Finisar announces transceiver modules for metropolitan area networks

Sept. 13, 2001--Finisar Corporation, a technology provider of gigabit fiber optic solutions for high-speed data and telecommunication networks, announced its new line of CWDM APD GBIC modules and Small Form Factor SONET OC-48 Intermediate Range optical transceivers.

Finisar Corporation (Nasdaq: FNSR), a technology provider of gigabit fiber optic solutions for high-speed data and telecommunication networks, announced its new line of Coarse Wave Division Multiplexing (CWDM) APD GBIC modules, the FTR-1621-xx and FTR-1619-xx. Using Finisar's advanced APD technology, these transceivers are designed expressly for metropolitan area networks (MANs) requiring high-speed, optical communications at data rates from 125Mbps to 2.7Gbps and link budgets up to 30dB.

The FTR-1621-xx and FTR-1619-xx GBICs provide a cost-effective solution for metro access topologies where gigabit-rate signals need to be transported between locations separated by metropolitan distances. Finisar's CWDM GBICs work with Finisar OADMs and Mux/Demuxes to create sophisticated metropolitan area networks that address the key issues for network providers: transparency, scalability and cost-effectiveness.

The FTR-1621-xx is a multi-rate GBIC that operates at data rates from 125Mbps to 2.7Gbps with 28dB receiver sensitivity. The FTR-1619-xx operates at 1.0625Gbps Fibre Channel and 1.25Gbps Gigabit Ethernet data rates with 30dB receiver sensitivity.

The FTR-1621-xx and FTR-1619-xx are available in 8 wavelengths: 1470, 1490,1510, 1530, 1550, 1570, 1590 and 1610 nm.

As in all other Finisar optical GBIC modules, "smart" digital diagnostic functions are provided. 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. They allow telecommunication and data communications companies to implement reliable performance monitoring of the optical link in a very accurate and cost-effective way.

Optical transceivers are utilized by telecommunications and networking equipment manufacturers in their optical transmission systems, to convert high-speed electrical signals to optical signals and vice-versa for transmission over fiber optic cables.

The company also announced its full line of Small Form Factor SONET OC-48 Intermediate Range (IR) optical transceivers, the FTRJ-1420 and FTRJ-1520. These 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 fully compatible with Serial ID as defined by the SFP MSA. These digital diagnostic functions provide calibrated, absolute real time measurements of the laser bias current, the transmitted optical power, the received optical power, and the internal transceiver temperature and supply voltage. They allow telecommunication and data communications companies to implement reliable performance monitoring of the optical link in a very accurate and cost-effective way.

Additionally, 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 create very cost-effective 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 respectively compliant with SONET OC-48 IR-1 and IR-2 (SDH STM S-16.1 and S-16.2) standards, as defined in Bellcore GR-253 (and ITU-T G.957). These new products are complementary to Finisar's existing line of SONET OC-48 SR (Short Reach) (SDH STM I-16) Small Form Factor transceivers, available also in SFF and SFP MSA form factors.

Since they occupy much less circuit board space than their predecessors, SFF and SFP transceivers allow telecommunications and networking equipment manufacturers to cost-effectively increase the port density of their optical transmission systems.

Optical transceivers are utilized by telecommunications and networking equipment manufacturers in their optical transmission systems, to convert high-speed electrical signals to optical signals and vice-versa for transmission over fiber optic cables.
