10G MSM Family on page 26-1
OC-192c Triple Mode Family on page 26-6
UNIPHY Family on page 26-12

10G MSM Family

The 10G MSM load module family consists of a UNIPHY LM Load module which supports SONET and Ethernet at 10G rates. Modes supported on this board include POS, WAN, and LAN. For POS there is additional feature support such as DCC, RPR, and SRP.

Figure 26-1 on page 26-2 displays the 10G MSM module.

Figure 26-1. MSM10G1-02 Load Module

Note: Due to power requirements, only one MSM module can be used in a 250 or 400T chassis. Other modules can be used with the MSM in the same chassis, but only one CPM1000T8 at a time (except the CMP1000T8 module, which has the same limitation).

Part Numbers

The MSM family part numbers are shown in Table 26-2.

On the MSM10G, there is only one packet group mode (wide packet groups) . Two different scenarios apply: 3If sequence checking is enabled, then the number of packet group IDs is limited in this way: 3When Wide Bin Mode (on the Wide Packet Groups page) is not enabled = 65536. 3When Wide Bin Mode is enabled = 524288. 3If sequence checking is not enabled, then the number of packet group IDs is limited in this way: 3When Wide Bin Mode (on the Wide Packet Groups page) is not enabled = 65536. 3When Wide Bin Mode is enabled = 2097152.

Port LEDs

Each 10G MSM port incorporates a set of LEDs, as described in the following table.

Table 26-4. 10G MSM Port LEDs

LED Label	Usage
LASER ON	Green when the port's laser is turned on. Blank otherwise.
Pause	Green when transmit is paused, blank when powered off.
PPP/Link	Green in link up condition, Red in link down condition, blank indicates loopback mode enabled.
Tx	Green if transmit is active and frames are being sent, blank otherwise.
LOS	Green when signal level is good, Red when loss of signal occurs, blank if no transceiver detected.
Option	N/A
Trigger	Green when Trigger A condition occurs, Red for Temperature Fault, blank otherwise.
Error	Red when module in error state (fault condition), blank otherwise.
Rx	Green indicates valid receive frames, Red indicates errored frames received, blank when no frames received.
LOF	Green when valid framing occurs, Red when Loss of Frame occurs.

Clock In/Out

The load module provides coaxial connectors for clock input and clock output to allow the DUT to phase-lock with the interface. When running off an external clock, the clock input signal must meet the requirements listed in Table 26-5 to ensure proper performance of the load module.

Table 26-5. Clock Input Specifications

Parameter	Characteristic
Connector	SMA
Frequency	SONET: 155.52 MHz ±20ppm 10GE: 161.132 MHz ±-100ppm
Amplitude	1.1 Vpp minimum, into 50 W, AC coupled
Duty cycle	40 to 60%

The clock in/out electrical interface parameters are defined in Table 26-6.

Table 26-6. Clock Output Specifications

Parameter	Characteristic
Connector	SMA
Frequency	SONET: 155.52 MHz ±20ppm 10GE: 161.132 MHz ±-100ppm
Amplitude	500m Vpp minimum, 600 Vpp typical into 50 W
Duty cycle	40 to 60%

The load module contains a phase-locked loop (PLL) that reduces the jitter of the input clock, either from the internal or external clock source. The bandwidth of the PLL is approximately 1kHz.

Trigger Out

The signals and LEDs available on the trigger out pins for these cards are described in Table 26-7.

Table 26-7. 10G MSM Trigger Out Signals

Pin/LED	Value
Trigger Out	10nS active high pulse on trigger
Trigger LED	Indicates Trigger, Pause Frame received in 10GE mode.

Statistics

Statistics for 10G MSM cards, under various modes of operation may be found in Table B-25 on page B-135.

OC-192c Triple Mode Family

The OC-192c Triple Mode family of load modules implements Optical Carrier interfaces that run at OC192 speeds. The interface operates in concatenated mode, as opposed to channelized mode. One of the modules in this family (the LMOC192cPOS) is shown in Figure 26-2.

Figure 26-2. LMOC192c Load Module

Part Numbering

The OC192 cards come with a number of options. All part numbers are of the form:

LMOC192HTOS or

LMFOC192HTOS

where H is the hundreds designator, T is the tens designator, O is the ones designator, and S is the suffix.

LMF boards have no fiber optic interface. It allows for quick validation of serializer and deserializer designs for WAN Packet over SONET/SDH products operating at the STS-192c/STM-64 level. The LMF interface is a 300 pin MegaArray BERG connector, which is an industry standard MSA interface and is compliant per OIF1999.102.8, SFI-4 specification. A reference clock can be supplied through this interface ranging in frequency from 25 MHz to 622 MHz.

The part numbers for these load modules are shown in Table 26-8. Items without a Price List Names entry are no longer available.

1Refer to the LMOC192cPOS and LMOC192cBERT columns for the characteristics of this card when its port is in POS or BERT mode, respectively. 2The inter-frame gap is indirectly controlled by the frame rate. 3Streams are divided up into three categories: 144 slow speed streams, 8 medium streams and 8 fast streams.

The Ixia VSR modules, which were developed in accordance with the OIF Implementation Agreement VSR-1, use twelve parallel multimode fiber optic lines operating at 1.25Gbps per channel, instead of existing 1310nm or 1550nm serial optics. VSR optics are designed to drive signals over distances less than 300 meters, which is sufficient for interconnecting devices within a service provider's Point-of-Presence (POP). Over these short distances, VSR optics offer a significant cost savings compared to intermediate and long-reach serial lasers.

When performing latency measurements, the following restrictions apply:

If latency is measured with packets that are smaller than 80 bytes, then normal (not wide-packet group) mode should be used and the number of packet group IDs is limited to 1,024.
If packets are 80 bytes or larger, then wide-packet group mode may be used. Two different scenarios apply when using wide-packet group mode:
If sequence checking is enabled, then the number of packet group IDs is limited to 8,192.
If sequence checking is not enabled, then the number of packet group IDs is limited to 128k.

Each OC192c port incorporates a set of 10 LEDs, as described in Table 26-10.
