About the Finisar FTLF1621P2WCL
The Finisar FTLF1621P2WCL (now a Coherent Corp. product, formerly II-VI) is a SFP OC-48 LR-2 / STM L-16.2 multirate (2.67G) optical transceiver for up to 2.67 Gb/s links at 1550nm DFB + APD over SMF, with reach up to 80km. It is a commercial-temperature part. It belongs to Finisar's FTLF1621P2 family, which has 4 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: Gigabit Ethernet, 1/2/4G Fibre Channel SAN, SONET OC-48 / STM-16 and CWDM/DWDM metro links.
- Up to 2.67Gb/s bi-directional data links
- Hot-pluggable SFP footprint
- Built-in digital diagnostic functions
- Uncooled 1550nm DFB laser transmitter
- APD receiver
- Metal enclosure for lower EMI
FTLF1621P2WCL: frequently asked questions
What is the Finisar FTLF1621P2WCL?
The FTLF1621P2WCL is a Finisar SFP transceiver for OC-48 LR-2 / STM L-16.2 multirate (2.67G) at up to 2.67 Gb/s. Finisar is now part of Coherent Corp. (formerly II-VI), and the part number is unchanged. It is used for Gigabit Ethernet, 1/2/4G Fibre Channel SAN, SONET OC-48 / STM-16 and CWDM/DWDM metro links.
What is the maximum distance of the FTLF1621P2WCL?
The FTLF1621P2WCL is specified for up to 80km over SMF. Long-reach optics may need an attenuator on short links; we can advise based on your link loss.
Which fiber and connector does the FTLF1621P2WCL use?
The FTLF1621P2WCL works at 1550nm DFB + APD over SMF. Both ends of a link must use the same optical standard.
Does the FTLF1621P2WCL support DDM / digital diagnostics?
Yes. Built-in digital diagnostic functions. Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Will the FTLF1621P2WCL work in my Cisco, Juniper, Arista or HPE switch?
The FTLF1621P2WCL follows the SFP 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.
FTLF1621P2WCL vs FTLF1621P2BTL: what is the difference?
Both are in Finisar's FTLF1621P2 family. They differ in temperature grade (commercial vs industrial). Pick the variant that matches your temperature, latch and wavelength needs.
What temperature range is the FTLF1621P2WCL rated for?
The FTLF1621P2WCL is a commercial-temperature part. Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTLF1621P2WCL part number mean?
The FTLF prefix marks Finisar's SFP / SFP28 / SFP56 family (incl. Fibre Channel). The C letter in the suffix usually marks the commercial temperature grade. The remaining characters identify the optical design and build variant.
Is the FTLF1621P2WCL still available?
The FTLF1621P2WCL 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 FTLF1621P2WCL price in India and how do I order?
The Finisar FTLF1621P2WCL 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 FTLF1621P2WCL need?
It runs from 3.3 V with power dissipation of <700 mW typical.
