OC-48 Small Form Factor Optical Transceivers

Finisar just unleashed a line of Small Form Factor SONET OC-48 Intermediate Range (IR) optical transceivers called the FTRJ-1420 and FTRJ-1520. The transceivers use DFB laser technology and are designed for SONET OC-48 (SDH STM-16) applications of approximately 15km (IR-1) and 40km (IR-2), respectively. The FTRJ-1420 and FTRJ-1520 product lines include several MSA form factors: 2x5 pin SFF, 2x10 pin SFF and Pluggable SFP. The 2x10 SFF versions provide analog diagnostic information. The Pluggable SFP versions support Finisar's "SmartSFP" digital diagnostics and monitoring functions, which are accessed through a 2-pin serial bus that is compatible with Serial ID as defined by the SFP MSA. These digital diagnostic functions provide calibrated, real time measurements of the laser bias current, the transmitted optical power, the received optical power, and the internal transceiver temperature and supply voltage and allow telecommunication and data communications companies to implement performance monitoring of optical links. The Pluggable SFP version of the OC-48 IR-2 product (FTRJ-1520-7D-xx) can be supplied in eight different Coarse Wave Division Multiplexing (CWDM) wavelengths: 1470, 1490,1510, 1530, 1550, 1570, 1590 and 1610 nm. They can be deployed with Finisar Optical Add/Drop Multiplexers (OADM) and 4x1/8x1 Mux/Demux devices to wavelength management solutions, allowing several OC-48 signals to be transported between locations separated by metropolitan distances over the same fiber optic media. The FTRJ-1420 and FTRJ-1520 transceivers are compliant with SONET OC-48 IR-1 and IR-2 (SDH STM S-16.1 and S-16.2) standards respectively, as defined in Bellcore GR-253 (and ITU-T G.957).
