About the Finisar FTRJ1721SMCL
The Finisar FTRJ1721SMCL (now a Coherent Corp. product, formerly II-VI) is a SFF 2x10 OC-48 LR-1 multirate (2.67G), non-RoHS optical transceiver for up to 2.67 Gb/s links at 1310nm APD over SMF, with reach up to 40km. It is a commercial-temperature part. It belongs to Finisar's FTRJ1721S 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
- Standard 2x10 pin SFF footprint (MSA compliant)
- Uncooled 1310nm DFB laser transmitter
- Low power dissipation <900mW typical
- Extended operating temperature range: -10°C to 70°C
FTRJ1721SMCL: frequently asked questions
What is the Finisar FTRJ1721SMCL?
The FTRJ1721SMCL is a Finisar SFF 2x10 transceiver for OC-48 LR-1 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 FTRJ1721SMCL?
The FTRJ1721SMCL is specified for up to 40km 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 FTRJ1721SMCL?
Per the Finisar family datasheet, the FTRJ1721SMCL transmits −2 to +3 dBm and has a receiver sensitivity of −27 dBm @ OC-48; −28 dBm @ 2x FC; −30 dBm @ GbE. Maximum receiver input is −9 dBm (upper bound of sensitivity-row range).
Which fiber and connector does the FTRJ1721SMCL use?
The FTRJ1721SMCL works at 1310nm APD over SMF. Both ends of a link must use the same optical standard.
Will the FTRJ1721SMCL work in my Cisco, Juniper, Arista or HPE switch?
The FTRJ1721SMCL follows the SFF 2x10 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.
FTRJ1721SMCL vs FTRJ1721SGCL: what is the difference?
Both are in Finisar's FTRJ1721S 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 FTRJ1721SMCL rated for?
The FTRJ1721SMCL is a commercial-temperature part (per Finisar's part-number temperature code). Choose an industrial (T) variant for outdoor or uncontrolled sites.
What does the FTRJ1721SMCL part number mean?
The FTRJ prefix marks Finisar's earlier-generation SFP / SFF family. The C letter in the suffix usually marks the commercial temperature grade. The remaining characters identify the optical design and build variant.
Is the FTRJ1721SMCL still available?
The FTRJ1721SMCL 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 FTRJ1721SMCL price in India and how do I order?
The Finisar FTRJ1721SMCL 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 FTRJ1721SMCL need?
It runs from 3.3 V (3.00–3.60 V) with power dissipation of <900 mW typical (Icc 230–330 mA).
