About the Finisar FTRJ1523P1BTL
The Finisar FTRJ1523P1BTL (now a Coherent Corp. product, formerly II-VI) is a SFP OC-3 LR-2 (155M), non-RoHS optical transceiver for 155 Mb/s links at 1550nm over SMF, with reach up to 80km. It is an industrial-temperature part. It belongs to Finisar's FTRJ1523P1 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: Fast/Gigabit Ethernet, SONET/SDH OC-3/OC-12, campus and access links, and legacy network upgrades.
- 155 Mb/s bi-directional data links
- Hot-pluggable SFP footprint
- Built-in digital diagnostics
- Uncooled DFB 1550nm laser transmitter
- Very low jitter

FTRJ1523P1BTL: frequently asked questions
What is the Finisar FTRJ1523P1BTL?
The FTRJ1523P1BTL is a Finisar SFP transceiver for OC-3 LR-2 (155M), non-RoHS at 155 Mb/s. Finisar is now part of Coherent Corp. (formerly II-VI), and the part number is unchanged. It is used for Fast/Gigabit Ethernet, SONET/SDH OC-3/OC-12, campus and access links, and legacy network upgrades.
What is the maximum distance of the FTRJ1523P1BTL?
The FTRJ1523P1BTL 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 FTRJ1523P1BTL use?
The FTRJ1523P1BTL works at 1550nm over SMF. Both ends of a link must use the same optical standard.
Does the FTRJ1523P1BTL 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 FTRJ1523P1BTL work in my Cisco, Juniper, Arista or HPE switch?
The FTRJ1523P1BTL 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.
FTRJ1523P1BTL vs FTRJ1523P1WTL: what is the difference?
Both are in Finisar's FTRJ1523P1 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 FTRJ1523P1BTL rated for?
The FTRJ1523P1BTL 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 FTRJ1523P1BTL 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 FTRJ1523P1BTL still available?
The FTRJ1523P1BTL 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 FTRJ1523P1BTL price in India and how do I order?
The Finisar FTRJ1523P1BTL 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 FTRJ1523P1BTL need?
It runs from 3.3 V with power dissipation of <700 mW typical.
