01-AA and SSR-GLH39-02 Media Specifications

Port Type	Specification

1000BASE-LX	• 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-GLX39-02on page 110
	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.

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.
