About the Finisar FTRJ1321P1WTL
The Finisar FTRJ1321P1WTL (now a Coherent Corp. product, formerly II-VI) is a SFP OC-48 SR multirate (2.67G), non-RoHS optical transceiver for up to 2.67 Gb/s links at 1310nm over SMF, with reach up to 2km. It is an industrial-temperature part. It belongs to Finisar's FTRJ1321P1 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: 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 FP 1310nm laser transmitter
- Very low jitter
- Low power dissipation <700mW typical
FTRJ1321P1WTL: frequently asked questions
What is the Finisar FTRJ1321P1WTL?
The FTRJ1321P1WTL is a Finisar SFP transceiver for OC-48 SR multirate (2.67G), non-RoHS 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 FTRJ1321P1WTL?
The FTRJ1321P1WTL is specified for up to 2km over SMF. 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 FTRJ1321P1WTL?
Per the Finisar family datasheet, the FTRJ1321P1WTL transmits −9.5 to −3 dBm and has a receiver sensitivity of −18 dBm @ OC-48; −21 dBm @ 2x FC; −22 dBm @ GbE and OC-12; −23 dBm @ OC-3. Maximum receiver input is 0 dBm (upper bound of sensitivity-row range).
Does the FTRJ1321P1WTL support DDM / digital diagnostics?
Yes. Built-in digital diagnostic functions. Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which fiber and connector does the FTRJ1321P1WTL use?
The FTRJ1321P1WTL works at 1310nm over SMF. Both ends of a link must use the same optical standard.
Will the FTRJ1321P1WTL work in my Cisco, Juniper, Arista or HPE switch?
The FTRJ1321P1WTL 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.
FTRJ1321P1WTL vs FTRJ1321P1BTL: what is the difference?
Both are in Finisar's FTRJ1321P1 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 FTRJ1321P1WTL rated for?
The FTRJ1321P1WTL is an industrial-temperature part (per Finisar's part-number temperature code). Industrial grade suits outdoor cabinets, telecom huts and plant floors.
What does the FTRJ1321P1WTL part number mean?
The FTRJ prefix marks Finisar's earlier-generation SFP / SFF family. The I letter in the suffix usually marks the industrial temperature grade. The remaining characters identify the optical design and build variant.
Is the FTRJ1321P1WTL still available?
The FTRJ1321P1WTL 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 FTRJ1321P1WTL price in India and how do I order?
The Finisar FTRJ1321P1WTL 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 FTRJ1321P1WTL need?
It runs from 3.3 V (3.00–3.60 V) with power dissipation of <700 mW typical (Icc 165–300 mA).
