About the Finisar FTLX1442E2
The Finisar FTLX1442E2 (now a Coherent Corp. product, formerly II-VI) is a X2 10GBASE-LR (XAUI) optical transceiver for 10 Gb/s class links at 1310nm over Duplex SMF SC, with reach up to 10km. It is a commercial-temperature part. It belongs to Finisar's FTLX1442 family, which has 2 orderable variants that differ by temperature grade, latch, receiver build or wavelength channel. This is a legacy Finisar part; we help buyers find remaining stock or a current Coherent alternative. Typical uses: 10G Ethernet, 10G Fibre Channel, SONET OC-192 / OTN and DWDM metro / DCI links.
- Hot pluggable X2 MSA form factor
- Full duplex transmission mode
- Digital Optics Monitoring (DOM)
- De-latch mechanism with low extraction force
- Transmission distance of 10km
- Total power consumption: 3.5 W maximum
FTLX1442E2: frequently asked questions
What is the Finisar FTLX1442E2?
The FTLX1442E2 is a Finisar X2 transceiver for 10GBASE-LR (XAUI) at 10 Gb/s class. Finisar is now part of Coherent Corp. (formerly II-VI), and the part number is unchanged. It is used for 10G Ethernet, 10G Fibre Channel, SONET OC-192 / OTN and DWDM metro / DCI links.
What is the maximum distance of the FTLX1442E2?
The FTLX1442E2 is specified for up to 10km over Duplex SMF SC. Long-reach optics may need an attenuator on short links; we can advise based on your link loss.
What is the optical power budget of the FTLX1442E2?
Per the Finisar family datasheet, the FTLX1442E2 transmits −8.2 to +0.5 dBm (avg); OMA −5.2 dBm min and has a receiver sensitivity of −12.6 dBm (OMA). Maximum receiver input is +1.5 dBm.
Does the FTLX1442E2 support DDM / digital diagnostics?
Yes. Digital Optics Monitoring (DOM). Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTLX1442E2 use?
The FTLX1442E2 works at 1310nm over Duplex SMF SC. Both ends of a link must use the same optical standard.
Will the FTLX1442E2 work in my Cisco, Juniper, Arista or HPE switch?
The FTLX1442E2 follows the X2 MSA, so it fits any matching port. It carries Finisar's own EEPROM programming; switches that check the module vendor may need a configuration setting or a vendor-branded optic. Send us your switch model and we confirm before dispatch.
FTLX1442E2 vs FTLX1442F2: what is the difference?
Both are in Finisar's FTLX1442 family and share the same core optics; the suffix marks a different build option (latch, receiver or ordering variant). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTLX1442E2 rated for?
The FTLX1442E2 is a commercial-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTLX1442E2 part number mean?
The FTLX prefix marks Finisar's 10G family (SFP+, XFP, X2, XENPAK). The C letter in the suffix usually marks the commercial temperature grade. The remaining characters identify the optical design and build variant.
Is the FTLX1442E2 still available?
The FTLX1442E2 is a legacy Finisar part, so new production is limited or ended. Next Gen Networks helps source remaining genuine stock and can suggest a current Coherent alternative with the same reach and wavelength.
What is the FTLX1442E2 price in India and how do I order?
The Finisar FTLX1442E2 price in India depends on quantity, delivery city and current stock. Next Gen Networks supplies it with a GST invoice (input tax credit ready) and pan-India dispatch from New Delhi. Send the part number, quantity and delivery city on WhatsApp +91-7827955775 or email Sales@nextgennetworks.in for a GST quote.
What power does the FTLX1442E2 need?
It runs from +5.0 V, +3.3 V, APS +1.2 V with power dissipation of 3.5 W max.
