Designed to enable optical compatibility with existing carrier client interfaces VSR2000-3R2 per ITU-T G.693, they are compliant with 1 2 the CFP MSA , IEEE 802.3bg 40GBASE-FR and OTU3 requirements specified in ITU- T G.709. Digital diagnostics functions are available via an MDIO interface, as specified by the CFP MSA. The optical transceiver is compliant per the RoHS Directive 3 4 2011/65/EU . See Finisar Application Note AN-2038 for more details .

B1 Page 1 FTLQ1381N7NL Product Specification I. General Description 1 The FTL1381N7NL is based on the CFP Multi-Source Agreement (MSA ), which defines the form factor of an optical transceiver that can support 40Gbit/s interfaces for Ethernet, Telecommunications standards or other interconnect applications. The nominal signaling lane rate is 10Gbit/s per lane and supports XLAUI, OTL3.4, and STL256.4 electrical interface specifications. Supported aggregate data rates range from 39.8Gb/s (SONET OC-768/SDH STM-256 ) up to 44.6Gb/s (OTU3e). The module requires a system reference clock at electrical lane- rate divided by 64 (155MHz) or divided by 16 (622MHz). During power up or hot plug insertion the reference clock must be present in the low power mode to ensure compliant locking behavior upon start up; if the clock is not present or subsequently removed during module provisioning, Finisar recommends performing a module reset. To ensure correct module operation the Tx and Rx reference clock registers must be set to match the supplied reference clock frequency. The module has the option to incorporate a clock jitter filter based on a narrow-band PLL. This 40G NRZ CFP was designed to support very short reach (VSR) optical networking connections characterized by single mode fiber link lengths from 2m to 2 km. The FTL1381 was developed to support 40GBASEFR PMD but is also intended to be compliant with application VSR2000-3R2 as defined in ITU-T G.693. The CFP module is designed to be hot pluggable and the host system or the module shall not be damaged by insertion or removal of the module. The electrical interface consists of a 148-pin connector and support real-time control functions via the hardware pins. The monitoring, alarms and control functions are supported via an MDIO bus and the module is designed to operate from 0C to +70C case temperature. The power consumption meets class 1 power requirements of 8W. The optional loopback 1 functionality defined by the MSA is not supported. Note: For modules with Hardware Rev 1.2 or lower, the maximum supported lane to lane offset is 2 bytes (32 bytes of lane offset is supported with HW Rev 1.3 or higher); therefore during module operation in SDH mode per G.707 Amendment 2 it is recommended to ensure the framer is set to operate with 0 bytes of time offset between lanes. Note: TX_LOSF alarm is defined as the logical OR of TX_FIFO_ERROR, TX_LOCK_ERROR and TX_OUT_OF_ALIGNMENT. The TX_OUT_OF_ALIGNMENT Alarm will be muted when operating on Gigabit Ethernet mode.
